Hi,

I own Canon gear: 7D, Tokina 11-16/2.8, Sigma 17-50 EX OS/2.8, Canon 85/1.8, Canon 70-200 L IS /4. All of this lenses get good reviews here. I shoot mostly in Aperture priority, raw mode.

But this gear is too heavy, and do not enjoy to carry it as I did before, especially for trekking.



So I am thinking about switching to another system offering still good IQ.



The Sony Nex 5 looks very nice, but when I read the reviews out there, I wonder if they are any sharp and quite light wide angle lens on this mount: for nice landscape photograph, I expect a lens to be sharp on the corner as well. I want something much lighter than my Tokina 11-16!



I am also looking at the m4/3, but fear a drop in IQ (~1 stop in high iso?) and even closer sharp aperture range than on my 7D (between the blur open and diffraction). The last G3 looks not bad however, I should try it.

According to the reviews here, the Olympus 9-18 seems a good compromise.



Or should I simply buy a P&S, like a Canon G12 where I could still work with raw format? Actually, I really wonder about the picture quality (especially on the border) in such a compact camera compared to any light wide angle lens on NEX or m43. Any clue?



EDIT: after reading http://forums.dpreview.com/forums/readfl...749&page=3 and http://www.luminous-landscape.com/review...port.shtml, I think I will forget the NEX serie which does not seems to be built for photograph enthusiasts but P&S users/beginners (User Interface, and missing light and fast lenses)
