No one except Pana and Oly has build AF lens for M4/3 nor do any of these companies who "joined" M4/3 plan to build AF lenses for M4/3. The manual focus lenses work anyway with adapter. I suggest you take your crap back to M4/3 forum.
+1both the lens and sensor are important
most cameras and lenses today are so good that it really up to the photographer when the sun is up.
Zeiss, CV, and others are all members of m43 now.With the NEX you can get some Leica, Zeiss ot voigtlander goodness and wait around, fingers crossed, for sony this year.
There is already a native Lecia lens (45mm macro) and a Voigtländer lens (25mm F/.95). Soon there will be Zeiss lenses too as well as Schneider-Kreuznach. Add Olympus and Panasonic, and that line up is amazing.
That makes 6 companies making m43 lenses..which it twice the total number of all NEX lenses.
