This (very) vintage lens came to me a couple of weeks ago. It is from an Asahi-Kogaku rangefinder camera, probably made in the 1950s. I had to order a M37/M42 adapter so I could mount the lens. Then I got busy with field work and did not take time to shoot it.
Well, I decided to reprovision my stock, so I took The Girl and we drove down to Aloha Liquor. She waited while I did a little shopping. Then I made this capture of the store front.
The lens is certainly sharp at f/8. The colors are not quite as nice as the Hexanon 40mm f/1.8 produces. But they are good.
I made a second capture in black and white, below, of my Lucas plushie. This one was shot wide open (f/2.4). It is also quite sharp and there is a hint of swirly bokeh in the background. It looks like this lens will also produce some soap bubble bokeh balls as well. I need to play with it some more.
One more thing — this lens is heavy. There is a lot of metal in the lens.
