The Sigma 70-300mm f/4-5.6 DG OS telephoto zoom lens is the second lens from Sigma that I’ve tested out, and have to say it is a nice piece of glass. The lens, which incorporates an Optical Stabilizer, is compatible with Nikon, Canon, Sony/Minolta, and Pentax mount bodies.
Minimum focusing distance is 59.1-inches, and the lens uses a 62mm filter. The lens offers a 34.3 degree angle of view at the wide 70mm end and 8.2 degrees of view zoomed in at 300mm. Aperture range is f/4-5.6 through f/22. For a lens with such a wide zoom range, it’s not extremely heavy, weighing in at only 610 grams. The lens has a nine blade diaphragm, and although it isn’t an f/2.8 lens, it does offer a nice out of focus blur at f/4.
Designed for use with DSLRs that incorporate full frame image sensors, the lens can also be used with camera bodies that use the smaller APS-C sized sensors. When used on a camera with an APS-C sensor, the lens effectively becomes a 100-450mm lens.
According to Sigma, for the Sony and Pentax mount lenses, you can use the optical stabilizer even if the camera body has a built-in anti-shake function.
The 70-300mm f/4-5.6 DG OS lens uses Special Low Dispersion glass elements. The Super Multi-Layer Coating reduces flare and ghosting, providing high contrast throughout the entire focal range.
I’ve been using the lens on a Canon EOS 5D Mark II body, and found it to be quick to focus, producing sharp images. Canon’s 5D Mark II has a full frame image sensor, so the lens was accurate at the 70-300mm zoom range. The images from this lens were as sharp as I’ve seen with Canon brand lenses.
As I mentioned in the review of the Sigma 10-20mm wide-angle zoom, posted on Picture-soup.com last summer, there are folks who don’t think third-party lenses are as good as those made by the camera maker. From my experience using Sigma lenses I think they’re definitely worth the money. The money you save by buying a Sigma lens doesn’t come with degradation in quality.
MSRP of the lens is $599.00. For more information, check out the website at www.sigmaphoto.com.
