The crop factor is meant to inform the photographer how a lens would behave in its field of view. Use the handy cheat sheet above to see this all for yourself. This can be measured across the diagonal, vertical or horizontal of the frame, although you don’t need to worry too much about the figures here knowing the focal length is enough.Īs a general rule, as the angle of view gets wider (and the number becomes larger), your focal length gets shorter and you can fit more into the frame. and you use a full frame camera with 24mm wide angle lens and an. Except extreme wide angle landscapes and. So what actually happens when you change focal length? As the diagrams in the cheat sheet above shows, the angle of view changes so that you can accommodate more or less of the scene. But not many have ever considered using a camera with a crop sensor for that goal. This is really where full frame cameras shine, wide angle photography. Most manufacturers' crop is smaller than a full frame sensor. Disadvantage of Crop sensor cameras: Less wide angle. The crop of the sensor varies a little between manufacturers as well. If the lens has two, such as the 18-55mm lens mentioned above, then you will be able to use these two focal lengths and everything in between. Its full frame cameras go under the moniker of 'FX,' while its cropped frame cameras are known as 'DX.' Finally, Olympus and Panasonic/Leica use a slightly different cropped format known as the Four Thirds system. If there is only one figure in the title, say 50mm or 90mm, then the lens simply offers one focal length. In contrast to a full frame, a crop sensor is smaller and lighter, making them less expensive. ![]() Long telephoto: 300mm on full frame, 200mm on APS-C, or 150mm on MFT camera (Image credit: Chris George)
