Nikon may be in the middle of developing a new camera series. These rumors are based on the release of the MB-D10 battery grip for the D300, an add-on that lets photographers both insert extra batteries and shoot with special portrait-ratio controls. Nikon grips have traditionally used a naming tied to a principal camera; the D200, for instance uses the MB-D200. The MB-D10 may thus be foreshadowing a namesake camera, which would likely be announced ahead of the Beijing Olympics in August or at Photokina in September.
If the Nikon D10 exists, it is expected to fall in between the D3 and the D300. This is based partly on the naming of Nikon’s low-end D40 and D50 SLRs, but also on Canon’s EOS-5D, which occupies a middle space between the high-end EOS-1D Mark III and mid-range EOS-40D. A D10 would therefore likely have a full-frame sensor, and a megapixel rating higher than the D300’s 12.3.
