Optical Image Stabilization. The EF 100mm F2.8 L IS USM's party trick is its new Hybrid Image Stabilization, which Canon claims to be the first system that is genuinely effective at macro distances. Despite this the company only claims a benefit of 2 stops at 1:1 macro, as opposed to 4 stops at more 'normal' distances.
