Manufacturer description

The 150-500mm F/5-6.7 Di III VC VXD (Model A057) zoom lens for Sony E-mount full-frame mirrorless cameras upends conventional wisdom for ultra-telephoto zoom lenses, with a very compact design and high image quality. The 150-500mm F5-6.7 achieves a 500mm focal length while retaining a compact size, with a length of just 209.6mm (8.3 in) and a maximum diameter of 93mm, enabling comfortable handheld shooting. The design places major emphasis on image quality. The optical construction features 25 elements in 16 groups and utilizes special lens elements and hybrid aspherical lens elements to control various potential aberrations such as chromatic aberrations. The 150-500mm F5-6.7 zoom is also equipped with a high-speed, high-precision linear motor focus mechanism VXD (Voice-coil eXtreme-torque Drive) and VC (Vibration Compensation), ensuring that no photogenic moment is ever missed. Additionally, the lens has a MOD (Minimum Object Distance) of 0.6m (23.6 in) at the 150mm end and remarkable overall usability. The Arca-Swiss compatible tripod mount has strap attachment holes and there are various features to support outdoor shooting, including Moisture-Resistant Construction and Fluorine Coating. The 150-500mm F5-6.7 is a highly versatile lens that lets you capture a wide array of subjects ranging from landscapes and birds to sports and wildlife photography. You will be amazed when you experience the powerful and unique world of ultra-telephoto lenses for yourself.

Considering its pairing with mirrorless cameras, TAMRON pursued a compact size that allows handheld shooting while developing the 150-500mm F5-6.7. With a length of 209.6mm (8.3 in) and maximum diameter of 93mm, the 150-500mm F5-6.7 is astonishingly compact for a 500mm-class ultra-telephoto zoom lens built for use on full-frame mirrorless cameras. Even when extended to the 500mm telephoto end, the lens has a suppressed length of around 283mm (11.1 in). Another distinctive feature is that the arc of rotation of the zoom ring is small—only 75°—which enables swift adjustment to the desired focal length with minimal movement.

In addition to covering a broad range of focal lengths, the 150-500mm F5-6.7 zoom has high resolving power with excellent image-rendering performance across the entire zoom range. The optical construction features 25 elements in 16 groups. The effective placement of special lens elements—including XLD (eXtra Low Dispersion), LD (Low Dispersion) and hybrid aspherical lens elements—enables the 150-500mm F5-6.7 to produce clear images while controlling chromatic aberrations. BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating is used to suppress ghosting and flare, which commonly occur under backlit conditions. These features allow the lens to produce finely detailed images of a wide variety of subjects including wild animals, birds, nature and sports, while producing soft and beautiful bokeh effects.

The 150-500mm F5-6.7 zoom’s AF drive system is equipped with the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. VXD delivers extreme high-speed and high-precision movement and ensures exceptionally responsive performance. Even when shooting at the ultra-telephoto end with a focal length of 500mm, the 150-500mm F5-6.7 enables comfortable, stress-free focusing at all shooting distances from near to far. Focus tracking performance is also very high, facilitating shooting of fast-moving subjects, such as when photographing wild birds, sports, vehicles and wildlife in general. The linear motor also suppresses drive noise and vibrations during focusing, making it ideal for shooting both still photos and video in environments that demand quietness.

When shooting in the ultra-telephoto range, even the smallest vibrations can lead to loss of image clarity. The 150-500mm F5-6.7 is equipped with VC (Vibration Compensation) functionality to support sharp images despite unavoidable camera shake. VC delivers powerful support for handheld shooting of scenes with low light levels, such as evening scenes and indoor shots, without the use of a tripod. The lens also features a VC mode selection switch with three modes including a dedicated panning mode (Mode 1: Standard, Mode 2: Exclusively for Panning, and Mode 3: Framing Priority), thereby enabling selection of the ideal VC mode to match shooting conditions and preferences.

