The past year has seen both Sony and Samsung unveil tiny interchangeable lens cameras designed to compete with the Micro Four Thirds units from Panasonic and Olympus, and now Nikon's getting in the game as well -- company president Makoto Kimura told Bloomberg Nikon will introduce a "new concept" mirrorless cameras with enhanced video functions as early as this year. (That sort of sounds like the Canon G11 competitor with DSLR tech Nikon was hinting at earlier this year, but we can't tell if they're the same.) Kimura says that Nikon is "intensively" focused on developing the new mirrorless product as part of a plan to increase SLR revenue -- Nikon's goal is to increase interchangeable lens camera sales a whopping 80 percent over the next three years. That's ambitious, but if Nikon can produce a tiny shooter with some of the D3S's low-light capabilities and the ability to accept even a subset of its modern family of lenses, we don't think it's out of the question. We'll see what happens.
