Additional information:

The Meteor-5-1 17-69 mm f/ 1.9 (Russian: Метеор) is a zoom lens for Krasnogorsk-2 and Krasnogorsk-3 movie cameras. The lens came in variants with both the unique Krasnogorsk bayonet mount and the M42x1 mount (flange focal distance - 45.5 mm)

The optical scheme of the lens includes 16 elements. Four elements make the principal lens; 12 elements in 5 groups are a part of the variable magnification and focusing system. (see the scheme) Focal length is changed by moving elements 2 and 4, whereas elements 3 and 5 are used to correct violations of bundle of rays parallelism. Front positive element 1 is used for focusing at finite distances from 1 m to infinity. The element is manually operated.

The Meteor-5-1 lens is designed for a 7.45x10.05mm frame size. Rear focal distance, i.e. distance from the rear element to the light detector, film or sensor, is approx. 15 mm. So the lens cannot be mounted on SLR cameras!!! Bold type and exclamation marks are used here for the users who can't read and who keep on asking how to mount this lens on a Canon.

Image circle diameter when focusing to infinity and with the focal length of 17 mm is approx. 15 mm, and 18 mm with the focal length of 69 mm.

Sensor diagonal (approx.):

APS-C - 30 mm

4/3 - 22 mm

Nikon CX - 16 mm

So, in order to achieve good performance the lens should be used on Nikon 1 cameras: Nikon J1, Nikon V1. With 4/3 and APS-C cameras, the lens may be used for 1.5-2x digital zoom video shooting. Equivalent focal length on Sony NEX cameras is approx. 50 - 207 mm.