The 150-500mm F5-6.7 zoom lets users freely enjoy telephoto macro shooting of subjects at closeup distances. The lens has an MOD (Minimum Object Distance) of 0.6m (23.6 in) at the 150mm wide-angle end, and 1.8m (70.9 in) at the 500mm telephoto end. More remarkably, the maximum magnification ratio at the 150mm end is 1:3.1, offering excellent close-up shooting capabilities for an ultra-telephoto zoom lens. The versatile performance of the 150-500mm F5-6.7 enables shooting of a diverse range of scenes from plants and insects to closeup tabletop photos. It also allows users to shoot very dramatic images because it gives the illusion that the distance between objects is less than in real life. Secondarily, it’s also possible to get interesting head-and-shoulder portraits because of this compression effect.

In the development and design of the 150-500mm F5-6.7 zoom, TAMRON emphasized usability so that users can fully immerse themselves in the world of ultra-telephoto zoom lenses without minor annoyances:

  • The end of the included lens hood is protected with flexible, shock-absorbing front rim to prevent cracks and damage.
  • The arc of rotation of the zoom ring is only 75° to enable swift adjustment to the desired focal length with minimal movement.
  • The FLEX ZOOM LOCK mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot at any angle without the lens extending unintentionally.
  • The design of the four slide switches has been improved for better operability based on ergonomics. The sloped bevel around the slide switch draws your finger naturally to the right position. To prevent accidental operation, for example, when removing the lens from a case or camera bag, the switches have a low profile. This new design provides a smooth and comfortable user experience.
  • Strap attachment holes are conveniently located in the Arca-Swiss compatible tripod mount, and the overall balance with the strap attached, with regard to center of gravity, is excellent.

TAMRON’s new 150-500mm F5-6.7 is compatible with many of the advanced features that are specific to mirrorless cameras. These include:

  • Fast Hybrid AF
  • Eye AF
  • Direct Manual Focus (DMF)
  • In-camera lens correction (shading, chromatic aberration, distortion)
  • Camera-based lens unit firmware updates

A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.

For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.

TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints.

Typical application / 典型的なアプリケーション

distant subjects, distant landscapes with perspective compression effect, sports in good lighting conditions, wild nature

Recommendations / 推奨事項

  • Use of a tripod is recommended due to heavy weight of the lens.
  • If you are into sports photography, consider acquiring a fast telephoto zoom lens.

Quality control issues

The manufacturer of this lens does not provide adequate quality control. If you do decide to purchase this lens, do not order it online, but choose the best copy available in the store. In any case, there may also be problems with the build quality, and warranty repairs can take months.

Model produced in a small batch. It is collectible and can only be found on the secondary market.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Voice-coil eXtreme-torque Drive

Focusing distance range limiter

The lens features focusing distance range limiter which allows to choose between the following focusing distance ranges:

FULLFull range of focusing distances.
3m - ∞Range of focusing distances suitable for shooting distant subjects.
15m - ∞Range of focusing distances suitable for shooting distant subjects.

By setting the suitable focusing distance range, the actual autofocusing time can be shorter.

AF/MF

AFAutofocus mode.
MFManual focus mode.

Aspherical elements

Aspherical elements (ASPH, XA, XGM) are used in wide-angle lenses for correction of distortion and in large-aperture lenses for correction of spherical aberration, astigmatism and coma, thus ensuring excellent sharpness and contrast even at fully open aperture. The effect of the aspherical element is determined by its position within the optical formula: the more the aspherical element moves away from the aperture stop, the more it influences distortion; close to the aperture stop it can be particularly used to correct spherical aberration. Aspherical element can substitute one or several regular spherical elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Use of aspherical elements has its downsides: it leads to non-uniform rendering of out-of-focus highlights. This effect usually appears as "onion-like" texture of concentric rings or "wooly-like" texture and is caused by very slight defects in the surface of aspherical element. It is difficult to predict such effect, but usually it occurs when the highlights are small enough and far enough out of focus.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Canon's Super UD, Nikon's Super ED, Pentax' Super ED, Sigma's FLD ("F" Low Dispersion), Sony' Super ED and Tamron's XLD glasses are the highest level low dispersion glasses available with extremely high light transmission. These optical glasses have a performance equal to fluorite glass.

