Sigma Corporation is pleased to announce the launch of the new 17-70mm F2.8-4.5 DC MACRO lens.  It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor.  This lens has a minimum focusing distance of 7.9.. (20cm) throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. The new lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.  This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2..) and diameter 79mm (3.1..). It performs superbly even in relatively low light conditions indoors or at dusk.  The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods. This lens is also equipped with Zoom Lock Switch that eliminates ..Zoom Creep.. during transportation.

Used Sigma 17-70mm f/2.8-4.5 DC Macro AutoFocus Super Wide Angle Zoom Lens for Canon EOS Digital Cameras undefined

I'm coming from a Tamron only background but I needed a lens with 17-70mm range for skateboarding photographs and the f/2.8 was an added gift. This lens has blown me away, it is fast, works well in dark light and when I added the Circular Polarized Filter my blue skies and contrast just popped. Looking forward towards the end of year to purchase the newer 17-70mm Contemporary lens.

Awesome Lens!!

Nice overall lens.  Perfect range for a walkaround lens on my 50D.  Auto focus can be a bit iffy sometimes.  Capable of producing really sharp images, but output can be inconsistent at times. Fairly good for macro work.

worth the money

Overall, a very nice lens. Price, image quality, and build quality all come together for a great "all around" lens for photographers not wanting to spend the dollars  for Canon "L" lenses. Is it perfect? NO. Does it do a good job at a reasonal price? YES. Even without HSM, focus is fast and sure on my Canon XSi, and photos look fine. I researched a lot before buying, and this lens was the winner in it's class.

Good

Great value

Excellent lens for doing Macro shooting.  Have taken to conservatory and shot photos of orchids in bloom.  The depth you get is like looking directly into the center of bloom.  Fantastic color when used with the new Canon Rebel T1I.

I would definately buy this one

It's not bad so far... i've gotten so use to the sharpness and detail of my fixed length lenses that I'm kinda spoiled.  This is my first Sigma lens in years...  focus is slow... and sometimes tempermental... but not bad for the price...smaller and lighter than my Canon 17-85Is.. and more reliable..(17-85 had the dust thing goin on constantly)...  Good color... strong construction.. and I love the zoom lock..  If you have a stable of super sharp lenses... and need a nice zoom lense for those wide angle shots not covered by your primes... this is not bad.. next sigma will be an EX though...

Not too bad... still testing..

AF misses occasionally (particularly on dense foliage), slight back-focus problem, but my camera can compensate for it. Can be quite sharp at times.  Haven't noticed the soft edges others have mentioned wide open.

Bought this lens to replace the kit lens on my Rebel XTI.  The lens works well and is a real upgrade from the Canon kit lens.  For the $ I recommend it.  Though Tamron is just introducing an 18-270mm with vibration control.  It is a bit pricey,,, but would be an even better option over the kit lens.  If 600$ is out of your budget,, get the Sigma 17-70 and you will be happy.

This is a great lens!!

I reviewed this lens previously, and this is my (2nd) updated review. So I decided to try a 3rd one. This could be the best of the three. Focus is more consistent. The focus problem at 50mm is almost resolved (still sometimes misfocused). Manual focus at 50mm would give better result, if in doubt. So, I was in between the Tamron 28-75mm and this Sigma 17-70mm. I like the constant f2.8 and somewhat more consistent IQ of the Tamron, but I also like the 17mm wide angle, better contrast/auto white balance, and build quality of the Sigma. I decided to go with the Sigma. 17mm was the main selling point, considering its IQ is not far behind the Tamron - and in some cases even on par with. So if you can find a good one (Sigma 17-70mm), you'll be happy with it.

I decided to give it another try...

Nice build quality, good range for a general use lens, reasonable price, works on Canon 10D that doesn't support EF-S lenses. Unfortunately, my copy didn't focus accurately at 17mm between approx 12-25 ft. It would often front focus by 1/2 the actual distance, which is a major error. This occurred with the 300d rebel, 10d, and 40d. Very strange since focusing seemed OK with other focal lengths and distances Stopped testing at this point and returned the lens.

Nice quality but confused focusing

I've tested the (1st) lens at various focal lengths and apertures on different subjects, and come down to several findings:
- Soft focus at 17mm/f2.8 and 70mm/f4.5 (wide open). Stop down aperture did help.
- Really soft focus at 50mm (!),at all apertures.
- Focus somehow is inconsistent at wide end (~17-35mm)
So, of course I returned the lens, thinking I might get a lemon.
I ordered the 2nd one (from a different online retailer). This one is better than the 1st one, but not without some issues. I even tested this lens against the famous Tamron 28-75mm f2.8, and the Sigma held up pretty good! But it still has some focus issue at 50mm. If it didn't have this focus issue at 50mm it would have been a keeper. Now I'm not so sure if I want to keep it or not. Two lenses in a row with the same problem, could it be design issue? I really want to like this lens (because of its 17mm) over the Tamron, but the latter seems more consistent in focusing (the Sigma actually produces more contrast and better colors than the Tamron in general). I'm not sure if I will give it another try (i.e. a 3rd one). If you don't mind getting some soft-focus shots at 50mm, it is a nice lens to have.

Could be a good lens, but not quite.

Focus is tack sharp and, in macro, just about starts at the surface of the lens (UV filter).  Lens creep is an issue, especially when pointed down which seems to be common with Sigmas.  Used it for almost a year now, love it, buy it, done.

Fantastic lens

This lens is awesome bright claer and solidly built. The lenses Is a great Adjunct  to my new Canon 40D. Well worth the price at a fraction of the price of the comparable Canon. The zoom is a little tighter than I am used to but that means it won't slip from one focal length to anothe when I don't want it to.
My advice buy this lens.

Sigma 17-70 a great lens

This is an excellent all purpose lens with the added benefit of macro work.  I am currently using a Canon Rebel XT and this lens is perfect for taking to any function but it's amazing on the macro end.  It's a little heavy but worth carrying around.

No regrets with this lens

Has been a great back up lens. Used on back up body for weddig photography and does a wonderful job. There are occasional blurry photo's for no reason, but it's rare.All in all has been a wonderful lens and works well in low light.

Excellent Lens

This is a great and affordable lens.  I've used it in all kinds of lighting situations and have never had problems.  Works well with filters and hoods.

Excellent, affordable lens.

Excellent low-light and macro performance, short minimum focus distance make it excellent for museum exhibit photography or photoos of craft projects. Low geometric distortion for the price. Autofocus is a little slow. Has become my #1 "walkaround" lens for general photography. (I'm a serious amateur but not a pro.)

Great for serious amateur, not for pro

What an unexpected surprise!  This lens is awesome, I had my doubts, but the construction is superb, the resulting pictures are clear and bright.  Great macro too!  Performs well in hand-held, low-light photography and bright daylight shots too.  This is my new everyday lens.
