I bought it used at 211 pounds and for that price the lens is superb. The quality of the image is great and focus perfect & fast on my Nikon D7500. Much sharper than my old Nikon 16-85mm lens.

[...] 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

Poor picture quality

Sigma's 17-70mm f/2.8-4 DC Macro OS HSM lens is an upgrade to the AF 17-70mm f/2.8-4.5 DC Macro lens released in 2006. Designed for the smaller imaging circle of cameras with APS-C sized sensors, it is slightly larger and heavier than its predecessor and has a more complex optical construction.

You want an affordable general-purpose lens to replace a standard kit lens, You'd like a lens that requires no readjustment when you fit polarisers and graduated filters; Don't buy this lens if, You require a lens with excellent flatness of field and edge-to-edge sharpness, You need true macro...

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.

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...

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 have been using this lens quite a bit now and find it ti be flawless. Very well made and sturdy but a bit heavy but I don't mind. I would recommend this lens to any amateur photograph.

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.

Fits the bill as the perfect walk around lens for my 77D. Image quality is very good with nice color rendition and weighs half as much as the 24-105 f/4L. If you shoot both full frame and crop sensor I say get this lens for your crop sensor camera and leave your 24-105 f/4L on you full frame camera.

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.