High-refraction low-dispersion elements

High-refraction low-dispersion elements (HLD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

High Index, High Dispersion elements

High Index, High Dispersion elements (HID) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Anomalous partial dispersion elements

Anomalous partial dispersion elements (AD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Fluorite elements

Synthetic fluorite elements (FL) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. Compared with optical glass, fluorite lenses have a considerably lower refraction index, low dispersion and extraordinary partial dispersion, and high transmission of infrared and ultraviolet light. They are also significantly lighter than optical glass.

According to Nikon, fluorite easily cracks and is sensitive to temperature changes that can adversely affect focusing by altering the lens' refractive index. To avoid this, Canon, as the manufacturer most widely using fluorite in its telephoto lenses, never uses fluorite in the front and rear lens elements, and the white coating is applied to the lens barrels to reflect light and prevent the lens from overheating.

Short-wavelength refractive elements

High and specialized-dispersion elements (SR) refract light with wavelengths shorter than that of blue to achieve highly precise chromatic aberration compensation. This technology also results in smaller and lighter lenses.

Blue Spectrum Refractive Optics

Organic Blue Spectrum Refractive Optics material (BR Optics) placed between convex and concave elements made from conventional optical glass provides more efficient correction of longitudinal chromatic aberrations in comparison with conventional technology.

Diffraction elements

Diffraction elements (DO, PF) cancel chromatic aberrations at various wavelengths. This technology results in smaller and lighter lenses in comparison with traditional designs with no compromise in image quality.

High refractive index elements

High refractive index elements (HR, HRI, XR etc) minimize field curvature and spherical aberration. High refractive index element can substitute one or several regular elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Apodization element

Apodization element (APD) is in fact a radial gradient filter. It practically does not change the characteristics of light beam passing through its central part but absorbs the light at the periphery. It sort of softens the edges of the aperture making the transition from foreground to background zone very smooth and results in very attractive, natural looking and silky smooth bokeh.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance from the lens mount to the film or sensor can also be different.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Electromagnetic diaphragm control system

Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.

Convex protruding front element

The convex front element protrudes from the lens barrel, making it impossible to use filters.

Fixed focus

There is no helicoid in this lens and everything is in focus from the closest focusing distance to infinity.

Overall linear extension

The entire lens optical system moves straight backward and forward when focusing is carried out. This is the simplest type of focusing used mainly in wide-angle and standard prime lenses. It has the advantage of introducing relatively little change in aberrations with respect to change in focusing distance. With telephoto and super telephoto lenses this method becomes less beneficial in terms of operability because of the increased size and weight of the lens system.

Front group linear extension

The rear group remains fixed and only the front group moves straight backward and forward during focusing. This method is primarily used in zoom lenses and allows to design comparatively simple lens construction, but also places restrictions on zoom magnification and size reduction.

Front group rotational extension

The lens barrel section holding the front lens group rotates to move the front group backward and forward during focusing. This method of focusing is also used only in zoom lenses.

Internal focusing (IF)

Focusing is performed by moving one or more lens groups positioned between the front lens group and the diaphragm.

Methods of internal and rear focusing have the following advantages:

Rear focusing (RF)

Focusing is performed by moving one or more lens groups positioned behind the diaphragm.

Methods of internal and rear focusing have the following advantages:

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Rotary zoom

The change of focal length is achieved by turning the zoom ring and the manual focusing - by turning the separate focusing ring.

Push/pull zooming allows for faster change of focal length, however conventional method based on the rotation of the zoom ring provides more accurate and smooth zooming.

Push/pull zoom

The change of focal length and the manual focusing is achieved by one and the same ring. The change of focal length happens when the photographer moves the ring towards the mount or backwards and the rotation of the ring leads to change of focus.

