Sigma are releasing 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. Digicamera.net have spotted a short review of a production lens on the Nikonians website. Here’s an extract:

“It looked pretty balanced on the D100, not bad at all. Interestingly enough, it has a double lens cap scenerio. There is a lens cap that comes on and off just like any other cap, but there is also a removable hood. You can put the lens cap on and then pull off the hood and there is a permanent petal hood. My guess here, is that the simple cap can be used with a DSLR, but with a full SLR you need to pull the entire thing off to avoid vignetting.”
