Introducing the world's first 350mm F/5.6 Tele-Macro Catadioptric lens
Compact 350mm F/5.6 Tele-Macro Catadioptric with a fast F/5.6 aperture and the closest focusing distance of 1.1 meters
Features the optical techniques pioneered in the "Handheld Tamron 500mm Tele-Macro Catadioptric" and incorporates silver-evaporated Mangin mirrors with an ultra-high reflection value - 95% or more. Tamron's SP 500mm F/8 Tele-Macro Catadioptric lens has rapidly earned great popularity and respect among camera enthusiasts and professional photographers as the pioneering step toward more compact catadioptric lenses and achieving the system's remarkable Tele-Macro capability. The superior optical techniques already proven in the Tamron SP 500mm have now made possible the development of the world's first 350mm Tele-Macro Catadioptric lens. With its advantages of compactness and high speed, it is particularly suited to long-range photography of fast moving subjects.
Tamron's SP 350mm F/5.6 Catadioptric lens, with the extremely close focusing distance of 1.1 meters not found in other 350mm class lenses, uses rear reflex mirrors for its main and auxiliary mirrors similar to the Tamron SP 500mm F/8 lens. Both the primary and secondary mirrors are specially coated with silver for an extremely bright reflection value of 95% or more. (Compare this with the typical reflection value of 64% of conventional reflex mirrors coated with aluminum). Surface polishing accuracy of the silver-coated reflex mirrors is maintained to an ultra high precision level of one-eight Lambda; reflection efficiency is further increased by silver ion plating. Possible oxidation of the primary and secondary mirrors' silver surfaces has been completely overcome by using both a non-vaporised special ion plating and an ultra hard, three layer protective membrane more than three times as durable as the U.S. MIL Standard.
The high precision rear reflex mirrors and lens elements in monoblocks achieve the same high transmission factor (80% or more) common in dioptric system lenses. Additionally, the color aberration uncorrectable in dioptric system lenses, and changes in aberration caused when focusing, are reduced to absolute minimum levels by the rear reflex mirrors. Consequently, throughout the entire focusing range, from infinity to macro, a flat image quality excelling in high contrast and good color balance will be obtained.
Fast F/5.6 aperture
Tamron SP 350mm lens' fast F/5.6 aperture is capable of providing full meter and aperture coupling for full coordination with all the built-in lens functions of almost any popular 35mm SLR camera. The fast shutter speed possible dramatically reduce image blur on the picture, making handheld telephotography easier than ever. SP 350mm is also at home with indoor photography - stage actions, etc. - and brings new possibilities to the shooting of fast moving subjects.
Lightweight and compact - a truly portable ultra-telephoto
Tamron's unique employment of catadioptrics - the use of mirrors and dioptrics - has achieved unusual compactness and lightness to the 350mm class. SP 350mm measures only 79mm in total length; overall weight is a very modest 577 grams. The hand-held opportunities this portability opens will show themselves to particular advantage in shooting action scenes such as motor car races, baseball, distant wild animals, etc.
Continuous focusing (CF)
Focus in from infinity to macro (minimum object distance of 1.1 meters) in one continuous movement, without having to press a macro switchover button or lever.
The tele-macro feature enables an object to be photographed with a 1:2.5 magnification ratio at the minimum object distance of 1.1 meters. Because the 350mm lens is fully compatible to all automatic and manual camera functions, lighting (including auto flash) is maintained. Such versatility adds new dimensions to macro-photography.
The F-number is always the same, from infinity up to macro (minimum object distance of 1.1 meters). Troublesome calculations of exposure multiples have been eliminated; in auto flash photography, optimum exposure time can be obtained without any correction.
Exclusive filter set
Five specially made filters are supplied with the lens - Normal, ND4X, Y52, O56 and R60. The small-sized 30.5mm rear filters screw onto the rear element thread. Two other 30.5mm filters of ND2X and 81B are also available as an option.
The tripod mount ring features a convenient longitudinal position
The tripod mount ring allows one touch operation and rotates 90 degrees. Even after the lens with camera are mounted on the tripod, it is simple to switch to horizontal or a longitudinal position. During hand-held photography, this mount ring helps keep a steady hand.

Cannot compare the lens to itself.
A lens based on design principles used in large astronomical telescopes. It is a combination of mirror and lens elements. Incoming light is reflected twice on the mirror surfaces, resulting in compactness of the lens barrel and light weight relative to the focal length.
To adjust image brightness, neutral density or other filters are used, because lenses of this type are not equipped with diaphragms.
Sharpness of the focused image is unsurpassed because of the use of reflecting surfaces which do not cause any chromatic aberration.
Taken with this type of lens, the subjects in the out-of-focus range may appear as blurred rings or separate blurred lines.
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.
Sorry, no additional information is available.
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 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 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),
CF – crop-factor of a sensor,
FL – focal length of a lens.
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 can also be different.
The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.
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.
The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.
The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.
In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.
The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.
The distance from the front edge of the lens to the subject at the maximum magnification.
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".
Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.
The aperture setting is fixed at F/5.6 on this lens, and cannot be adjusted.
The diaphragm must be stopped down manually by rotating the detent aperture ring.
The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.
The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.
The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.
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.
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.
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.
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.
Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.
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.
Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.
Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.
Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
