The development of Vivitar Series 1 Solid Catadioptric Telephoto Lenses represents a significant achievement in U.S. manufactured premium optics. Working in conjunction with the U.S. optical firm of Perkin-Elmer Corporation, Vivitar has incorporated the finest characteristics of intricate astronomical optics into a line of consumer and industrial lenses priced within reach of the advanced amateur or professional photographer.
With the introduction of Vivitar Series 1 Solid Catadioptric Telephoto Lenses, Vivitar and Perkin-Elmer have made optical technology previously applied only in space exploration and other highly advanced sciences, available to the general public. The incredibly compact size is achieved using spherically shaped lens elements which are pieced together to form virtually a single solid element. This unique process results in three outstanding benefits for the photographer. First, the lens maintains its precise optical alignment throughout extreme temperature variations allowing you to move from freezing to blistering climates without loosing maximum sharpness. Secondly, the amazingly short physical length of the lens reduces the horizontal and vertical travel of the front of the lens in relation to the film plane, thus increasing the sharpness of hand-held shots. Finally, the "solid" glass construction results in an extremely high resistance to damage by shock, a major problem with conventional mirror optics. This combination of environmental resistance, short physical length, and shock resistance assures you of superb performance under the most demanding conditions.
Filter provision: 35.5mm at the rear of the lens, inside the T-mount. Filters included are Series 1 VMC close tolerance UV haze, K2, 4X ND, and 25A. Screw-in hood, detachable tripod socket, filters, lens case , front and rear lens caps included.
Minolta showed a 500 mm f/8 lens that is the most compact of all, they claim, while Vivitar has a Series 1 "solid cat" (mirror design with minimum air spaces) 800 mm f/11 that's also very short. Both can be handheld with some care.
... Also in lenses, Vivitar introduce in summer next year two Series 1 enlarging lenses [...], and an 800mm f/11 version of their solid catadioptric design - fitted in the same 108mm diameter, 84mm long barrel as their 600mm f/8.
Made by Perkin Elmer.
The owner's manual is dated 7/78, so the lens existed already in 1978. This is also confirmed by the above-cited publication from the Journal of the Biological Photographic Association.
Ultra-slow full-frame super telephoto prime lens • 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.
Genres or subjects of photography (4):
Distant subjects • Distant landscapes with perspective compression effect • Wild nature • Travel photography
Recommended slowest shutter speed when shooting static subjects handheld:

Vivitar Series 1 program was an international effort dedicated to designing and producing advanced-technology optical systems for the professional and advanced amateur in 35mm film photography. These lenses were designed by Vivitar specialists and produced by third-party manufacturers such as Cosina, Kino Precision, Komine and Tokina. Catadioptric lenses were developed and manufactured in the USA in collaboration with the reflex lens specialists of the Perkin-Elmer Corporation, a company with vast experience in satellite-deployed astronomical optics. As Vivitar decided not to aggressively pursue the AF technology, all Series 1 AF lenses not only were produced, but also designed by Sigma.

Cannot compare the lens to itself.
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".
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/11 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.
