| Re: Planar vs. Sonnar vs. Planar |
Wait, are you saying your Sonnar is sharper in the corners wide open than it is at f5.6?? Mine certainly isn't Planar sharp at the edges, but it's not THAT bad. Certainly better than the Nokton 35/1.4 at the corners, FWIW, although both of them have field curvature, and focusing a little past infinity improves the corners.
Either way, if I need corner to corner sharpness, I shoot the ZM 35/2 (or maybe my new Contax G 45.) The Sonnar is for people shots and general "vibey-ness," for lack of a better term. Of course, at f5.6, I'm not totally opposed to shooting flat field subjects with it, and it should be mostly fine at my 13x19 print size, but there are certainly better options for that type of thing.
The C-Sonnar has what Zeiss calls "round" sharpness.
