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.

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.

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.

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.

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

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.

This lens exceeds my expectations (based on reviews that I read online) on all aspect, it is both fast and sharp. the provided lens hood is also a bonus. quite heavy though but that should be fine because you'll be getting higher quality photos compared to any standard kit lenses (I was using...

The Sigma 17-70mm F2.8 -4 DC Macro OS HSM is the practical zoom. A large-aperture, standard zoom lens for digital cameras with an open-aperture value of F2.8 (at 17mm) and covers the most frequently used focal lengths.

The 17-70mm focal range is also close to what's possible before a swag of optical performance compromises come into play in order to enable a longer zooming ratio. Consequently, the Sigma is a strong performer across its entire focal range with excellent uniformity of sharpness and brightness.

[...] I HAVE TRIED THIS LENS ON MY NIKON D300S AND WAS DISAPPOINTED WITH THE PICTURE QUALITY NOT TO MENTION THE COST OF THIS LENS.

Durable; Well Made
