Just posted! Our lens review of the Canon EF 100mm F2.8 L IS USM. A few months ago Canon announced a new optical image stabilisation technology, dubbed 'Hybrid IS', that promises greater effectiveness at close distances for which conventional IS systems tend to be ineffective. The first lens to feature this has duly arrived in the shape of Canon's latest 100mm Macro, which alongside image stabilisation has also gained the added attraction of the premium 'L' designation. We take a close look to see if it's worth the premium over the older EF 100mm F2.8 USM Macro, which remains in Canon's range.
