Hey folks, How useful is the 40mp high res mode? I've been looking for a mirrorless backup to my D800 and I've always like the micro 4/3 system (former EM5 User) - it seems by far the most mature compact system and I really like the more DSLR form factor of the EM5 (with grip) and EM1. However the hi-res mode has me intrigued! Part of some of my reluctance to pickup a CSC has been the drop from the 36mp of the D800 to the 16mp on Fuji and Olympus - I have looked at the Sony A7 (24mp/36mp) but I feel the systems aren't there yet. The 40mp hi res mode sounds like it could be a great solution to the problem of lower resolution but how usable is it? I do a lot of tripod based shooting (landscapes and architecture mainly) and from what I've read it sounds like the hires mode might be decent for that.
