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 The most popular large camera sensor sizes are Full-frame, APS-C, and Micro Four Thirds. Whereas smaller cameras, super-zooms, and smartphones tend to use much smaller sensor sizes of 1″, 1/1.7″, and 1/2.3″. Popular Large Camera Sensors. Full-Frame is the largest of the three most popular large camera sensors. Well, the first answer is that the focal length on the 36×24 camera is double the focal length of the m4/3 camera (50mm vs 25mm) so the full frame camera requires more light to get the same exposure on its larger sensor. That’s why the virtual aperture is larger. This also helps us explain why we have f-stop numbers in the first place. However, since a longer focal length is needed on FF to deliver the same angle of view as on APS-C, you'll generally have an easier time getting background blur on FF. I.e. a 24mm has less depth of field than a 16mm, yet they both deliver the same field of view when mounted on FF and APS-C, respectively. Adam. In practice, it is easier to talk in terms of equivalent focal lengths, EFL. This is the focal length needed to give the same field of view using a full frame sensor. For example, a 50mm lens on Canon APS-C camera will give a field of view equivalent to 80 mm lens on a full frame camera. The calculation is simple: EFL=FL*CP Itulah mengapa, kamera APS-C dan MFT tepi bingkainya terpotong, sedangkan kamera full-frame tidak. Hasil akhir focal length pada tipe APS-C dan MFT berasal dari focal length asli yang dikalikan dengan crop factor. Misalnya, kita memasang lensa 35mm pada kamera MFT yang memiliki crop factor 2x. Otomatis, focal length-nya berubah menjadi 70mm. 4) Lens Focal Length vs Equivalent Focal Length. Whether you mount a full-frame lens on a full-frame, APS-C, Micro Four Thirds or 1″ CX camera, the physical properties of the same lens never change – its focal length and aperture stay constant. This makes sense, as the only variable that is changing is the sensor. Full-Frame vs APS-C Sensors. Focal Length Differences. How Focal Length is Measured; Full-Frame vs. APS-C Images; Cropped Full-Frame vs. APS-C Images; Crop Factor and Wide Angle Lenses; Body Size Differences; Megapixel and Image Quality Differences. Advantages of Larger Full-Frame Pixels; Comparing Megapixels in Full-Frame vs APS-C Sensor 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 Micro Four Thirds Canon APS-C Nikon APS-C APS-H Cropped Medium Format Medium Format sensor, is equivalent to a 157.5 mm f/ 2.1 lens. 6mf5tRe.
