The new Vivitar Series 1 70-210mm continuous macro-focusing lens, unlike conventional zooms, allows you to zoom within the macro range, thus giving you greater compositional control. Finally, the new arrangement of 14 elements in 10 groups was discovered.
The individual design and exact positioning of each element was an incredible orchestration. The task called for a total reworking of the lens, requiring an extremely sophisticated computer program to deal with the multitude of variables.īased upon Vivitar's pioneering work on continuous-focusing Series 1 zoom lenses, the optical design team made an astounding discovery: front group focusing could be extended to include the macro range if the appropriate design configuration were found. Vivitar's experts quickly agreed that the original lens couldn't be improved upon with small design niceties. We wanted a lens that would do everything the old lens did yet be lighter, smaller, with even more features and demonstrably superior performance. The result? Macro capability, one-touch control and an extremely fast f3.5 maximum aperture.Īlmost from the beginning, the old 70-210mm became the standard of the industry.īut we wanted more. This was made possible by using a unique and proprietary computer optimization program. Suddenly, there was a zoom lens with the resolution characteristics of a fine fixed focal length lens. When the Series 1 70-210mm first appeared a decade ago (*), it radically changed the world's perception of zoom lenses. The Series 1 70-210mm lens story really must be told in two parts: the old and the new.
Vivitar's new Series 1 70-210mm f3.5 continuous macro-focusing zoom lens. **) Some basic information is missing in the specification as it was not provided by the manufacturer. Vivitar lenses booklet (September 1982).*) Sources of data: Manufacturer's technical data The zoom ratio is exactly 3 times, and the range itself is very convenient to use, especially for portrait shooting and certain tasks associated with sequential shooting. The lens has the old piston design - pull on the large rubberized 'piston' ring to change the focal length. Moreover, this is a 'correct' piston lens - the maximum focal length is available when the 'piston' is pushed as far forward as possible. It is a pity that the 'piston' constantly slides down to 210 mm by itself. As the focal length changes, the rear lens moves, drawing in and out air. In my reviews, I often write about the 'vacuum cleaner effect'. Its intensity level can be checked by eye in the direct meaning of the word. To do this, just bring the lens mount to the eye and zoom. Just do not press hard, otherwise you can injure the eyeball. The human eye is very sensitive to everything, including the air currents coming from the rear lens of the lens, which allows you to 'visually' feel the intensity of the effect. Old school photographers know that some lenses with some cameras can have such a strong vacuuming effect that it can be felt even near the eyepiece. The rear lens of the objective once again drives air through the inner compartment of the camera, where the mirrors, the focusing system, the shutter and the focusing screen are located, this can sometimes lead to faster clogging of the camera parts. Sometimes the effect of a vacuum cleaner is not so terrible, but of course it is better if it were not there at all.Ĭosina 70-210mm 1: 2.8-4 MC Macro with a hoodĪuto focusing with Cosina 70-210mm 1: 2.8-4 MC Macro lens available only when using him on cameras with built-in motor focusing.

#Vivitar 70 210 manual
There is no focus mode switch on the lens the transition to manual focus and back is carried out by switch on the camera, which is located near the camera mount, on some cameras it is not very convenient. Устройство aperture consists of all 9 not rounded petals. The lens has aperture control ring (in the photo the ring is easy to recognize by two rows of numbers from F / 2.8 to F / 22).
#Vivitar 70 210 install
To control the value aperture of any modern Nikon camera automatically, you need to install the ring aperture to position F / 22.
