PC Magazine

  • Conclusion: The Sigma 17-50mm F2.8 EX DC OS HSM Lens is a standard zoom for APS-C digital cameras. The lens has a fast f/2.8 aperture through its zoom range, but isn't that sharp when shot wide open.
  • Pros: Fixed f/2.8 aperture. Useful zoom range. Includes hood. Optical image stabilization.
  • Cons: Soft wide open.

19 August 2009
  • Excerpt: Gary Wolstenholme takes a look at Sigma's flagship standard zoom for APS-C digital SLR cameras. Sigma's 17-50mm f/2.8 EX DC OS HSM costs around £590 and is available for Sigma, Canon, Nikon, Sony and Pentax SLR cameras that have an APS-C or smaller sized sensor. The lens features a fast maximum aperture of f/2.8 throughout the range, silent focusing and optical stabilisation.
  • Pros: Excellent performance in the centre between 28 and 50mm when stopped down, Effective Optical Stabiliser, Compact and lightweight for an f/2.8 zoom
  • Cons: Lens really needs stopping down for best results, Sharpness towards the edges,, Focus ring cannot be disengaged

Lens Test: Sigma 17-50mm f/2.8 EX DC OS HSM AF

  • Excerpt: Digital-only speedsters in the 16–55mm range are at home in the Canon, Nikon, Pentax, and Tamron catalogs. All offer fast f/2.8 constant apertures and image stabilization (except for the Pentax, which puts IS in the camera). Now Sigma joins them with this 17–50mm OS ($670, street), its first high-speed, stabilized, wide-angle zoom made for APS-C bodies.

Sigma 17-50mm f/2.8 EX DC OS HSM review

  • Summary: On paper this lens look like a winner. The specification for the price is very good indeed. Although the resolution in the centre is usually good, the same cannot be said about the quality towards the edges, especially at wide apertures.
  • Pros: Excellent performance in the centre between 28 and 50mm when stopped down, Effective Optical Stabiliser, Compact and lightweight for an f/2.8 zoom
  • Cons: Lens really needs stopping down for best results, Sharpness towards the edges,, Focus ring cannot be disengaged

17-50 mm f/2.8 EX DC OS HSM

30 July 2010
  • Excerpt: Originally posted 2010-07-29 on Optyczne.pl When digital cameras with APS-C/DX format sensors appeared on the market, it became obvious that sooner or later the optics manufacturers would have to face a problem of constructing the equivalent of a standard journalistic f/2.8 lens which, in the case of full frame, should have the focal lengths range from 24-28 mm to 70-75 mm.
  • Cons: noticeable chromatic aberration at the shortest focal length,, a bit too high vignetting,, significant coma at 17 mm,, too simplified manual focus ring,, image quality at the maximum aperture, at the edge of the frame for shorter focal lengths could have been better.

  • Conclusion: The distinctive rattle when we first lifted the lens up to the camera body made our hearts sink. Thankfully our initial fears were unfounded, as shooting at all focal lengths during our time at a local market showed impressive image quality throughout the frame, and reinforced the solid results we'd already found when we shot our test chart in the studio. With its near-silent focusing you could easily shoot away discreetly without anyone hearing a thing.

Sigma AF 17-50mm f/2.8 EX DC HSM OS - Review / Test Report

photozone.de
15 October 2009
  • Conclusion: The Sigma AF 17-50mm f/2.8 EX DC HSM OS is a highly competitive APS-C standard zoom lens and Sigma's best product in this class so far. It's not a flawless lens but none really is. Its biggest weakness is the performance at f/2.8 - the resolution in the image center is already exceedingly high here but the image corners are soft between 17-35mm and there's some vignetting at the extreme ends of the zoom range.
