Manufacturer description #1

The Tokina AT-X M100 f/2.8 PRO D Macro is a compact moderate tele macro lens for full frame format film and digital SLR cameras. The lens is available in Nikon F and Canon EF mounts. Light-weight and compact, the M100 is capability of life-sized (1:1) reproduction at 30 cm. The lens has high resolution, fast aperture, low distortion and low falloff. Beautiful soft bokeh makes this lens extremely attractive tool for macro, portraits, landscapes, art reproduction, commercial and general purpose shooting.

The Tokina AT-X M100 PRO D incorporates all the necessary features and provides all the main advantages for dedicated macro shooters. The Tokina AT-X M100 PRO D is capable of life-sized (1:1) reproduction at 30 cm. This allows photographers to have a little working distance from the subject and still obtain impressive magnification. Having some working distance is important when shooting easily startled subjects such as insects. Designed for full frame sensors, the focal length equivalent on a DSLR with an APS-C sensor turns to 150mm on Nikon camera and 160mm on Canon. This gives an advantage of shooting macro with 1.5x~1.6x larger magnification than a full frame camera. The focus range limiter switch on the lens body makes focusing faster saving time.

The Tokina AT-X M100 PRO D excels at shooting portraits. Due to the large the aperture and optical properties the lens creates magnificently soft bokeh in both the background and foreground while easily keeping a comfortable distance from the model. The focal length is short enough to allow easy and natural communication with the model, creating a feeling of comfort and creativity. This combined wit the fast f/2.8 aperture allows the lens to be used in the widest variety of shooting settings both indoor and outdoor.

Incorporated 9 bladed diaphragm creates beautiful, almost circular-shaped background highlights up to f/5.6 with effectively surpassed longitudinal chromatic aberration.

The Tokina AT-X M100 PRO D optical design suppresses curvature of field while maintaining high resolution across the entire image along with extremely low distortion, low falloff and perfectly controlled chromatic aberration. Multi-coating applied to optical elements effectively control flare and ghosting. Thanks to its optical design concepts the Tokina AT-X M100 PRO D has a convenient compact lens design. A careful balance of high-impact plastic on the exterior coupled with metal load bearing interior parts makes this lens mechanically solid for long-term reliability even during extensive field use.

A focus range limiter switch on the side of the lens locks the lens focus into or out of the macro focusing range to avoid excessive AF hunting.

The directions of the manual focusing ring matches the proprietary direction of Nikon and Canon lenses. A rubber grip ring near the rear of the lens is there for easy mounting and dismounting the lens. Black flocking inside the inner barrel prevents glare and unwanted reflections.

The front of the lens has a 55mm filter threads which extends during the focusing but does not rotate. This allows different filters including polarizers to be used for landscape or product photography.

Tokina's exclusive One-Touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the lens mount for manual focusing. You can immediately convert the focusing mode to MF and then focus without rushing. When doing so, you will have all the time to carefully observe the model while focusing and to further adjust the composition the way you want.


1. The Tokina AT-X M100 PRO D Nikon F mount does not incorporate AF drive motor, therefore the autofocus will not operate with Nikon DSLRs that do not have a focus motor in the camera body.

2. Tokina AT-X M100 PRO D for Nikon mount is based on the specifications of "Ai AF-D" Nikon lenses. When using with a Nikon DSLR camera or a film camera with CPU system, it is necessary to set the aperture ring to the minimum aperture value (f/32). When set on an aperture other than the minimum aperture value (f/32), a "FEE" error message flashes and the shutter cannot be released. To prevent accidental movements of the aperture ring from the minimum aperture value the ring can be locked in place with the small slide switch adjacent to the ring (to release the lock, slide the lever to the opposite side). When setting the aperture value to f/32 and then changing it by the dial on the camera, the aperture value displayed in the viewfinder will be other than f/32. At this time, the diaphragm blades do not move but will operate according to the aperture value displayed.

Manufacturer description #2

The AT-X 100 PRO D is a new macro lens capable of life-sized (1:1) reproduction at 11.8 in. (30 cm). The lens' multi-coating have been re-engineered to match the highly reflective silicon based CCD and CMOS sensors in today's digital SLR cameras. This lens gives the best of both worlds because optics still give full coverage and excellent sharpness on 35mm film. A macro lens that can handle both the digital and film worlds with ease.

The AT-X 100 PRO D also has a very convenient focus limiter switch that can lock the focus out of the closes focus making it focus faster when used as a moderate telephoto lens that is excellent portraits as well.

Other features of the AT-X 100 PRO D are:

  • Tokina One Touch Focus Clutch Mechanism for fast easy switching between manual and Auto focus.
  • 55mm non-rotating filter thread for use with macro ring flashes and special effects filters.
  • The AT-X 100 PRO D also comes with a deep bayonet mounted lens hood.

From the editor

The lens is a result of cooperation between Pentax and Tokina companies and known as the smc Pentax-D FA 100mm F/2.8 Macro in the Pentax K system.

The whole optical system of the lens moves considerably with focusing from infinity to the closest distance. The front element is deeply recessed inside the lens barrel which eliminates the need for a lens hood. Nevertheless, Tokina offers deep circular lens hood as a part of the package.

Typical application

portraits, travel, macrophotography and product photography

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.


In-camera motor

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.
0.3m - 0.36mRange of focusing distances suitable for shooting nearby subjects.
0.38m - ∞Range of focusing distances suitable for shooting distant subjects.

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

Tokina One Touch Focus Clutch Mechanism

Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. The rotation of the focusing ring to the infinity or to the closest focusing distance before switching the ring from AF setting to MF is not required. There is no need to change the AF/MF switch on Nikon camera bodies and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.

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 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),


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 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.

Flange focal distance

The flange focal distance (FFD), sometimes called the "flange back", is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Focal length

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.

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.

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.


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.


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.
