How does sensor size affect your photo? Well it’s all about crop factor. If you mount a 100mm lens on a full frame camera it captures a 100mm image. If you mount a 100mm lens on an APS-C camera, it crops the frame and the photo looks zoomed in, as if you took the photo on a 150mm lens. And if you mount a 100mm lens on a MFT camera, it will crop it as if you took the photo on a 200mm lens. This crop factor also affects your lens’ focal length, but more on this in the next section.
