Description: Full-Frame and Crop refer to different size image sensors in digital cameras. "Full-frame" sensors are the same size as traditional 35mm film cameras, 24x36mm. "Crop" [frame] cameras/sensors include multiple sensor sizes, all smaller than full-frame. The two most common crops are APS-C and Micro Four Thirds. These smaller sensors represent an approximately 1.5x or 2x crop of any full-frame lens that is mounted on a full-frame sensor/camera. For example, a 50mm lens on full-frame will appear to be a 75mm, or 1.5x cropped image, on an APS-C camera.
Full Frame VS Crop
full frame versus crop
Full-frame versus crop is one of the most-discussed subjects in digital photography, for various reasons. Basically, larger sensor sizes are usually capable of producing slightly better image quality, and some specialized lenses are only available in a full-frame format. Crop-sensor cameras of all kinds are also highly capable, though, and have a vast array of different lenses available. In short, there is a wide variety of digital cameras and lenses available to suit your needs (and budget) as a photographer.
