MTO-11CA
10/1000 Telephoto Lens
Description:
The MTO-11CA 10/1000 Telephoto telescopic lens serves as an interchangeable
one for the Zenit SLR cameras, intended for black-and-white and color photography,
used to take close-ups of remote objects, inaccessible parts of terrain, landscapes,
architectural details and sports competitions, ideal for photographic hunting.
The MTO-11CA 10/1000 Telephoto Lens is furnished with a set of colour
filters, and supplied in a handy lether carrying case.
"CAUTION" these lenses may not work
on all 35mm cameras with built in flash or other protruding devices on the front.
The lens diameter at the mounting flange is 126 mm or 63 mm radius. Measure
your camera from the center of the lens mount to determine if any camera part
extends more than 4 mm in front of the mounting ring within this radius. See

M42 - K mount adapter
This lens mount adapter allows M42 Universal Screw Mount to fit onto a Pentax
K mount adapter. Although the lens will fit physically, automatic diaphragm,
auto-focusing, or any other functions will not operate correctly while using
this adapter. In this case "stop-down mode" will need to be used when metering
since the lens does not have the ability to have its aperture controlled by
the camera body.
