According provided by Cosina 70-210mm 1: 2.8-4 MC Macro lens (AF, for Nikon F mount) many thanks to Andrei Petruk.
Cosina 70-210mm 1: 2.8-4 MC Macro is an old film zoom lens with good aperture. The lens was produced under the main popular systems, I got an option for Nikon cameras. Cosina 70-210 / 2.8-4 is a complete analog of the Vivitar Series 1 AF 70-210mm 1: 2.8-4.0 Apochromatic auto focus Zoom (just not to be confused with the model
Vivitar Series 1 AF 70-210mm 1: 2.8-4.0 VMC Macro Focusing Zoom).
I rarely see lenses with a focal length range of 70-210 mm and maximum aperture F / 2.8-4, usually the more popular combinations are 70 (80) -200 / 2,8 and 70-200 / 4. When using on camera Nikon D80 the aperture could only be opened up to F / 3but on Nikon D700 everything is as expected - F / 2.8. Most likely, this specific behavior of the lens is associated with not the best programming of the lens microprocessor, which I often see on old, and sometimes new lenses from third-party manufacturers.
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. JVI... 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.
The lens has a 'Full / Limit' focus limiter. In the 'Limit' position, focusing is available from infinity to 7 meters, or from 1.1 meters to 6 meters. Nicely I was surprised that in the 'Limit' position the lens has fast automatic focusing, but in the 'Full' position the time for scrolling the focusing ring by the camera motor from MDF to infinity and back is greatly increased.
When focusing, the front lens of the objective rotates and moves forward, with such a lens it is problematic to use special light filters: (. The focusing ring is rubberized and rotates 100 degrees in the 'Full' position, 45 degrees in the 'Limit' position.
Also, the lens has a macro mode, which becomes automatically available when using 210 mm focal length. In this position, the focus ring can rotate further than 1.1 meters, its total stroke is 180 degrees, and the maximum magnification ratio is 1: 2.5 X, which is very good for a zoom lens. When the focus ring is in the yellow macro mode, changing the focal length will not work. Auto focus also works in this mode, but its speed is slow.
Auto focusing with Cosina 70-210mm 1: 2.8-4 MC Macro lens available only when using him on cameras with built-in motor focusing. An exact and complete list of Nikon CZKs that support auto focus with 'AF' lenses can be found in the 'Auto focus on Nikon cameras'. 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). To control the value aperture of any modern Nikon camera automatically, you need to install the ring aperture to position F / 22. If this is not done, the 'fEE' error will appear on the camera display. For more details on the iris control ring, see Non-G Nikon Lenses.
Attention: Cosina 70-210mm 1: 2.8-4 MC Macro does not transmit focus distance values into the camera, which may give errors in exposure when shooting with flash in TTL auto modes. For Nikon cameras, the lens is an analog FX, AF, Non-d the lens.
Cosina 70-210 / 2.8-4 well assembled. The thread for the filters is metal, like most of the lens housing. The focus ring has a slight backlash. The lens uses a lens hood that can be set both in normal operating condition and in the transport position. In the last state, the lens hood completely blocks access to the focus ring.
When sighted in JVI it can be seen that the lens gives off a little yellow-green tint, which may be a problem when using the preset settings BB ('flash', 'cloudy', etc.). Auto white balance easily copes with this drawback, and the output is quite nice color rendering. The lens itself creates a very pleasant picture, but it's a pity that everything is very weak with sharpness at open apertures, and even strongly chromatite. With aperture down to f / 8, sharpness bounces back. In addition, Cosina 70-210 / 2.8-4 does not tolerate backlight well, while significantly losing contrast and filling the picture with sunbeams. Apparently, the vaunted 'MC' (Multi Coating) lettering is not enough for the lens to combat backlight.
