I was testing some of my vintage Rolex dials for radioactivity with a dosimeter. Out of curiosity, I pulled out some of my rangefinder lenses and tested them. I had one collapsible 50mm Summicron that I was almost positive was radioactive but it was not. So then I tried the 35mm f1.5 Canon and...

Noticed some of these going cheap on Evilbay. Anyone tried one? Any good? Or are they garbage? I read that they are similar to the Laowa 15mm f4 Macros but without the Shift capability.

I was trying the new adapter that came in yesterday and decided to take the CV 15mm f4.5 lens for a walk at night. The images were all too noisy. I'm too inexperienced with the camera and had the settings poorly selected by mistake. These were captured with as high as ISO 25,000... As I said...
