For completeness this page takes a quick look at the comparative performance of consumer zooms in the 20 to 135mm range.
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.
Consumer Zoom 20mm
Consumer Zoom 24mm
Consumer Zoom 28mm
Consumer Zoom 35mm
Consumer Zoom 50mm
Consumer Zoom 85mm
Consumer Zoom 100mm
Consumer Zoom 135mm
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.
