I had occasion to do a little bit of pixel peeping the other day comparing the outside corners of the CV-40, with my newly purchased CV-35 (Ultron II). The 40mm Heliar was a fair bit sharper than the 35mm Ultron. This was done on an M11. Indeed, the Heliar was even sharper than the 50mm Summicron (v5) as well. Beyond the discussion on whether you even need to pixel peep at all, anyone else find this too?
