Sigma AF 17-70mm f/2.8-4 DC HSM OS | C (Nikon) - Review / Test Report
28 July 2013
Conclusion: The Sigma AF 17-70mm f/2.8-4 DC HSM OS | C delivers very solid performance, with very good to excellent resolution in the image center and very good border and corner resolution and most focal length and aperture settings. The only exception are somewhat soft borders and corners at the shortest focal length with large aperture settings. The build quality is on a high level for a consumer zoom. Thanks to HSM, the AF is reasonably fast and nearly silent.
Excerpt: This 4.1x zoom lens for APS-C format cameras sports a variable f/2.8-4 maximum aperture, silent focusing, optical stabilisation and a closest focusing distance of 22cm throughout the zoom range. The zoom range is roughly equivalent to that of a 25.5-105mm lens used on a 35mm camera. It is available to fit Canon, Nikon and Sigma cameras and costs around £350.
Pros: Very good sharpness in the centre, Good build quality, Close focusing, Optical stabilisation
Cons: Drop off in clarity towards edges as lens is zoomed in may concern some people, Barrel distortion at 17mm
Sigma AF 17-70mm f/2.8-4 DC HSM OS macro - Lab Test / Review
4 December 2011
Conclusion: The Sigma AF 17-70mm f/2.8-4 DC HSM OS remains a fairly obvious candidate for budget oriented consumers. It may not reach stellar performance levels but the resolution figures are generally very decent. However, you may try to avoid the f/2.8 setting at 17mm due to fairly soft corners and high vignetting. Like most standard zoom lenses it shows a pronounced degree of barrel distortion at 17mm whereas other focal lengths are less affected.

4 August 2011
Conclusion: The Sigma AF 17-70mm f/2.8-4 DC HSM OS is a fairly obvious candidate for budget oriented consumers. It may not reach stellar performance levels but the resolution figures are generally very decent. However, for best results you may want to avoid the largest aperture settings due to somewhat soft borders and high vignetting.
Summary: The Sigma 17-70 mm 2.8-4.0 DC Macro OS HSM has a much more interesting zoom range than the Canon 18-55 mm kit lens. Those extra millimeters on the telephoto side allows this lens to work as a portrait lens. The resolution is, except for the wide angle, higher than the resolution of the Canon 17-85 mm 4-5.6 and the Canon 15-85 3.5-5.6 mm.
Pros: Very good resolution in the center at all focal lengths for a lens in this class, Good to very good resolution in the corners, except for 17 mm, Practical zoom range, Very fast autofocus, Solid touch, Good price to quality ratio
Cons: Very poor sharpness at 17 mm in the corners, High distortion at 17 mm, Sensitive to backlight, Chromatic aberration at 17 mm on the high side
