Meet the Nikon D810 36.3 MP DSLR: a high-end camera capable of capturing amazing stills and video. It has a 30% faster EXPEED 4 image processing engine and a 36.3 MP FX-format CMOS sensor without an OLPF. The camera offers fast frame rates, in-camera editing features, and noise-free images from ISO 64 to ISO 12,800. You will be able to move between dark and light scenes without any frame-rate adjustment thanks to its ISO Auto Adjust.
The D810 camera can capture video at 5 fps at full resolution and in 5:4 crop mode, 6 fps in 1:2 crop mode and 7 fps in DX-crop mode. It is fully capable of capturing amazing timelapse videos. The bad news? This is not cheap.
