The performance figures are generally on a very high level - very good between 200-400mm and still good to very good at 500mm. The level of distortions is exceptionally low throughout the range and vignetting is nothing to worry about on an APS-C DSLR. Add the very good build quality on top combined with the very moderate price tag and you've an attractive package here. The only thing that is missing here is an image stabilizer. Handheld photography is often doomed at such extreme focal lengths due to the need for very fast shutter speeds. An extra support such as a monopod or tripod is surely a good idea - otherwise you'll waste much of the quality potential that this lens can give you. ]]> Sun, 07 Mar 2010 21:36:22 +0100
