The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.

Some cameras use larger sensor including, at the high end, a full-frame sensor.

This is part of the reason that professional cameras (with full-frame sensors) are astronomically expensive compared to 1.6x crop sensors or much smaller point-and-shoot cameras.

It features the 24.3MP effective 35mm full-frame sensor, with the normal sensor range of ISO 100-32000.

Some professional DSLRs use full-frame sensors, equal to the size of a frame of 35 mm film.

When full-frame sensors were first introduced, production costs could exceed twenty times the cost of an APS-C sensor.

Newer photolithography equipment now allows single-pass exposures for full-frame sensors, although other size-related production constraints remain much the same.

Additionally, the full-frame sensor requires three separate exposures during the photolithography stage, tripling the number of masks and exposure processes.

The D700's full-frame sensor allows the use of non-DX F-mount lenses to their fullest advantage, with no crop factor.

This sensor is 56% larger than a full-frame sensor.
