It's very doubtful statement. Actually for me it sounds like a pure BS, sorry
I only saw clear advantage at WA (18, 21)
I don't think the 25 f2.8 is better than FA* 24 (a friend of mine has a very good copy which is sharp at infinity from f4 across the frame).
For me the 31Ltd is better than 28 f2: I tried the CZ, I prefer the 31Ltd.
IMO CZ 50 just doesn't worth it's price. I will choose A 50 f1.2 without a doubt, as well as I prefer A* 85, FA* 85 and 77Ltd over the CZ 85 ZK. The latter is weak portrait performer. IMO they are the weakest with samyang 85 nowdays within other 85 f1.4s
Well, the CZ 100 is slightly better than DFA 100.
Pentax doesn't have 135 nowdays, but I don't find the alpha CZ 135 to be good portrait performer again. For example, I will choose canon's 135L every time.
