Our friends over at PopPhoto got a look at the new Nikon J1 and V1, Nikon's first forays into mirrorless cameras. The big benefit of mirrorless cameras is a huge reduction in size from DSLRs--almost as small as point-and-shoots--with, theoretically, not a huge drop-down in image quality (we loved, for example, Sony's NEX-5, a similar idea). What's especially great about these Nikons is that there will be an adapter available so that you can use any F-Mount (Nikon's 35mm SLR mount) lens, so you won't have to buy a ton of new glass if you're already a Nikon user. Check out PopPhoto to see impressions and a full run-down of the new cameras. [PopPhoto]
