Nikon Announces J1 and V1 Mirrorless Cameras and New Lens System. Nikon is steadily building the second smallest interchangeable lens camera system. I mean, is it really something to strive for to be the eternal second? Nikon claims to be the smallest, but the Pentax Q is actually a bit smaller. Oh, and Nikon only achieves this small size by using chips below m4/3 - with a 2.7x crop factor, Nikon no longer has to worry about the usually terrible bokeh of Nikon - you can't see much of it anyway there (okay, it's a bit better than the 5.7x "crop factor" of the Pentax Q system - but it's only the second smallest). If this is Nikon's big move, the big answer to the EVIL market, well.
