Yes, I agree. I bought an old Summar and Zorki 4K a few months ago. Not the lens to use wide-open, but in its range it is very nice. It's sharper than I expected based on what I've read, might have the best bokeh of any lens I own, and certainly has the most recognizable signature. The 3D quality of this lens also stands out. A fun lens, and a fun kit.
Nice pictures by the way. Thanks for posting.