Push/pull zooming allows for faster change of focal length, however conventional method based on the rotation of the zoom ring provides more accurate and smooth zooming.

Zoom lock

The lens features a zoom lock to keep the zoom ring fixed. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.

Power Zoom

The lens features electronically driven zoom mechanism. It provides smoother, more natural zoom movements than you could accomplish by hand.

The Holy Trinity of lenses

The Holy Trinity of lenses refers to a three-lens set that covers a focal length range from the ultra-wide focal length of 14-16mm all the way long to the telephoto focal length of 200mm. The set typically consists of a 16-35mm ultra-wide angle zoom lens, a 24-70mm standard zoom lens and a 70-200mm telephoto zoom lens and usually represents the best constant-aperture zoom lenses in a manufacturer's lineup. The set is designed to cover almost every genre of photography, be it landscapes, architecture, portraits, weddings, sports, travel or even wildlife (with teleconverter). However, it is also expensive, large and heavy.

Efficiency of image stabilizer

The efficiency of image stabilizer is measured in stops and each stop corresponds to a two-times increase of shutter speed. For example, if you are shooting at focal length of 80mm and it is known that the efficiency of image stabilizer is 3 stops, it means that during handheld shooting at such focal length you can use shutter speed of 1/10 second which is exactly 23 times longer than the shutter speed 1/80 second needed to obtain sharp image in sufficient lighting conditions.

Hybrid IS

The image stabilizer has Hybrid IS technology which corrects not only angle but also shift camera shake, which is more pronounced in close-range shooting when a camera moves parallel to the imaging scene. Hybrid IS dramatically enhances the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.

XY-Shift

The image stabilizer has XY-Shift technology which corrects not only angle but also shift camera shake, which is more pronounced in close-range shooting when a camera moves parallel to the imaging scene. XY-Shift dramatically enhances the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.

Dynamic IS

The image stabilizer has Dynamic IS technology which especially effective when shooting while walking because it compensates strong camera shake. Dynamic IS activates automatically when the camera is set to movie shooting.

Mode 1

Corrects vertical and horizontal camera shake. Mainly effective for shooting still subjects.

Mode 2

Corrects vertical camera shake during following shots in a horizontal direction. Corrects horizontal camera shake during following shots in a vertical direction.

Mode 2

Corrects vertical camera shake during following shots in a horizontal direction.

Mode 2 (Intelligent OS)

The lens incorporates Intelligent OS with algorithm capable of panning in all directions. In Mode 2, the movements of subjects can be captured with panning effects even when the camera is moved horizontally, vertically, or diagonally — regardless of the position of the lens.

Mode 3

Corrects camera shake only during exposure. During panning shots, corrects camera shake during exposure only in one direction the same as Mode 2. Effective for following fast and irregulary moving subjects.

Panning Detection

The image stabilizer automatically detects panning and then corrects camera shake only in one direction.

Tripod Detection

It is often thought that image blur caused by camera shake can be prevented by using a tripod. Actually, however, even using a tripod may result in image blur because of tripod vibration caused by mirror or shutter movement at the time of exposure. The image stabilizer automatically differentiates the frequency of the vibration from that of camera shake, and changes algorithm to correct image blur caused by slight tripod vibration.

VR NORMAL

Corrects vertical and horizontal camera shake. Automatically detects panning and then corrects camera shake only in one direction.

VR ACTIVE

Corrects vertical and horizontal camera shake when shooting from a moving vehicle, or some other unstable position. Panning is not detected.

VR SPORT

Allows a continuous shooting frame rate and release time lag similar to those that are possible when image stabilizer is turned off. Automatically detects panning and then corrects camera shake only in one direction.

VR TRIPOD

It is often thought that image blur caused by camera shake can be prevented by using a tripod. Actually, however, even using a tripod may result in image blur because of tripod vibration caused by mirror or shutter movement at the time of exposure. The image stabilizer automatically differentiates the frequency of the vibration from that of camera shake, and changes algorithm to correct image blur caused by slight tripod vibration.
