Review: Best Lens I Own...Even more than 24-70mm f2.8 L. - Absolutely my favorite lens of all. As a "semi-pro" and extreme hobbyist I must say that I like the quality of images from this lens on my Canon T3i even more than I like the quality of images from my Canon 5D Mark iii and the 24-70mm f2.8 L series lens; which would be the full frame equivalent to this lens on a APS-C sensor. Yes! I know that at this juncture some of you may be shaking your heads, but it is true. Granted, the 5D does have better image quality and more megapixels, but time and time again I get better images from this lens on my crop sensor cameras. Would you rather get almost the same image quality out of a lens that is 1/4 the expense? I sure as heck would. This lens paired with a T2i, T3i, T4i, or T5i will yield similar or better image quality in most situations than the 24-70mm f2.8 L series lens will on a full frame camera. Which if you are on a budget this is the lens for you! The images are so tack sharp and spot on. I read through many of the 1 star reviews and realized that the majority of the complaints come from Canon users that "got a bad copy" of the lens. As for me, I have a great copy. It is 3rd party glass but better than ANY canon glass I own (Once again some of you are shaking your heads). To me it's worth the gamble, and as long as you got it on desertcart and it doesn't work...send it back for a full refund! In addition to photography, the creamy bokeh that you get from this lens on video is astounding as well. The image stabilization, Optical Stabilization for Sigma (OS), is spot on. The only down side to the OS is that you can hear the gears working as you shift around hand-holding. Not so loud that it would be awkward while shooting an event. The focus ring has minimal resistance which I like; It allows you to get to rack focus faster. The auto focus is spot on and fast. The focus ring also stops at infinity focus as well at it's minimum distance. A feature I like because you know at what distance your subject is and you can switch subjects quickly. For manual focus you should be able to rack focus with a short minimal turn; unlike other lenses that require you to take your hand off the focus ring and do a second turn. Some would say that f2.8 isn't fast enough, but I find it to be plenty fast for most practical applications. You will not regret this purchase!
Review: A Stellar Lens - After purchasing this lens I had to join the chorus of praise heaped on it. I had all the intentions of getting the Canon EF-S 17-55mm f/2.8 IS to go with my new Canon EOS 60D . However the recent January-March price drop of $60 sealed the deal. I figured it was worth the gamble, or as I've often seen it referred to "the Sigma lottery". The reviews on this lens have been in for a long time, and most of them are quite positive. Some even rate this lens better than the venerable Canon EF-S 17-55. However, there is also the black cloud that seems to hang over Sigma's head - that of variable quality control. You'll see the bitter reviews of folks with bad experiences right here. If you hang around the camera forums, this can get to be even more depressing. People going through all kinds of tests for their lenses, constantly trading them back in for better copies. Or, claiming after going through 2 or three or five copies finally giving up. The brand that usually seems to pop up most often is Sigma. Perhaps because they (more than others) have a range of lenses that go toe-to-toe with the big boys. In some cases they're just as pricey as Canon or Nikkor. The 17-50 is claimed by some to be as sharp, and even sharper than the 17-55 at above f4. For almost half the price I figured it was worth a shot, and this seems to be one of those rare cases where I really feel I got my monies worth. There are some trade-offs in features, but not quality. One thing I'll mention right away that I've seen mentioned elsewhere, and that's a "rattling" noise the OS makes when you shake the lens. Now, it never occurred to me to shake my lens. But I guess I'm odd that way! So, now than I finally have the thing I shook it. You know what? I don't hear it. I mean, I can hear a bit of movement, but nothing like my EF-S 17-85 for instance. Take that for what it's worth! I decided to first test the lens on my "I know how it works and I know it's working" XTi Rebel. The first shots looked promising, and further tests showed it to be sharper than many reviews I've seen. I've posted a photo of the lens center and extreme corner at 17mm f2.8, where the lens is purported to be