zooms

For quite some time, F/2.8 has been the pinnacle when it comes to zoom lens aperture, but Sigma has raised the stakes a bit, at least for APS-C sensor DSLRs. Their new 18-35mm DC HSM zoom lens maintains a maximum aperture of F/1.8. That's a pretty big deal.The new lens has a full-frame equivalent field of view of 27-52.5mm, making it a little shorter than the typical 24-70mm standard zoom. it focuses to a minimum distance of 11-inches and has a maximum magnification ratio of 1:4.3, which isn't exceptionally close for a lens like this. 

Last week you saw some new gear sneak out from Sony Europe, including the new NEX-3N and the a58. Well, now that everything is official here in the States, they have some new lenses as well.

Three lenses that were announced at Photokina have been made available in the USA, giving us a firm pricetag for this trio of third party glass.

The 70-200mm zoom has been an essential lens for some time now, and Nikon has a new version that's a little slower, but cheaper, smaller, lighter, and sports five stops of Vibration Reduction.It weighs in at 30-ounces on the nose and measures 7-inches long. Small for a 70-200mm lens. It will also focus down to 3.28-feet, which is fairly close for a lens this long.
