Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras – Product Description:

Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR CamerasBring small things into full-sized view with the Canon EF 100mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The lens offers such features as a three-group floating system for exceptional close-up performance; a secondary diaphragm that blocks stray light at f/2.8, which increases contrast when shooting wide open; a ultra-sonic monitor (USM) that provides outstanding autofocusing speed at all focusing distances; a wide manual focusing ring with smooth action; and full-time manual focus even in AF mode. The first lens in its class to feature inner focusing, the lens carries a one-year warranty.

Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras – Review:

AN EXCELLENT LENS FOR THE BUDDING NATURE PHOTOGRAPHER

Prospective buyers of a macro lens for a Canon EOS system have a great first choice in this 100mm Macro. The extra length over a 50mm macro gives much better working distance (space between lens and subject) in the field, and EOS-compatible lenses by other manufacturers match poorly with accessories and are nowhere near as sharp.

Compared with the earlier Micro Motor 100mm Macro that Canon made (which I also own), the USM lens focuses *very* fast. The USM lens also can accept Tripod Collar B (by use of a small plastic adapter)–I recommend you buy the collar with the lens, as adjusting to a vertical composition with a tripod means repositioning everything. The front element is not recessed in the USM model, which makes lens cleaning easier than with its predecessor. And build quality is improved–the earlier model was prone to its switches breaking (could fix it yourself with the ordered part, but really annoying) and eventually the Micro Motor gearing gave out (no trouble so far with the USM ring motor). The USM model will work with Canon’s 2x teleconverter by interposing a 12mm extension tube, allowing 2x magnification with lots of working distance, though this is not nearly as nice a solution as the 180mm lens referenced below.

I will quibble with another reviewer–Canon does make sharper lenses, and sharpness compared with the earlier model is virtually the same. But this is still one of the sharpest lenses you can buy, and ergonomically a huge improvement over its predecessor.

Having said that, Canon now has an L-series 100mm macro that is a bit sharper and has better bokeh (out-of-focus highlights). A serious hobbyist might consider that lens, though it costs about 40% more on the street. I purchased the Canon EF 180mm f/3.5L Macro Lens less than a year ago, and am very impressed with its greater sharpness and working distance relative to this lens. If you work much with small critters, take a look at that lens before making a purchase.

If you are building up a set of lenses for outdoor/nature photography and you do occasional macrophotography, this might be the first or second lens to buy. If you work significantly at magnifications greater than 1:1, consider the Canon 65mm 1x-5x Macro zoom.
