I recently received a CV 35mm LTM f/1.7 and the advice that it is a good lens. I have been using an old Canon 35mm LTM f/2.0 (Black) with pretty good results. And I have the CV 35mm f/1.4 Nokton II. So why not compare them? I threw in an old '51 Jupiter-12. They are in order Canon, CV f/1.7, CV f/1.4, Jupiter-12 and all were shot Aperture Priority, AWB, Auto ISO in ascending f-stops: wide open, f/2.8, f/5.6 and f/11. The Jupiter-12 is f/2.8 so there are two of those. The camera was an M-9.
