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
The rule of thumb is that focal length any lens used on an APSC format Sony camera must be multiplied by the crop factor (in the case of Sony - this is 1.5x) in order to determine is equivalent focal length for a full frame camera. In other words, a 50mm focal length used on an A6500 (with a 1.5x crop factor) will give you the equivalent field
85mm portrait lens. A short telephoto is typically the portrait photographer's favourite focal length - with a something around 56mm on a camera with an APS-C sensor or a 85mm on a full-frame
Finally, Olympus and Panasonic/Leica use a slightly different cropped format known as the Four Thirds system. The crop of the sensor varies a little between manufacturers as well. Most manufacturers' crop is smaller than a full frame sensor by a 1.6 ratio. But, Nikon's ratio is 1.5 and Olympus' ratio is 2.
It leverages its longer cropped focal length of 75mm with a more realistic depth to the elements in the photo, since it doesn’t distort the image like the 35mm. It becomes an ideal option for portraits at the cost of taking wide shots like a full frame 50mm lens could. 50mm vs 85mm
Unless qualified further "equivalent" focal length means the focal length one would need on a full frame camera in order to get the same field of view (or same magnification) as produced by the given lens on that other (smaller or larger format) sensor. As an example a 50 mm lens on APS-C has an "equivalent" focal length of 75 mm. The Bottom Line
