From the Camera 35 magazine (December 1967/January 1968)

Among those who know anything about lenses for 35mm cameras, Hexanon Lenses rate very high indeed. Frankly, it is for basic reasons like this 21mm f/4 lens that Konica enjoys such a fine reputation. Another factor which is very important to some photographers is that in addition to the impressive lens performance, there is fully automatic operation. Don't look down your nose at the Hexanon mount because it is constructed of plastic... this helps in making the lens light and convenient to use. There is also an automatic override if you wish to use the lens manually. Obviously, no cutting corners here.

A very, very good ultra wide angle lens for the 1960s era. Works very well on modern digital cameras. I shot with it on a Sony A7 III (24 megapixels) and got a very good result – minimal distortion, you can reproduce drawings!
