Review

Konica M Hexanon 50mm F2 is a standard lens released at the same time as Hexar RF in 1999.
In addition to this, 28mm and 90mm have also been released.

There is a detailed explanation of the lens in the technical report, but it has a Gaussian lens configuration with a hood built into the lens barrel, and the lens design is similar to the 4th generation Summicron M 50mm F2.

Hexanon 50mm and Summicron 50mm have similar lens designs, and the following are the characteristic differences between them.

The three front elements of the Hexanon have independent air surfaces.
The Summicron has three front lenses, the second and third of which are bonded together.

Although there is a difference of about 20 years between the two releases, it is interesting that they have almost the same design.

The reason why the lens configuration of the Hexanon 50mm is similar to that of the well-established Summicron Copy may be because the lens was designed to be conservative in anticipation of the bright 50mm F1.2 that would be released later.

The depiction is good from wide open aperture, and it can be used for both distant and close-up shots. I think it’s a passable lens with both front and back bokeh. However, in my personal lens collection, I couldn’t survive the fierce battle on the 50mm front, so I ended up trading it in when I bought something else.

It is the most compact lens in the Konica M lens series, and has a design that will not make you feel uncomfortable when wearing it, regardless of whether it is a film Leica or a digital Leica.
