A full-frame digital SLR is a digital single-lens reflex camera fitted with an image sensor that is the same size as a 35 mm negative.[1][2] This is in contrast to cameras with smaller sensors, typically of a size equivalent to APS-C-size film, much smaller than a full 35 mm frame. As of 2007 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 Kodak DCS-100, also used a smaller sensor.
When a lens designed for a full frame is mounted on a smaller-than-full-frame camera, only the center of the imaging area is captured. The edges are cropped off, which has the effect of zooming in on the center section of the imaging area. The ratio of the size of the captured image to the size of the full-frame 35-mm 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.
Nikon, which introduced their first full frame camera, the D3, in 2007, refers to the format as the FX format, as opposed to the APS-C format, which they refer to as the DX format.SLR is a digital single-lens reflex camera fitted with an image sensor that is the same size as a 35 mm negative.[1][2] This is in contrast to cameras with smaller sensors, typically of a size equivalent to APS-C-size film, much smaller than a full 35 mm frame.
