As I wrote a few days ago, I only took one roll with the Contax II and
I have two samples lens wide open, one of them referred in the
previous message, it looks sharp, the other one is a bit blurred due
to the slow shutter speed but I like it due to the old colors, I need
to take more photographs with the lens to know if I agree or disagree
with you.
