I have both the 40mm Summicron and the CV 40 2.8. The CV is sharper if that matters but you really have to look for it. In normal pics I cannot tell much difference. I also have the 40 1.2 and that is great too.
I would say the biggest advantage about getting the CV 40 2.8 is the flare resistance and it will not be beat up. Have you ever seen a 40 Cron that does not have a lot of 'patina'? Biggest disadvantage is the handling is much worse than the 40 Cron.
Thanks. Yes, Cron is very prone to flare and I agree that Heliar 40/2.8 seems better choice... but I am worried about field curvature wavy towards infinity - from Fred test - which is improtant for landsape. Same issue has CV 40/1.2 + it's quite big.
