Manufacturer description

The Tokina TM500 incorporates two mirror elements as a part of the entire optical composition plus it is the worlds most lightweight and compact 500mm-lens presently available.

Not only has the chromatic aberration been reduced to an invisible minimum but also the overall definition and resolution has been marginally improved. Even in Infrared Photography there is no need for any focusing compensation.

The most compact and most lightweight 500mm-lens available today

The overall diameter of this lens is only 78mm, and the overall length (from P-Mount to Barrel-Fringe) is only 88.2mm. And its weight of only 462 gram makes this precision lens the most compact and lightweight presently available.

Continuous Focusing

From the minimum focusing distance of 1.5m to infinity this lens is operated with continuous focusing, using a Helicoid Screw. The maximum magnification ratio at 1.5m is M=1:2.5.

Fixed Aperture

The preset aperture of f/8 does not require any trouble-some calculations, since it is a real aperture from the nearest focusing point to infinity. Even if you operate your TM500 with a flash unit, all you need to do is to follow the guide-number given by the flash and your exposure is always correct.

Fixed Mount

To achieve the highest possible standard, we have manufactured your mirror lens with a fixed mount for your camera, which results in a higher precision than conventional interchangeable mounts can offer.

[...]

Lens Hood

You find a separate lens hood with your TM500 and we strongly recommend its use. It will protect your lens from unwanted sidelight and flare and thus give you a better, more defined image. The hood, for easy carrying, has been attached upsidedown to the lens all you have to do is to remove it and screw it into its proper position.

When to detach a hood unscrew it.

Changing Filters

All optional and included filters have a thread-diameter of 35.5mm and are attached to the rear of the lens. Thus for a filter change you must first remove the lens from the camera. To screw a filter into place, please tighten it gently with the supplied filter-key, turning it clockwise. And counter-clockwise to remove it. A skylight-filter, ND-2x and NX-4x have been included with this 500mm lens unit, and they are packed separately with the lens. Select among them according to the requirements of the photographic situation and attach it to your lens as described above.

Note: Design and size of the flange of this lens are such as to be used with a filter only. The thickness of each filter has been carefully adjusted as to suit the optical characteristics of the lens components. You should therefore maintain one filter constantly attached to your lens.

From the editor

In the description (taken from the instruction manual), the manufacturer uses the code "TM500" for this lens, however in reality "RMC Tokina 500mm 1:8" is indicated on the front of the lens.

Typical application

distant subjects, distant landscapes with perspective compression effect, wild nature, travel

Comments

The front filter thread is not 77mm. I own three copies of this lens. The filter thread is something between 72mm and 77mm. I think it is 75mm but I am not sure because I have not found a 75mm thread and tried to screw it into the lens. But when I measure it with calipers it seems to be 75mm.


You’re right. Users say the same thing on various photographic forums:

– “I’ve seen it listed as 72mm, but it’s bigger than that. I tried a 72mm filter and it was too small, but not by much. So it’s not 72mm, but certainly not 77mm either.”

– “My Tokina 500/8 has a 75mm x 1.00 pitch thread for the metal hood on the front of the lens, which is completely non-standard for any filters (almost all filters are .75mm thread pitch). This effectively prevents the mounting of any filter directly to those threads on the lensbody.”

– “I do own this lens and its manual. Tokina DOES NOT RECOMMEND the use of front filters”

Funny thing is that on their official website Tokina states that the front filter size is 77mm. And on our website, we always fill out lens specifications based on manufacturer data. Since this was not the first case of misinformation from Tokina, once again I am convinced that the data about vintage Tokina lenses on their official website is a total mess and cannot be trusted 🙁

Thank you for pointing out this error.

Cannot compare the lens to itself.

Mirror/Reflex lens

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.

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.

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 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

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.

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.

Speed

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".

Electromagnetic diaphragm control system

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

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:

Modified M42 mount

The mount has been modified by the manufacturer to allow exposure metering at full aperture.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

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.

Semi-automatic diaphragm

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.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/8 on this lens, and cannot be adjusted.

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.

Teleconverters

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.

Lens caps

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.
