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.
