This is a record of using the KONICA M-HEXANON 28mm/F2.8, a wide lens for the Leica M, with a digital camera.

Photo example by LEICA M8

As described in detail in the technical report, the lens is constructed in a way to be close to a symmetrical shape based on a retrofocus structure.
I feel that this lens is sufficiently complete as a modern 28mm lens, with vivid colors and delicate rendering.
The camera used with this lens was the LEICAM8, which has an x1.33 APS-H size sensor, so it is not possible to evaluate the image quality of the peripheral areas. I wish I had an example with a full-size sensor, but I sold it before the introduction of the M9.

The exterior is black-based with red accents, which is not glamorous but gives the impression of quality and solidity.
The helicoid was also smooth, and although it did not have a focus lever, it was not difficult to use.
However, a focus lever was added to later 35mm/F2 lenses.


Leica M mount wide angle lens.
This is the widest angle lens among all KONICA M-mount lenses except for the 21-35 lens with two focal lengths.
The lens hood can be screwed on and rotated 120° to a position that does not interfere with the viewfinder. There is no device to fix it in place, so it may shift position in the camera back.
