Full-frame photography used to be the preserve of professional photographers, but SLRs like the Canon 6D and Nikon D610 have made it a more realistic proposition for amateur and enthusiast photographers. Nikon's latest full-frame camera, the D750 sits above the D610 and the Nikon D810 in the company's range, giving enthusiasts another model to choose from. At the heart of the D750 is a newly designed 24.3-million-pixel CMOS sensor and a Expeed 4 processing engine. Unlike the 36Mp D810, the new camera has an anti-aliasing filter over the sensor.This sensor and processor combination enables a native sensitivity range of ISO 100-12,800 with extension settings taking this to ISO 50-51,200. It's also possible to shoot at up to 6.5 frames per second (fps) and record Full HD video at up to 60p. While 6.5fps is a fair rate, some sports photographers may have been hoping for something a bit higher, perhaps 8fps or more.Enthusiast videographers will also appreciate the stereo microphone and headphone ports along with the ability to fine-tune audio levels in isolation before and during recording.
