Cement separation not affecting images
The 50/1.5 Sonnar with cement separation seems to be performing OK. It was raining when I tried it outside, i.e. no bright sun to test for flare, but otherwise test shots taken indoors and outdoors seem to come out ok (on a Kiev 4am, 400 film, no meter, "quick-and-dirty" shots).
On the 13.5 cm Nikkor lens, I tested the focus on my Kiev 4am as Vince suggested (candle light and scotch tape) and, amazingly, the film plane and rangefinder patch focus was achieved concurrently with the original(?) ~1mm brass shim in place. I am now half way through with a test roll, hoping it works 🙂
