Wdc Tests Four Extreme Wideangle Zooms From Independents

It would have been a flight of pure fancy to suggest, just a few years ago, that an ultra-wide zoom could be both affordable and offer sufficient image quality to make the lens worth purchasing (no matter how cheap It may be). Even modest wideangie lenses ran be tricky when it comes to delivering both affordability and quality for traditional SLR users - let alone a zoom that extends close to the equivalent of a tantalising full-frame 14mm extreme wideangte.

Rangefinder cameras have long had the advantage here as their thinner bodies, made possible by the lac< of a mirror-box, don't restrict lens design in the same way. Smaller DSLRi potentially occupy a middle-ground and might be expected partially to ease design restrictions on sho+foca I-length lenses. Fortín is reason it might hp unfair to compare a Four Thirds ultra-wide zoom with a similar lens that is subject to full-frame camera design limitations. The latter category includes, of course, APS-C bodies that maintain lens compatibility with their full-frame stable mates. This review therefore uses only APS-C type cameras to test four ultra-wide zooms from three independent manufacturers: Sigma, Tamron and Tokina. Interestingly, one of the lenses has full-frame coverage and is paired with a dedicated APS-C lens from the same manufacturer (Sigma).
