Manufacturer description

atx-m series is targeting high speed growing mirrorless cameras market with high quality and yet superior cost performance optical lenses.

Preserving the Tokina's advanced technology (atx) new series is marked with "m" letter, that stands for "motif" and "mirrorless"- motivation that Tokina provides to photographer for creating unique and breathtaking photos with mirrorless cameras.

Tokina atx-m 56mm F1.4 X - featuring angle of view equal to approx. 85mm in full frame (standard angle) is designed as a highly popular optical gear for amateur or even semi - professional photographers to capture portraits, street portraits, street snaps and landscapes in still or video mode.

Exclusively designed to fit contemporary mirrorless cameras in terms of weight and size.

The basic property of mirrorless camera is compactness and lightweight. Incorporating made of metal mount and barrels for built quality we succeeded to create the lens light and small - perfect combination with Fujifilm X mount APS-C mirrorless cameras.

Tokina atx-m 56mm F1.4 X features fast f/1.4 aperture that creates more creamy and beautiful front and back bokeh, compared to standard and wide prime lenses and provides huge advantage in low light shooting.

Tokina atx-m 56mm F1.4 X incorporate accurate responsive AF system that fully communicates with the camera body. Quiet, accurate and fast focusing is realized by in-built ST-M focus motor.

Tokina atx-m 56mm F1.4 X is fully communicable with the camera body to support 5-Axis In-Body Image Stabilization.

Fujifilm's design philosophy has always been to be about dials on the cameras and emulating a traditional film shooting experience. Tokina atx-m 56mm F1.4 X incorporates aperture click-less ring allowing users to smoothly control aperture manually from f/1.4 to f/16 in video mode, but also automatically (position A) via camera setting in still mode.

The atx-m 56mm F1.4 X completes the trio line that covers major focal lengths - wide, standard and semi-tele to meet 3 important genres in photography - landscape, street snap and portrait.

Highlighted features:

  • Extremely compact and lightweight - perfect combination with Fujifilm X mount APS-C mirrorless cameras.
  • f/1.4 aperture for creamy and beautiful front and back bokeh and great light intake as a huge advantage in low light shooting.
  • Fast, but silent AF realized by ST-M focus motor.

  • Color balance tuning to fit Film Simulation modes of Fujifilm camera.
  • Click-less aperture ring to smoothly control aperture manually in video mode.

From the editor ⋅ 編集者から

Firstly, this lens is not Tokina's own development, but is the result of the design and manufacturing efforts of the Chinese company Viltrox. The same applies to the 23/1.4 and 33/1.4 models.

Secondly, Tokina is very late with this lens: there is currently no shortage of lenses with similar focal lengths and speeds, both APS-C and full-frame, in the Sony E system. And it will be more practical to buy a compact full-frame model like Sony Zeiss FE 55/1.8 or Sony FE 50/1.8, since you can migrate with them to a Sony full-frame camera in the future. As for the Fujifilm X system, it is not so extensive in this class of lenses, but the existing lenses from the camera manufacturer offer high image quality and impressive bokeh, and it is very difficult to compete with them in this sense.

Thirdly, the lens does not offer any significant advantages over models from other manufacturers. Internal focusing and stepping motor that this model is equipped with are now standard features of almost all lenses designed for mirrorless cameras. It turns out that the main competitive advantage of this lens is only its price. However, even here there is no point in purchasing the lens from Tokina because if you do not mind dealing with Chinese developments, then it makes sense to buy this lens directly from Viltrox. You will not lose anything, but only save money without overpaying for the Tokina brand name.

Beggars can't be choosers: Tokina stopped developing its own lenses back in 2016, but still wanted to make money in the digital imaging market, so it decided to expand the product range by rebranding some Viltrox lenses, whatever they are.

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.

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.
