Product Description

Amazon.com

Designed for Canon digital SLR cameras, the Sigma 17-70mm f/2.8-4.5 macro lens performs superbly even in relatively low light conditions, such as indoors or at dusk. The lens incorporates an inner focusing system that provides a fast autofocus speed while also preventing the front of the lens from rotating. This makes it particularly suitable for use with circular polarizing filters and petal-shaped lens hoods. The lens is also equipped with a zoom lock switch that eliminates "zoom creep" during transportation. And thanks to the special low dispersion (SLD) element and two aspherical elements, the lens corrects for all types of aberrations and produces a high level of optical performance throughout the entire zoom range. Other features include a minimum focusing distance of 7.9 inches, a maximum magnification ratio of 1:2.3, and a multilayer lens coating that reduces flare and ghosting. All Sigma lenses carry a one-year warranty.

This is the first non-Canon lens I've purchased and the Sigma 17-70/2.8-4.5 DC surprised the hell me with its fine performance. Zoom range, speed, resolution, low Chromatic Abberation, fast/sure autofocus speed and solid build quality make this lens stand head and shoulders above the typical cheap Canon kit lens such as the terrible Canon EF 18-55/4.5-5.6. Plus the Sigma has 1:2.3 macro capabilities with very sharp results...AMAZING! I've read more and more reviews all over the Internet on this Sigma lens that praise its qualities. This lens will compete with Canon lenses costing two and 3 times as much (EF 17-40, EF 18-50/2.8, EF 16-35/2.8). The Sigma 17-70 is constructed with one SLD low-dispersion glass element which is responsible for its excellent lack of Chromatic Aberation. At this price I never expected that kind of quality. Highly recommended!

Obviously I was luckier than the previous reviewer: my first copy was, and is, fine.

I use my Sigma with a Canon 400D (XTi in the US). I also have a Canon 50mm lens that's supposed to be really sharp. Maybe I have a bad copy of that, because the Sigma is definitely sharper. In fact I was disappointed with the camera until I bought this Sigma lens.

Now I get images that are sharp and colourful, yet with that smooth SLR look that was evading me when using the Canon lens. I'm very pleased with it.

One thing that surprised me was how big and heavy it is though. People look at me as though I have a long zoom (it extends quite a way at 70mm), even though it's really not.

But, you get used to it pretty soon.

I guess it had to be big to get the f/2.8. Trouble is, at about 20mm you lose the f/2.8, so it's not quite as good as it sounds. This lens loses out on that score to the constant f/2.8 17-50 lenses from Tamron and Sigma.

The compensation is that you get a bit of extra reach, which makes it more of an everyday lens.

And the trump card is that you can get really close with this lens. Minimum focus distance is 20cm. Doesn't sound that great, but that's 20cm from the sensor, not the end of the lens. Zoom all the way to 70mm and you can focus on stuff that's almost touching the glass!

I like the feel of the lens. It's very solid and attractively finished, feels expensive.

You get a lens hood in the box, unlike when you buy a Canon lens.

The only thing I don't like is that the focus ring moves in auto focus and I find it often catches on my hand. No big deal.

All in all, a great lens.

I own an XT and 3 lenses: this one, the ef 70-200 f/4 and the 50mm f/1.8. I use them all about equally. This one is versatile in terms of focal length (solidly wide angle to short tele) and it has a pseudo-macro close focus ability that is great for closeups (flowers, large bugs, frogs etc...). While it is not particularly sharp wide open, it is definitely acceptable to me and essentially matches my other two lenses when stopped down. I can't speak to the possibility of "bad copies" that may be "floating around"... mine is satisfactory. There are clearly trade-offs that come with buying a cheaper lens that does several things, but I found this lens to be quite balanced in that respect. Overall I find this lens of good quality and its versatility to be indispensable... until I save up enough to get the ef 100 2.8 macro and the 17-55 2.8IS.

If you are considering buying this as your first lens instead of getting the kit, I unreservedly recommend doing that (especially if it will be your only lens for a while). I owned the kit with my first XT (lost to a break-in) and frequently chafed at its limitations (slowness, minimum focus distance, short focal length) and I think you would find that the modest improvements in these attributes that come with this lens will greatly increase your enjoyment of your camera.

Verified Purchase
This is an amazingly versatile lense, and I'm delighted with it. I've had it for about a month and have shot more than 1000 photos with it. I take close ups of flowers and I can get so close with the macro I'm afraid I'm going to touch the object with the lens. The wide angle is all I need for my Canon digital camera, and the telephoto is great for portraits and a lot of my landscape shooting. Autofocus is fast and quiet, and the lens is build solidly. If I could have only one lens, this one would be it.

I've had this lens for a few weeks now, and have been experimenting with it since I've gotten it. I absolutely love the macro feature, as I've been taking all sorts of wonderful closeup shots of my wife's flowers, and have been very pleased with the results. I've also been doing a variety of landscape photos out at a local beach, and again, the results have exceeded my expectations, especially given this lens' price! I bought this to replace the pretty useless 18-55mm kit lens my Rebel XT came with, and I haven't regretted this in the slightest. I looked up an awful lot of reviews, and most regarding this lens were very positive (which was good ... but I also did find that for everyone who loves a particular lens, there's someone out there who hates it, so take every review with a grain of salt), but the clincher was the price. I do not have the kind of money necessary to buy Canon L lenses, and I doubt I ever will (food, mortgage, home repairs, etc. are a bit higher on my list), so this lens was a compromise, one that I've found to be very satisfactory. I may be just a weekend photographer, but I still want good quality for my limited budget, and this fits the bill.