at its worst. It only gets better from there! After pairing to my 60D, well, keep reading! Fit and finish: This new Sigma no longer uses their matt crinkle sort of rubberized finish. While I liked the old finish, it showed marks, collected dirt and is very hard to clean. The new matt finish is smooth and nice, perhaps nicer than the speckled finish of the Canon EF-S series. The lens feels as of-a-piece, there's not a hollow spot or loose fitting anything anywhere. One complaint I see popping up regards the lens hood fit. At first I was all there with the "it barely hangs on" thing. Jeez, what's up with that? Oh. Duh. You rotate it a bit harder and it snaps in place. A firm "click". Nice. It's not going anywhere. This is very different from past Sigmas and the Canon EF-S lens hoods, which while nicely finished are still flimsy and don't fit all that great. The interior is not ribbed like old Sigmas, nor flocked like Canons, just a simple matte finish. At least it didn't cost $35! Other than that you'll find a zoom lock, AF/Manual and OS On/Off switches. One bizarre characteristic can be seen when viewing the mount and back element. If you zoom the lens out and the element travels inward, the camera's electronics are exposed! I found this weird enough to check my other lenses, and no, this is unique. I guess just don't check it out in a rainstorm and you're good to go. My final comment is that there is no distance scale window (just a distance scale on the barrel), an obvious price cutting issue. I don't really use the scale for a lens this size, but miss the little jewel like window all the same. Function: It is extremely solid and operates smoothly. The zoom is nice and smooth with a good amount of equal resistance in both directions. There is zero creep, and even still there's a zoom lock. This can't be said for the EF-S 17-55. The biggest issue I've got as others have mentioned is the overly thin rotating focus ring and short focus rotation of about 45 degrees (!) with hard stop. This is not a big issue for me in still photography, but it seems this could be a problem with video and somebody as ham-fisted as I am. The feel of the focus ring while smooth offers almost no resistance. In comparison, my other lenses are far superior in feel. Again if manual focus is a priority then this should be a consideration. The switches are a huge improvement over some past Sigmas, and each snaps quickly and firmly with identical feels. The zoom lock is quite small and there's no chance of accidentally hitting it, but it's large enough and has a positive enough feel to find and engage with confidence. Performance: The AF is fast, as fast as any lens I've got. Perhaps it's so fast because of the short focus ring distance? It's not at all noisy. No hunting, no hesitation. Even in low contrast conditions it's just bang on. Considering the horror stories I've heard about the AF, this is another one for the mystery files. OS is another thing - while I've got a pretty steady hand (at certain times of the day, depending on barometric pressure and planet alignment) I'll assume it's doing its job. All the low-light shots with slow shutter speeds I've taken look great - consistent down to 1/10. 1/6 not so much. They claim 4 stops worth so I'll assume it's 3 and call it good! The OS is not at all noisy either, it was enough to concern me at first! I had to put my ear up to it and depress the shutter to confirm its operation when I first started. Summary, AF and OS are everything they should be and more. IQ: It's incredibly sharp across the board. At 17mm and f2.8 is tack sharp center, with a slight softening in the corners - and I do mean slight. at 28mm and above it's mind-boggling. Seriously, I simply can't believe how sharp this thing is wide open. I'd have to say if there's a sweet spot it's around 5.6, but it really is wonderful up to about f/11. Typically, pixel peeping at 100% can be a depressing thing on a Canon APS-C camera. Now I just giggle! Vignetting is quite apparent at the shortest focal length as would be expected, but very evenly gradated. CA is evident in extreme corners at all ranges, most notably distant high contrast objects. On my copy it only seems to be red fringing towards the outside, highly controllable in PP. Barrel distortion is pronounced at 17mm both vertically and horizontally. In comparison, my Sigma 10-20 f4-5.6 has almost no vertical distortion at 10mm. Distortion is pretty much gone by around 24 up. Really nothing unusual for this type of lens. I've actually found my distortion problems go away after