![]() Full-frame sensors are by far the largest. Compared to a Super 35mm sensor, a full-frame sensor has over twice the surface area while providing a wider angle of view and shallower depth of eld. To do a conversion from APS-C focal length to its 35mm full frame equivalent focal length, you take the focal length of the lens and multiply it by the crop factor of the sensor. What is Full-Frame A full-frame sensor is most simply dened by its sheer size 36mm by 24mm and the distinctive look it makes possible. You can use the crop factor of a sensor to do a focal length conversion from APS-C to full frame and vice versa. Micro four thirds sensors from the likes of Olympus and Panasonic have a diagonal length which are 2.0x smaller than a 35mm full-frame sensor. Similarly, APS-C cameras from Nikon, Sony, Fuji and Pentax have a diagonal length that is 1.53x smaller than a 35mm full-frame sensor. So a Canon APS-C sensor has a diagonal length that is 1.62x smaller than a 35mm full-frame sensor. The crop factor is calculated by comparing the diagonal length of a crop sensor to the diagonal length of a 35mm full-frame sensor. This way you’ll know whether they are talking about the full frame equivalent focal length or just the focal length of the lens without a crop factor applied. This is because the crop factor on a Canon APS-C camera is about 1.6x which means that a 50mm lens actually looks more like 80mm if it were on a full-frame sensor.Īlways pay attention when someone is recommending lenses to you. While a Canon APS-C sensor measures 22.2 x 14.8 mm, the offerings from Sony, Pentax, Fujifilm and Nikon (DX) vary from 23.5 x 15.6 mm to 23.7 x 15.6 mm. If you are listening to lens recommendations from another photographer and they are using a full-frame sensor then if they say that an 80mm lens is perfect for a specific purpose, then they mean 80mm.īut if someone else is using a Canon APS-C sensor camera they might say that a 50mm lens is perfect for that same purpose instead. Knowing the full frame equivalent focal length of your lens and camera combo can be very important. Why Does 35mm Equivalent Focal Length Matter? ![]() This crop factor calculator will let you see what a lens will look like on your camera if the lens was on a 35mm full-frame sensor camera instead of a crop sensor camera.
