A lovely Carl Zeiss Jena 50mm f/1.8 Pancolar in M42 mount arrived a couple of days ago. I have not yet had a chance to shoot it, certainly not to test it. But I did mount it on my Sony A7Sii a few minutes ago and shot one of my test subjects, my Lucas plushie.
The capture was made wide open and the background blur is evident in the shot. The lens is nicely sharp wide open and I think the background blur (bokeh) is very nice for this camera to subject distance. It will be fun to play with this East German lens and I will have to make a point of carrying the A7Sii and this lens (and maybe another) on walkies.
This is fun. Life is good.