owning a lens for a few weeks anyway! Why? I tend to stop shooting brick walls and start shooting other things instead. Of course, the vignetting and distortion are easily fixed as is CA using Lightroom, Photoshop, DxO or a host of other applications. Contrast is another place this lens really shines, as what I would expect from an L series lens. Colors are deep and rich if slightly on the warm side. Flare seems well controlled, I've shot pretty much into the sun with no issues. Bokeh? Meh. It's good, pleasing actually, but nothing I'd call creamy or recommend the lens for. Bright objects do tend to have outlines, but no real fringing, odd shapes, holes or halos. You'll be able to find lots of samples both here and in reviews at lenstip dot com or photozone dot de. Pros - Great fit and finish - Excellent size and weight - Fast, accurate AF - F2.8 is better than usable! - Sharp, great contrast - Better than advertized corner sharpness - Low CA - Image Stabilization - 60% the price of the EF-S 17-55 - Comes with case - Comes with lens hood - Center pinch and edge pinch lens cap like most "modern" lens manufacturers (hello Canon?) - Great warranty Cons - Skinny focus ring - Rotating focus ring - Manual focus turn only 45° - Focus ring hard stop - Mediocre focus ring feel and resistance - No full time manual focus - Vignetting at lower focal lengths - No distance scale window - Short focal length - Possible QC issues - Always run the risk of future EOS body incompatibility with third party lenses If you need an f2.8 type lens, I highly recommend giving Sigma a look. If you're looking to replace your kit lens, or are really only going to have 1 lens you may consider something with more of a focal length like the EF-S 15-85 f3.5-5.6. Basically in this category of lenses there are only about 4 choices. The Canon EF-S 17-55, the Tamron AF 17-50mm F/2.8 XR Di-II LD SP , the Tamron AF 17-50mm F/2.8 SP XR Di II VC and this. IMHO, the Tamron lenses are out of the running for either being sharp with no VC, or not sharp with VC. Tamron build quality is good but not great IMO. The Canon is top notch IQ but not top notch build, and then (are you listening Canon?) you still have to pony up for a mandatory and potentially lens-saving hood. All I can say is this is a perfect "specialized" walk-around for crop bodies as others have mentioned. For indoor shooting it's a winner. You've got f2.8 in a small well built package that's razor sharp at f4 and above. See my chart test for opinions on f2.8. When introduced this was a pricey lens and it was hard to not consider just spending the extra $200 for an EF-S 17-55. But slowly the price has come down. At its current street price of around $650, it's a deal. Buy it, test it and if you do get a defective copy, then you've been fortunate enough to buy it from desertcart, right? Send it back and get another one, it's just that easy. And speaking of easy, this one is an easy 5 stars.

### ⭐⭐⭐⭐⭐ Great Value, Great optic. Great lens for low light and everyday portrait
*by T***M on August 13, 2020*

I used this lens for Fuji X-T3 camera using Fringer Pro EF-FX adapter. I want a low light 2.8 zoom lens with optical stabilization. Fuji 16-55mm did not have any stabilization so I decided to give this a try. optically, this lens is not better than Fuji 16-55mm. It's not a noticeable difference in the center. It is, however, noticeable in the corners at 2.8- but not significant. If you're not pixel peeping then you will be fine. one thing that i think this Sigma excels over Fuji 16-55mm lens is the color rendition. I just prefer this Sigma colors than Fuji lens..and on a Fuji X-T3, this lens really shines. the size of this lens and the adapter combine is not much bigger than the Fuji 16-55mm lens itself. This lens, however, has image stabilization which is very helpful in video. This definitely make handheld possible when shooting video. the focusing is loud in video, but bearable. You can always use an external mike or use manual focus to get rid of noise. The manual focus on this lens, however, can be difficult as the range of manual focus is quite small- slight turn will shift out of focus right away.. with all these + and - s in mind, i think this lens is great for what it is- low light performance, sharpness, and versatility... 17-50mm range is very useful as a walk around lens for sure. I would pick this over Fuji 16-55mm for the value/performance ratio and over Fuji 18-55mm for its constant 2.8 aperture... I definitely do think optically, this lens is much better than Fuji 18-55mm in every way.
