Canon EF 28-300mm 1:3.5-5.6 L IS USM

The Canon EF 28-300mm f/3.5-5.6 USM L IS is an impressive extreme range zoom. The optical quality is on a very high though not exceptional level. The resolution figures are generally very good without any major flaws. Vignetting, CAs and even distortions are very well under control. The build quality is exceptional though some may not like the push-pull zoom design. With a little positive attitude you should be able to get used to it though and the very smooth zoom action helps a lot in the transition phase (from conventional zooms). The 3rd generation IS is a significant and highly welcome addition to the feature list. On the downside the lens is heavy and not exactly small especially when used at 300mm - not exactly a low profile lens. The price lifts it beyond the reach of most amateurs but then this is true for many L grade lenses out there. Unfortunately the lens is no longer a one-size-fits-all solution on APS-C DSLRs but nonetheless it remains an interesting lens for lots of applications. So if you can live with its limitations and the price tag it is surely worth a deeper look!
