I'm super excited about this lens! I'll buy it for whatever $ tag they put on it!
I've been studying MFTs and wow - great stuff! I have the new 8-15mm fisheye and the color, sharpness and punch blew me away when I took test shots. Simply stunning! After I took the shots I learned how to read MFT and yep - it's way up there. This new lens has similar MFTs so I know what to expect now, which is why i'm so pumped!
Edge/corner sharpness. The release says "crisp clear edges around the subject". Woohoo! - finally Canon are doing something about this horrible issue! I so hope they update their f/2.8 and f/4 wide angle zooms to improve edge-to-edge sharpness like the new 24-70 and new fisheye. The signs are there.
So they've updated the 70-200mm f/2.8 (I bought it) and it's sensational (in hindsight a 82mm would've been good!). Now they have updated the standard f/2.8 zoom. Next on the hitlist - Canon get your act together and bring out a decent f/2.8 wide angle zoom! (one that has a filter thread please!). It surely has to be in development!
PS. I was right about my earlier post about the switch being a zoom lock
PPS. I'm putting my 24-70, 24-105 and 100L macro on ebay as soon as I get this new lens.
