Sigma 150–500mm f/5–6.3 APO DG OS HSM
16 December 2014
Excerpt: Sigma continues to innovate with their 150–500mm f/5–6.3 APO DG OS HSM ultra-telephoto lens. While designed for full-frame sensors, it’s equally at home when used with smaller APS-C sensors. That’s a lot of flexibility for one lens. This is a lens that’s not only affordable, but ideal for subject matter as diverse as nature, wildlife, sports, and portraiture where compression trumps wider apertures.
Excerpt: The Sigma 150-500mm f/5-6.3 DG OS HSM is a stabilized super-telephoto zoom lens; indeed it's one of only two stabilized telephoto zoom lenses reaching 500mm focal length, the other being Sigma's own 50-500mm 4.5-6.3 DG OS HSM.
Excerpt: Sigmaniacs and assorted bloggers have, over the years, dubbed Sigma's longer tele zooms with nicknames that seem to have stuck. The 50-500mm f/4-6.3, for example, is known as "the Bigma." The 300-800mm f/5.6 is the Sigmazilla. It prompts the question: what should we call this new OS-enabled 150-500mm f/5-6.3?
Sigma APO 150-500mm f/5-6.3 DG OS HSM Lens; A Long Range Zoom with Image Stabilization
28 April 2010
Excerpt: 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...
Excerpt: The focal range of this optic will generally appeal to budding wildlife photographers after that extra bit of reach, without the expense of manufacturers own offerings, or the inconvenience of prime lenses. Photographers looking at this lens may also be tempted by Sigma's 120-400mm offering, which costs around £100 less, but is 100mm shorter at the long end.
Excerpt: The Sigma 150-500mm f/5-6.3 DG OS HSM is the company's latest offering in the extreme telephoto zoom budget marketplace and it kicks in with a few eyebrow raising surprises! Replacing the 170-500mm model that is now quite long in the tooth the new lens has a good specification for its price.
Pros: Fast focusing, Good stabilisation system, Excellent value for money, Relatively compact
Cons: OS system slightly noisy, Tripod foot could be half inch longer to make more comfortable handle.
Summary: Overall, the Sigma 150-500mm f5-6.3 DG OS HSM superzoom works best in AF mode and its Optical Stabiliser is best reserved for improving viewing rather than the quality of captured images. The heavy-duty padded case is a useful addition but it is a shame that some aspects of handling are rather awkward.
Pros: Impressively quick and quiet automatic-focusing
