Compact and light, with an 80mm equivalent focal length on Canon’s APS-C bodies, the lens is about 1/8-inch shorter than the previous 50mm f/1.8. In fact, it’s Canon’s most compact 50mm ever, and also smaller than the Nikon 50mm f/1.8G (tested in our September 2011 issue), Pentax DA 50mm f/1.8 (February 2013), and Sony 50mm f/1.8 DT (October 2009). It also produces attractive bokeh with superb subject sharpness thanks to a new seven-blade circular aperture. Its predecessor had a five blade diaphragm, non-circular in shape. As a result, defocused specular highlights were not round, but pentagon-shaped.
