The lens is designed for a frame size of 18X24 mm, that is, half a frame. The first Chaika camera had a non-removable lens, the subsequent wide-angle Industar received a M39 threaded connection and its focal distance of 27.5 1. The I-69 is of great interest to owners of mirrorless system cameras Olympus and Panasonic. Since the above voiced cameras have a matrix that does not exceed half a frame.

The first attempts to put the lens on a camera with a large frame size were made back in the days of the film era, FED and Zorkiy showed eerie vignetting at the corners of the frame and a sad drop in resolution at the edges of the frame. With the advent of the Sony A7 mirrorless camera, attempts to put the lens on FF (full frame) were resumed, and Industar-69 was also successfully tested on mirrorless cameras with an APS-C matrix format (crop 1.5).

The design and ergonomics of the wide-angle pancake:
A thin lens - these are usually called pancakes, in fact it is not surprising - the optical scheme of the I-69 has only four elements. Most of the lens barrel is the focusing order ring. The diaphragm setting ring is located on the front, which is not very convenient.
