12.1MP full-frame CMOS. No video — stills only. 9fps with AF tracking; 11fps without AF. 51-point Multi-CAM 3500FX AF system. EN-EL4a battery (11.1V, 2500mAh). 1,390g with battery and card. Nikon F full-frame (FX) mount. Dual CF card slots.
The D3 was Nikon's return to full-frame DSLR after years of DX crop: the full-frame sensor provided extended ISO range and natural perspective for photojournalism and sports. At 9fps with the new 51-point AF system, the D3 matched and in some metrics exceeded the Canon EOS 1D Mk III in sports performance. No video capability — DSLR video recording was not introduced until the D90 (2008) and D3S (2009).
On the used market the Nikon D3 is affordable as a vintage professional full-frame DSLR. Condition checks: shutter actuations (D3 rated for high cycles), EN-EL4a battery health, CF card slot condition. No video. Compatible with all Nikon F-mount FX and DX lenses.
