Re: SEL20F28 impresses and puzzles at the same time

I feel the need to concur a little bit (although not the "this is totally useless!" tone) with 007peter in asking about uncorrected images (although I will also remember to apply this in an egalitarian fashion, esp. when we get to talking about correction-needy m43 lenses).

Aside from the blurred 2-3% extreme corners, I feel that weakness of the SEL16F28 is its progressively worse CA from the center of the frame to outwards.  I am very curious whether this might have been improved with the SEL20F28... but that does require an uncorrected image.
