In this section plots are presented for the lenses and reference lenses in several focal length groups for maximum aperture and f8,10 and 30 lp/mm.  

The Canon MTF plots are computer models and do not include production tolerances. For comparative reasons each plot includes at least one L zoom, a wide range zoom and where applicable a EF-S zoom.

Generally there is a noticeable performance gap between the L zooms and the consumer zooms, even stopped down. The EF-S lens hold there own fairly well against the full frame consumer zooms but are outclassed in a few cases.

The EF 20-35mm showed good full frame average edge performance compared to the 17-40mm f4L.

Some of the lenses such as the 24-85mm and 28-90mm showed fairly good average performance.
