In common lens adapters, cropping effect occurs in all APS-C digital cameras with 1.5x magnification. This adapter reduces focal length to 0.72x , to adjust the image size to near 1:1 so that the focal length of the image is close to actual focal length of the lens, e.g. 50mm x 1.5 x 0.72 = 54mm. For 4/3 sensors, crop factor is 1.44x.
