Nikon is introducing a new FX-format DSLR, the D610, although as far as features go, it is perhaps 98%, 99% the same as the entry-level D600, introduced 13 months ago in September, 2012: http://www.photo.net/nikon-camera-forum/00aofD Nikon USA has made it very clear that the D610 is the successor to the D600; i.e., the D600 will soon be officially discontinued, although some remaining stock will still be available new for a short while. Traditionally, Nikon probably would have called this a "D600S," indicating minor changes from the D600, but this time they choose to use a different model number D610. The D610 has a few minor improvements from the D600: Its maximum frame rate goes up to 6 frames/sec (fps), from the D600's 5.5 fps. The D610 has a new Quiet Continuous mode; it can capture in the quiet mode at 3 fps. The D610 has improved white balance, which can use face recognition, blue sky detection, etc. Otherwise, the D610 is still a 24MP FX body, with the same 39-AF-point Multi-CAM 4800 AF module, including 9 cross-type AF points among the 39. It uses the same MB-D12 optional battery pack/vertical grip and the same EN-EL15 battery. Nikon has made it very clear that there is a new shutter mechanism to support the new frame rate and quiet mode. To put it bluntly, there is little doubt that the D610 is introduced to separate itself from all the negative publicity from the oil/dust issue from the D600, and the original shutter mechanism seems to be the culprit. (That problem was first reported by Roger Cicala, the owner of LensRental.com: http://www.photo.net/nikon-camera-forum/00axxj) While some members here got into very stubborn oil/dust issues that require multiple repairs and even shutter replacements, my personal opinion is that most D600 are ok, but there is no doubt that there is a lot of bad publicity on that model. Personally, the disappointments on the D610 are: Nikon does not use the 51-point Multi-CAM 3500 AF module, which provides better AF point coverage on FX. There is still no separate AF-ON button, although there is clearly plenty of room for one. Otherwise, the D610 is mostly the same camera as the D600. In the US, the D610, body only, is $1999.95, $100 lower than the introductory price for the D600 a year ago. With the 24-85mm/f3.5-4.5 AF-S VR lens, the kit is $2599.95. There are additional kit options with lenses such as the 28-300mm AF-S VR, memory cards, and laptop bags. For those of you who want to save some money, remaining D600 bodies are now the "old" model, and you may be able to find discounts while supply lasts. Again, I think the D600 is still a fine camera, but if you get one, please make sure to check for any dust/oil issue on the sensor. If there are problems, get it replaced quickly.
