Crop Factor Calculator. Get the full-frame (35mm) equivalent focal length and aperture for different sensor sizes. Just enter the focal length and maximum aperture of your lens and then choose a sensor size. My mm f/ lens, on a sensor, is equivalent to a 157.5mm f/2.1 lens. The crop factor for that sensor is 1.5x.
Field of View in Full frame vs. Crop Sensor Cameras [Includes photo comparison]. When photographers are interested in buying a full frame camera for the first.
An 17mm lens (APS-C or Full frame) on an APS-C body have a similar field of view to a 27mm lens on a full frame body. That doesn't mean that it is a 27mm, there is no real conversion. Focal length is an optical property and it's a bit more complicated than saying that the body "converts" the focal length. People will use "equivalent focal So an 80mm f/2.8 lens on a full-frame camera would have the same angle of view and light-gathering ability as a 50mm f/1.8 on an M5. So what? Similarly, the full-frame equivalent of a 32mm f/1.4 would be a 51mm f/2.2. So what? The Canon APS-C equivalent of a 50mm f/1.8 lens on full frame would be a 31mm f/1.1. So what?APS-C (aka ‘Crop’ sensor) The smaller size of the APS-C CMOS sensors means the camera body is also smaller than a full-frame option. It also results in lower cost while still delivering superb image and video quality. The crop factor of APS-C is a great advantage when using telephoto lenses. A 400mm lens on a full-frame body has a 400mm. 194 285 465 288 403 166 490 202
