The EF 100mm f/2.8L Macro IS USM has an array of switches down the side of the lens allowing for several control options. The focus distance limiter now offers three options – full, long-range limited (0.5m to infinity), & macro (0.3m to 0.5m). In late 2009 Canon introduced a ‘Hybrid Image Stabilizer’ that corrects for both linear & rotational shake making this lens a great option to portrait style shooting or macro work.
