Focal length, technically, is a physicap property of the lens, so that Sigma has a focal length of 56mm, but 99.99% of the time when we say 'focal length' we care about field of view. Because of the smaller sensor, a 56mm focal length lens will have the same field of view as an ~85mm lens on a full frame camera. Dalam hal ini, selain hanya ukuran sensor gambar, Anda juga perlu mempertimbangkan teknologi lain yang terlibat. Kamera APS-C kelas atas yang lebih baru, mungkin memiliki performa cahaya redup yang sama baiknya atau lebih baik daripada kamera full-frame kelas bawah yang dirilis beberapa tahun sebelumnya. EOS RP (full-frame) @ 35mm, f/4, 1/60 For example, an APS-C sensor has a crop factor of about 1.5, which means a 50mm lens on an APS-C camera will behave like a 75mm lens on a full-frame camera. Add your perspective These days, you have three main sensor sizes in most pro or semi-pro cameras on the market: full-frame, APS-C, and micro 4/3. In terms of sensor size, a full-frame sensor is quadruple the size of For example, the tiny 1/2.3″ sensor in Nikon’s P950 extracts an equivalent focal length of 2000mm out of a lens with a physical focal length of 357mm. Find out more about Focal Length. Yet, despite increasing ever-increasing megapixel counts, the potential image quality of small sensors is fundamentally limited. One of the biggest differences between full-frame sensors and APS-C sensors is the crop factor, as shown in the image above. The crop factor gives you a narrower field of view for the same focal length than a full-frame sensor would. APS-C sensors have a crop factor of 1.5x or 1.6x, while full-frame sensors have no crop factor. The focal length and field of view is the same for EF and EF-S lenses on the same camera. however, when reading a lens review that was made on a FF camera, note that the overall experience of that lens on a crop camera may be different (for example, I love the 70-200 on full frame, but rarely use it on my 7D as it gets "quite long" on that camera). Do you experience a crop factor with an APS-C camera even if you are using an APS-C lens? In this video, I compare the crop factor of a full-frame camera and 0Yuyz9e.
