The EF-S 18-200mm F3.5-5.6 IS is Canon's latest zoom lens for APS-C format DSLRs, introduced as a companion to the EOS 50D. Its announcement in August this year came as no great surprise, as wide focal length range 'superzooms' are clearly popular amongst photographers seeking an all-in-one lens for travel and everyday shooting. The most obvious example of this is the runaway success of Nikon's AF-S 18-200mm F3.5-5.6G VR, and a Canon equivalent has almost certainly been the most-requested lens on our forums.
With its 11x zoom range, the 18-200mm becomes Canon's most ambitious consumer-level zoom to date; the company has previously shied away from producing relatively inexpensive superzooms, with its only previous foray into this sector being the 28-200mm F3.5-5.6 (USM) for 35mm SLRs from late 2000. And while it's this older lens that the 18-200mm most strongly resembles, Canon has managed to squeeze plenty more into the design in the intervening eight years. The zoom ratio has been stretched to a 35mm-equivalent range of 29-320mm, and the new lens incorporates Canon's latest compact image stabilization unit (as seen on the EF-S 18-55mm F3.5-5.6 IS and the EF-S 55-250mm F4.5-5.6 IS), which offers automatic panning detection and (according to the company) four stops of stabilization. All this has been achieved using a suitably complex optical design of 16 elements in 12 groups, including two UD glass elements and two aspherical elements which are designed to minimize chromatic aberration and ensure crisp corner-to-corner detail across the zoom range. Rounding off the specification is a minimum focus distance of 45cm/1.5ft at all focal lengths.
One design decision may however cause a degree of dismay; the lens uses a relatively unsophisticated micro motor system for autofocus, as opposed to the ring-type USM design more commonly seen on mid-range lenses such as the EF-S 17-85mm F4-5.6 IS USM. Consequently, potential buyers may struggle to find any obvious advantage over Tamron's recently announced 18-270mm F3.5-6.3Di II VC LD Aspherical (IF) Macro, which sports a longer zoom range and Tamron's own optical stabilization system. Aside from this, Canon have produced a lens which is clearly designed to counter the undeniable buyer appeal of Nikon's popular 18-200mm VR head-on; so how does it match up to the challenge?
