Now the calculator is an APS-C focal length calculator. Select the Sony APS-C crop factor with a value of 1.53x from the list of sensor sizes. You have an APS-C camera with a crop factor of 1.53x (a super 35 crop factor), and you want to buy a lens that will give the same image as a 50mm f/4 full-frame lens. Let's look at a common problem when choosing lenses for crop sensor cameras. The calculator will apply the crop factor and tell you the focal length and f-stop in terms of 35mm full-frame equivalents.Īs with most Omni calculators, it also works backward. You can then input the focal length of your camera's lens and the aperture f-stop you are interested in using. An example image will appear when you do this, showing how much smaller or larger your sensor is compared to the standard full-frame sensor. The first thing to do is to select your camera's sensor size from the list of sensor sizes. We can see how lenses designed for full-frame digital sensors or 35mm film will produce images on different sized sensors when we know the crop factor. These cameras have sensors or film larger than the 35mm full-frame size, so the crop factor is less than 1. You can also get medium and large format cameras, which our crop factor calculator also supports.
