It’s worth noting that your lens’ focal length output will be affected by the type of camera you choose and it’s sensor size (crop factor).
It’s worth noting that your lens’ focal length output will be affected by the type of camera you choose and it’s sensor size (crop factor). Lens length is measured based on a standard full frame camera. As APS-C and MFT cameras crop the frame, the original focal length is effectively multiplied by the crop factor.
