Originally posted by JayR I have the 50 F1.4, bought as an all-rounder but with portraiture in mind also... but im itching to compare the FA43ltd and DA*55 image qualities.
The biggest difference is 12mm and highlight discs in OOF. FA43 can be forced to produce some nasty things if you try, but the DA* with it's rounded aperture blades is great in this respect. They are both very sharp, and very contrasty from wide open. The DA* may be ever so slightly warmer to the red/orange side, while the FA43 is bit more yellow. Both of them can produce some harsh OOF rendering at certain conditions (I'd say FA50/1.4 is the same, K50/1.2 beats them all).
If I'd have to pick... well depends what would be in my bag. 43 is great match with 24 and 77, while 55 goes perfectly with 31 + 85.... truth to be said, on APSC 43 is too close to 31 IMO, but it's my only AF 50ish lens so I'm keeping it...
