In the trifecta of portrait lenses—85mm, 105mm, and 135mm—the 85mm focal length is the gateway. It’s short enough for tight shooting spaces, while producing a real portrait look, yet versatile enough for use in other genres, including photojournalism, where a nifty 50 comes up a bit short. Enter Sigma’s 85mm f/1.4 DG HSM Art lens ($1,199) that’s fast enough for reportage and long enough for portraiture.

The Sigma APO 150-50mm lens is a moderately fast, super-telephoto zoom designed to work with both APS-C and full-frame DSLR cameras. It offers quite useful close focusing (7.2 ft) and two modes of what they deem "optical stabilization" (OS.) Weighing in at 67.4 oz you always know its there, but then again this is one impressive piece of...

Although Sigma released their first lens with a built-in Optical Stabilizer (OS) system in the spring of 2004, the company employed this technology in only one pro-grade lens, the 80-400mm f/4.5-5.6. That has changed with the introduction of a more compact/affordable (digital-only) 18-200mm OS zoom. Sigma will not comment about future plans, but a reliable source indicates that...

That makes sense because the same focal length with a wide aperture would be larger, heavier, and more expensive due to the oversized optical elements and barrel. Even so, many photo enthusiasts really appreciate an...

While searching for a new portrait lens I saw Sigma's APO MACRO 150mm f/2.8 on their website. But wait, you say, this is a macro lens, not a portrait lens! Here's my thinking: Any portrait photographer out there worth his light meter will gladly extol the virtues of a long, fast lens for portraiture. The reasons are simple--limited angle of view to get rid of...

If, like many Shutterbug readers, you have a film SLR camera plus several interchangeable lenses, you might be wondering if you can use those lenses with your new D-SLR camera of the same, or even different, brand.
