( September 2019)Ī crop factor (sometimes referred to as a " focal length multiplier" for comparing a proportionally scaled lens/image circle projection/sensor diameter) can be used to calculate the field of view in 35 mm terms from the actual focal length. Please help update this article to reflect recent events or newly available information. Sony: DT, E (APS-C if not designated FE).Most DSLR and third party lens manufacturers now make lenses specifically designed for APS-C cameras. However, as an APS-C sensor is smaller than a full-frame camera or Medium Format sensor, the opposite holds true, with larger sensors having less image noise and shallower depth of field than the APS-C sensor when taking a picture with the same focal length, f-stop, aperture, and ISO. This results in less image noise and shallower depth of field than a smaller sensor taking a picture with the same focal length, f-stop, aperture, and ISO. This is why each manufacturer offers a range of lenses designed for its format.Īn APS-C sensor is able to capture more total light than a smaller sensor with equivalent technology due to its larger size. Each variant results in a slightly different angle of view from lenses at the same focal length and overall a much narrower angle of view compared to 35 mm film. Because of this, devices with APS-C sensors are known as "cropped frame," especially when used in connection with lens mounts that are also used with sensors the size of 35 mm film: only part of the image produced by the lens is captured by the APS-C size sensor. Īll APS-C variants are considerably smaller than 35 mm standard film which measures 36×24 mm. Such sensors exist in many different variants depending on the manufacturer and camera model. APS-C size sensors are also used in a few digital rangefinders. Sensors approximating these dimensions are used in many digital single-lens reflex cameras (DSLRs), mirrorless interchangeable-lens cameras (MILCs), and a few large-sensor live-preview digital cameras. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm (0.980 in × 0.735 in) and Ø 31.11 mm field diameter.
