Super CCD: Standard DX size: 23.0 x 15.5 mm
Resolution: 4,256 x 2,848 pixels. Makes a 2.5 MB JPG at the normal setting. Also 2,304 x 1,536 and 1,440 x 960 settings.
Formats: JPG and RAW. JPGs come in NORMAL and FINE. RAW comes in two sizes depending on the dynamic range selected.
ISO 100 - 1,600
Lenses: Nikon mount.
Shutter: B, 30 sec. to 1/4,000.
Frame Rate: 2.5FPS; 1.4 FPS in wide dynamic range mode.
Buffer: 12/7 frames JPG/RAW; 6/3 frames in wide dynamic range mode.
Flash Sync: 1/180, pretty bad. Pro DSLRS and even the D70s and D50 are 1/500. This is the maximum speed you may use any time the flash is on. More here.
Flash Control: Nikon's crummy old d-TTL, not Nikon's latest and far superior i-TTL. Sure, it works with the newest SB-600 and SB-800 flashes, but only because those flashes are backwards compatible with older cameras using the inconsistent d-TTL system.
Memory: Takes standard CF and microdrives, also xD.
Power: 4 - AA cells. 4 - Ni-MH and charger included. Only rated for a few hundred shots per charge, compared to the modern Nikon D70/D70s/D50/D2H/D2x which give a thousand or more shots per charge.
Size: 5.8 x 5.3 x 3.1" ( 148 x 135 x 78 mm)
