There are virtually no criticisms of this lens that we can come up with! The build is a little short of L quality, but is still well built. The optical performance is first class with no nasty or disappointing surprises and as for the handling, it's a pleasure to use.

Good build quality; Very good optical performance; Nice handling with no extending front element

A little pricey; but you get what you pay fr; Still no hood included in the price

The Canon EF 100mm f/2.8 is an excellent medium-small lens, intended to be used for Macro photography. With its 1:1 reproduction ratio, it is capable of focusing at objects of all sizes. It is a versatile lens with great ergonomics and delivers amazing results.

Very sharp and fast/accurate AF. Focusing is very silent too. The focusing ring has a smooth feel to it, but somehow feels a bit too loose (imo only). The build quality is very good despite the material used. Feels solid but light for its size. Only gripe is that there is no Tripod Ring included....

Sharp; Fast and accurate AF; Lightweight without feeling cheap

No Tripod ring; HIS (regular IS would have sufficed

A 3-group floating system results in excellent delineation at all focusing distances. Ring USM for silent and high-speed AF, and full-time manual focusing also provided.

Canon's EF 100mm f2.8 Macro is a close-up lens which will work on both cropped and full-frame bodies. The maximum magnification is 1x, allowing you to reproduce subjects at actual size on the frame for excellent close-ups, while the f2.8 aperture enables blurred backgrounds.

Canon EF 100mm f/2.8L IS USM is the newest addition to the manufacturer's lineup of macro lenses, and is the second 'Pro' grade (or 'L') classified macro lens besides the EF 180mm f/3.5L Macro USM.

When it comes to macro photography lenses, the Canon's offer is more modest than e.g. the offer of Sigma. It doesn't mean, though, that we have no choice at all. For full frame bodies you can use a Canon 50 mm f/2.5 EF Macro, a Canon 100 mm f/2.8 EF USM Macro and a Canon 180 mm f/3.5L EF USM Macro.

excellent image quality in the frame centre and at the frame edge at all apertures; negligible chromatic aberration; distortion at practically zero level; very low coma; moderate astigmatism; silent and relatively quick autofocus; good build quality

autofocus could have been more accurate
