Canon EF 100mm F2.8 L IS USM Macro Review

Back in July, Canon took the distinctly unusual step of announcing a new technological development completely in isolation from any products. The subject was a novel 'Hybrid' optical image stabilization system designed to compensate for two distinct types of camera shake. You can read more about it here, but in essence the stabilizer is different from existing systems, which only detect and correct for changes in the angle the lens is pointing, by also compensating for vertical and horizontal shifts in the position of the lens caused by handshake. This has little benefit at long focus distances, but as the subject gets closer it becomes progressively more important, and in principle offers maximum benefit for macro shooting.

In September the company duly introduced the first lens to feature this new technology, and to no great surprise it turned out to be a 100mm macro. The EF 100mm F2.8 L IS USM Macro joins Canon's impressive short-telephoto lineup as a supplement to (rather than a replacement for) the existing EF 100mm F2.8 USM Macro, and at a significantly higher price. Alongside the latest and greatest IS technology it gains all the usual benefits associated with the premium 'L' badge, including robust, weathersealed build and the use of exotic glass for the correction of aberrations. The optical construction is of 15 elements in 12 groups, including a single ultra-low dispersion glass element, and the 1:1 maximum magnification is achieved at a minimum focus distance of 0.3m.

Canon makes some quite specific claims for the effectiveness of its new IS system, and it's worth looking at these in detail. The stabilizer is supposed to give a 4 stop advantage at longer focus distances, dropping to 3 stops at 0.5x magnification and 2 stops at full 1x magnification. The first of these specs is pretty much par for the course for Canon's current IS lenses, but even with the Hybrid system it's clear that the level of stabilization at close distances is expected to be relatively low (this despite Canon's publicity material claiming that it 'enables photographers to capture stunning close-up shots without the need for a tripod'). So the question potential buyers will surely be asking is whether the blend of features offered by the new lens is sufficiently compelling to justify buying it over the older, but well-regarded non-stabilized 100mm macro.

I love my Macro Photography, l had the Tamron 90mm superb lens for macro and portrait photography, but when l bought the new Canon 100 mm macro with the new hybrid IS. This lens is just superb. If you like your Macro photography and you have the cash buy one.
