No promises, but I would like to complete a full Sigma 17-70mm f/2.8-4 DC Macro OS C Lens review in the future. For now, please review the standard test results available for this lens and view the eye candy below.

I've had the lens now for 1 week and I've put it thru some basic macro and non-macro shots in both low-light, ambient light and sunlight conditions. The lens has performed exceptional in all instances. Paired with my new Canon T4i camera I am getting amazing images in my opinion.

Outstanding macro; sharp images; excellent OS

zoom rotation is backwards from the other Sigma lenses I've used

Very versatile range, and macro. Fast, and very sharp, especially on a tripod. I like the zoom lock and the feel of this lens is solid.

Tried to save some money by buying an after market product. Did not take go pictures when lens was entended out to 70mm. Built cheap. You get what you pay for. Taking back. Going to get the actual Canon lens.

The kit lenses you get with digital SLRs are good value, but they're not always terribly good lenses. The problem is though, that the next step up from the camera maker's own lens range is a big one. For example, Canon's EF-S 17-85mm has a list price of £600 and Nikon' 16-85mm is £550.

Flipkart, as usual, delivered it before the delivery date. So I am a happy customer. I am now using the lens for many days now. It feels sturdy. It is sharp throughout the focal length and aperture wide open. It doesn't lose contrast even on heavily backlit scene.

I tested the lens taking many pictures with my D7000 and D600. The pictures were not as good as I expected

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is designed as an upgrade to the 18-55mm kit lenses supplied with most SLRs, and offers an interesting middle ground between fast zooms of the 17-50mm F2.8 type, and extended-range zooms in the 16-85mm class.

Useful combination of zoom range and relatively fast aperture; Very good image quality across most of the range; Compact size; Reasonably fast and near-silent autofocus; Effective image stabilisation

Somewhat weak image quality at wideangle (soft corners and chromatic aberration; Macro shooting a little impractical (very short working distance

Sigma's latest 'C' badged 17-70mm F2.8-4 is an excellent upgrade option for SLR shooters who've outgrown their kit zooms, and are looking for better image quality and more creative flexibility. It offers a fine balance of zoom range and maximum aperture, while still being highly portable. Autofocus and image stabilisation both work well, but image quality at wideangle isn't the best.

Photographers looking for a high quality, general purpose zoom for everyday shooting.;

Wideangle or close-up shots;
