Verdict

The Canon EF 100mm f/2.8 USM macro may not have the shiny reputation of an L grade lens but it's a great performer nonetheless. It provides sharp images straight from f/2.8 all the way down to f/16 and neither distortions nor lateral CAs are something to worry about. It produces some pronounced vignetting at f/2.8 but within the full format test scope it's actually better than most here. The amount of LoCAs (bokeh fringing) is comparatively moderate even at f/2.8. The quality of the bokeh (out-of-focus blur) is pretty good although not perfect.

The Canon lens features a true IF (internal focusing) mechanism so its physical length remains constant regardless of the focus setting - in terms of long term durability this is clearly a superior approach compared to the usual extension system used in third party alternatives. The principal build quality leaves also nothing to be desired for a lens in this class. The implementation of the USM (ultrasonic AF) is excellent - compared to conventional macro lenses in this range it is a speed daemon here and a near silent one.

Regarding its performance characteristic in this full format scope it is a steal for the money and as good as the much more expensive Canon EF 100mm f/2.8 USM L IS - minus image stabilization and a slightly less impressive build quality.
