When the slightest disturbance can ruin a perfectly prepared live shot, the superb speed and silent autofocus of the USM motor paired with the 100mm focal length ensures you achieve the best results, whilst having enough distance so as not startle your subject. This gives you more flexibility to eliminate natural camera shake and to respond to your subject if it moves or changes position, ensuring crisp images when shooting macro subjects. Usually macro photography requires a steady tripod, however the new Hybrid IS helps to eliminate angular and shift camera shake. Shift-based shake occurs when a camera moves parallel to the image sensor scene, this is significantly more pronounced in macro photography. While many Canon lenses have Image Stabilizer (IS) capable of regulating camera shake when working hand-held, this lens features a groundbreaking Hybrid Image Stabilizer system to counteract regular angular shake and lateral shift-shake which is exaggerated when shooting extreme close-ups. This versatile lens gives great results in portrait work and handheld movie-making, thanks to its ability to achieve a shallow depth of field with beautiful bokeh, along with built-in Hybrid Image Stabilization and lightweight design. The picture below illustrates the lens's angle of view on full frame and APS-C DSLRs (taken from our standard vantage point):Ĭanon EF 100mm F2.The EF 100mm f/2.8L Macro IS USM has a true macro magnification ratio of 1:1, meaning the object you are photographing in real life is the same size as on your camera sensor.

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'). 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 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.Ĭanon makes some quite specific claims for the effectiveness of its new IS system, and it's worth looking at these in detail. 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 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. 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. 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. 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. The subject was a novel 'Hybrid' optical image stabilization system designed to compensate for two distinct types of camera shake. Back in July, Canon took the distinctly unusual step of announcing a new technological development completely in isolation from any products.
