Nikon FX format : ウィキペディア英語版
Full-frame digital SLR

The term Full Frame is used by D-SLR users as a short-hand for an image sensor which is the same size as 35mm format (36×24 mm) film
.
Historically, 35 mm was considered a small film format compared with medium format, large format and even larger.
This is in contrast to cameras with smaller sensors (for instance, those with a size equivalent to APS-C-size film), much smaller than a full 35 mm frame. Currently, the majority of digital cameras, both compact and SLR models, use a smaller-than-35 mm frame, as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100, also used a smaller sensor. Kodak states that 35mm film has the equivalent of 6K resolution according to a Senior Vice President of IMAX.
==Use of 35 mm film-camera lenses==
If the lens mounts are compatible, many lenses, including manual-focus models, designed for 35 mm cameras can be mounted on DSLR cameras. When a lens designed for a full-frame camera, whether film or digital, is mounted on a DSLR with a smaller sensor size, only the center of the lens's image circle is captured. The edges are cropped off, which is equivalent to zooming in on the center section of the imaging area. The ratio of the size of the full-frame 35 mm format to the size of the smaller format is known as the "crop factor" or "focal-length multiplier", and is typically in the range 1.3–2.0 for non-full-frame digital SLRs.
