Practically A Prime: Sigma EX 12-24mm Lens Review
Sigma have recently released a new wide-angle zoom lens which will appeal to all digital SLR owners. The Sigma 12-24/F4.5-5.6 ex DG Asph may be quite slow but it will translate to a 19-38mm lens on a Canon EOS 10D/300D, for example. An extensive review of the new lens with lots of sample photos has been posted by Petteri Sulonen.
“The Sigma EX 12-24/4.5-5.6, hereby christened “Popeye,” because of its bulgy front element, occupies a unique niche among lenses. It’s the first rectilinear 12 mm lens designed for 35 mm SLR’s (yes, it’s full frame). In fact, I believe it’s only the second 12 mm rectilinear lens for the 35 mm format. The first was the Voigtl?nder Heliar ultra-wide 12/5.6—considered remarkable enough to rejuvenate an entire lens mount (Leica M39). This is something to keep in mind for the folks who gripe that Popeye isn’t too bright. In other words, it breaks very significant new ground by the simple fact of existing.”
