EF 100-400mm f/4.5-5.6L IS USM telephoto zoom lensCanon EF 100-400mm
f/4.5-5.6L IS USM

Overview

Classic 'L' zoom lens. The push-pull zoom action may not be to everyone's taste, but the performance at longer focal lengths is excellent. The relatively ligh weight an IS make this a great hand held lens, particularly on a crop sensor body, where the 640mm (equiv.) field of view can be very handy.

EF 100-400mm f/4.5-5.6L IS USM telephoto lens 100mm mtf chart EF 100-400mm f/4.5-5.6L IS USM telephoto lens 400mm mtf chart

A quick guide to MTF charts (which only measure contrast and resolution. Canon's guide to their MTF charts)

Black lines reflect lens performance at widest aperture.
Blue lines show the performance at f/8

Thick lines indicate lens contrast
Thin lines indicate lens resolution

Dashed lines: Lens performance with meridional lines.
Solid lines: Lens performance with sagittal lines

Closer sagittal and meridional chart lines indicate more 'natural' out of focus areas.

Remember that MTF charts are good for comparing similar lenses, so comparing ones from the 14mm f2.8L and 300mm 2.8L won't tell you much at all, whilst comparing the EF14 2.8L with the EF14 2.8L II will show meaningful differences. Note that other manufacturers may have different ways of displaying such information that may or may not match up with the Canon figures.
