Nikon D300S Specs and Screenshots Leaked

The D300 is Nikon’s top-level DX camera, meaning that, unless you opt for full frame, you won’t get a better camera. The D300 debuted alongside the flagship D3 back in 2007, and as the D3 has spawned the D3x, we’re not surprised to learn that there will be an upgraded D300.

Video will probably be the weird Motion JPEG found in the D90 and D5000. Here’s the relevant section:

Movie
Frame size (pixels) 1,280 x 720/24 fps, 640 x 424/24 fps, 320 x 216/24 fps
File format AVI
Compression format Motion-JPEG
Autofocus Contrast-detect AF on a desired point within a frame is possible (Tripod mode)
Audio Sound can be recorded via built-in or optional external microphone; sensitivity can be adjusted
Maximum length 5 min (1,280 x 720 pixels), 20 min (640 x 424, 320 x 216 pixels)

Interestingly, the sensor will be the same 12MP size of the current D300
