Undoubtly this is the longest telephoto lens in Hasselblad's optical arsenal. A powerful tool for bridging distance and compress perspective. It is the right optic for taking photos of subjects that cannot or must not be accessed, like interesting details of buildings, monuments, towers, dangerous animals, launching rockets, burning fires and the like. And it is an absolute must for nature and wildlife photographers working far away from parking lots, depending solely on their own feet for carying their equipment: The Tele-Apotessar T* 8/500 CF lens is surprisingly lightweight, a merit of the Tessar lens design principle. The lens comes with a very smooth internal focusing mechanism that can easily be operated with the camera hand-held in the typical Hasselblad manner. Having said this, we strongly recommend to use the Tele-Apotessar T* 8/500 CF lens with a professional grade tripod or monopod, because, due to its apochromatic correction, the optical performance is so high that it can not be fully utilized with hand-held shooting.
For this purpose the Tele-Apotessar T* 8/500 CF lens comes with the Hasselblad system tripod quick mount right under the center of gravity of camera and lens combined. Tripod usage also fosters accurate focusing in general, but especially at an aperture of f/8. The Hasselblad AcuteMatte bright focusing screen is a valuable item to have in the camera when shooting this lens. The lens barrel incorporates very efficient light baffling devices to control stray light.
The Tele-Apotessar T* 8/500 CF lens can be focused down to 5 meters, and the optic is designed with special attention to close-up performance - a valuable asset in wildlife photography. The focusing ring can move beyond infinity to allow use of this lens in a variety of temperature conditions.
Preferred use: editorial, documentation, preservation of historical monuments, nature and wildlife.
An optically-true telephoto lens with a physical length approximately 180mm or 7 inches shorter than its focal length.
Special types of optical glass with exceptional properties have been used in the design of the Tele-Apotessar lens.
The successful outcome has been a dramatic reduction in chromatic aberrations. Lateral color has been decreased, with the result that high-contrast subjects do not exhibit any color fringes on bright/dark edges.
Another special feature of the Tele-Apotessar lens is its internal focusing. The lens is focused by moving the rear element group whilst the front group remains stationary.
The large focusing ring is extremely smooth which undoubtedly results in more precise focusing.
Mounted on a tripod the centre of gravity remains virtually constant through focus changes.
This lens is an absolute essential for wild-life photographers as well as for shooting scenes under difficult conditions.
The lens was supplied with a ⌀93 lens shade, which also served as a filter holder for ⌀93 filters. Screw mount. It also fits the 350mm and 500mm Tele-Tessar C lenses and makes it possible to use ⌀93 filters with these lenses instead of ⌀86 which are being withdrawn.
Slow 6x6 medium-format medium telephoto prime lens • Apochromatic optical design • Professional model (Top class)
All glass elements in an optical system refract light in certain colors to a different extent. This leads to the effect that not all rays of light from a multi-colored subject are focused at a single imaging point – the result of this is chromatic aberration.In this lens, the chromatic aberration is minimized by apochromatic correction.A need for apochromatic correction arose with the increasing popularity of color film. Now, with high-resolution digital sensors, the need for superior control of chromatic aberrations is even more pertinent than when film changed from monochrome to color.

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.
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".
There is no helicoid in this lens and everything is in focus from the closest focusing distance to infinity.
Conventional lenses employ an all-group shifting system, in which all lens elements shift during focusing. The IF system, however, shifts only part of the optics during focusing. The advantages of the IF system are:
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.
The aperture setting is fixed at F/8 on this lens, and cannot be adjusted.
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.

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.
