Canon 50mm f/1.8 EF II
This is a cheaply constructed plastic lens, which is also reflected in the low price. Sharpness is good (especially considering the price), but is suffers from some CA and flare. It has a five blade aperture and its bokeh is very harsh.
The AF is slow and noisy, and lacks the precision of its f/1.4 brother. No distance markings, and the manual focus ring is flimsy.
Some find its light weight attractive.
