In nearly 40 years now of photographic habit, do you know how many "new" cameras I'v seen? TONS. It's a gimmick, some will want one and when the next "new" image-thingy comes along it's going into the kitchen drawer with the rest of the washed up tech toys. No camera ever has been a "threat" to professional photographers. It's the person squeezing he button that counts. You still have to know how and more importantly when to do that. Nikon has this, Canon, makes that, Polaroid, Yashica, Minolta, Kyocera, Sigma yada, yada, yada.
Some research.. try anything on Foveon cameras.. I think they are called doorstops now.. Carver Mead is a brilliant man. But why did Canon and Nikon pass on the fantastic new chip?? I actually went to a symposium given by Dr. Mead on the chip and early cameras. It was very exciting. Then they eventually sold to Sigma..
There are many who are making a comparison between Lytro and Foveon.. I guess we will see.
