![]() It, in turn, changes the surface area yet will still be referred to as a FF or ASP crop camera. This is not the "crop factor".ĮDIT: I'd like to add that digital cameras are capable of all sorts of different aspect ratios now which "crop" the sensor being used, anyway. Regarding surface area, yes, there is even more reduction.Īs a percentage of area, the APS-C only covers 44% of the full frame. 1 with ASP-C with a 35mm lens and a full frame with a 50mm lens, they would almost be seeing exactly the same thing. So a 34mm lens, x 1.5 = 50mm (actually 52.5, but I'm rounding it down. If you have a 50mm lens on a full frame camera but placed it on an APS-C camera, you would get a different (cropped) field of view. This is where the "crop factor" comes in.Īnd also relates to the field of view. There were even half frame cameras that used this film but would result in 18mm x 24mm frame sizes and would fit almost twice as many photos in one roll.ĪPS was also a film size and the classic, 3/2 ratio/format, had a size of 24mm x 16mm (roughly).įor APS film, the height (red side) of the film was/is 16mm. The camera determined the format/ratio but was always 24mm high. There are many various film and digital sensor sizes and formats.ġ35 film (also known as "full-frame") became the most used film in the 60s and the most common format was 3/2, meaning 36mm x 24mm frame size. Why "resulting in a sensor with 66% less area than a full-frame sensor-a rather substantial loss in sensor size"? Is its area (1/1.5)^2 = 0.44 of the area of a full frame sensor? Why "the sensor is 43% smaller in both width and height than a 35mm film cell"? In the example for a camera with a 1.5x crop factor, is its width (or height) 1/1.5=0.67 of the width (or height) of a full frame sensor? This is because the crop factor is applied to both the width The specifics depend on the camera brand, but the sensor size is generally around 23 mm x 15 mm. The crop factor of these cameras is 1, and this is known as Full. An APS-C camera, on the other hand, has a smaller sensor. Pricier digital SLRs are usually fitted with sensors that have the same size as 35mm film. This is the largest sensor size marketed to photography consumers. Less area than a full-frame sensor-a rather substantial loss in sensor A full-frame camera contains a sensor size equivalent to 35mm film (36 mm x 24 mm).
