Some new Nikon D600 specs in addition to what I reported two week ago (new specs are on top, marked in bold):
- 39 AF points (with an option of 11 AF points)
- 5 fps (same as the D700, the D800 has 4fps)
- 2 SD card slots with Eye-fi support
- Build-in retouching images functionality
- Built-in flash with sync speed of 1/250s
- Two user settings: U1 and U2
- Fn button
- GPS
- HD video
- The sensor inside the D600 will probably be 24MP (made by Sony, modified by Nikon)
- The new camera will be marketed as an entry level full frame camera
- Auto DX crop mode
- In-camera RAW editor
- Built in time-lapse functionality
- Possibly with build-in HDR
- Possibly with integrated GPS
- New external battery grip
- To be released this summer
- The D600 will probably not have an internal AF motor, which means it will work only with AF-S lenses (just like the D3200 and D5100)
- The price of the D600 is rumored to be very low – maybe as low as $1500
- Announcement before Photokina (September 2012)
- One or more low-priced f/4 lenses will be announced with the D600. For example, Nikon recently filed a patent for a 24-70mm f/3.5-4.5 full frame lens which seems to be designed for a cheaper FX DSLR body
At that point I feel comfortable to raise the [NR] probability for the Nikon D600 to 60%. Some of the listed specs may still be inaccurate, but I think I got the most part correct.
