Komura fast 100, 105 and 135mm lenses - King of Ernostar

M42 Uniadapter Preset lenses.
For some reasons with highspeed short telephoto lenses I always loved preset lenses.
Possibly the shortest, and the most lightweight lenses in the 100mm f/2 range ever build.
Cameras: Spotmatic SP black
and SP-F chrome (highly recommended for users because of common battery size)
The lenses are of the same vintage (about 1968-73)
My first thought was the 105/2.0 and the 100/1.8 have just different beauty rings but they do differ in size more than 5mm. The color of coating is also different.







The 135/2 will follow soon...

Very Happy

Preset lenses are irresistible, especially the fast ones! I was shooting with my newly acquired Accura Supertel Tc 1:1.9 f=85mm (Nissin Optical Mfg.) today, and it definitely has its own character (swirly bokeh). Do you possibly know something about its optical layout?

That 1.9/85 Accura Supertel is by Nissin ?

Did they use "N.K.K." on their own branded stuff ?

Interesting. Maybe some other things are too.
