Take photo by LEICA M8

In the case of 90mm focal length medium telephoto lenses and rangefinder cameras, focal lengths longer than 75mm have long been unpopular, and even now they are not very popular, and their prices are low.
In fact, when using the 90mm on the M Leica, it seems as if the viewfinder frame is mostly a meaningless area, a humble task to keep cropping a very small area in the center of the viewfinder.
The lens produces solid images from the widest aperture, which is common with other HEXANON lenses for the M-mount.
Also, the accuracy of the rangefinder linkage was not a problem even at the maximum aperture of f/2.8.
I purchased this lens when I was collecting KONICA M-HEXANON series lenses. However, I have released this lens without much use because I often use the CONTAX G SONNAR 90mm, which is a sonar-type lens, because it is easier to use.

A medium telephoto lens for the Leica M mount, the longest focal length of the six KONICA M-mount lenses.
The lens hood is a built-in type and is pulled out from the end of the lens barrel.
With an overall length of 69mm, it is a compact lens for a focal length of 90mm.
As described in detail in the Technical Report, this is a compact medium telephoto lens that uses the Ernostar type lens construction.
