This review is from: Tamron AF 17-50mm F/2.8 XR Di-II LD SP Aspherical (IF) Zoom Lens for Canon Digital SLR Cameras (Camera)
This is the kind of lens that makes me wish Canon would understand their market better. Instead of putting out a 17-55mm zoom that everyone can afford, they put out a EF-S non pro lens at a pro price, which has serious quality control issues. Tamron, however, responded.
This lens is quite sharp. It could definately be used for professional purposes. Sharp at 2.8 and much sharper above. After using this lens, the 17-40mm L, as well as the new EF-S 17-55mm, I can honestly say that Tamron beat out Canon in their own game in terms of quality for the money. Great optics, great range, affordable, and a SIX YEAR warranty, as opposed to Canon's weak 1 year warranty. Buy me.

This review is from: Tamron AF 17-50mm F/2.8 XR Di-II LD SP Aspherical (IF) Zoom Lens for Canon Digital SLR Cameras (Camera)
I tested canon 28-105 3.5-4.5, sigma 24-70 2.8, canon 50mm 1.8, canon 18-55 3.5-5.6. I would say this Tamron 17-50 2.8 is my dream lens. I bought canon 28-105 3.5-4.5 for the focal range but was very sad about its softness and returned it. Then I went to sigma. That's a huge, heavy lens and very solid. Based on reviews, it should be very sharp. however, it was not true in my case. No matter how hard I tried, I never got sharp image. I guess I was not lucky enough to have a good copy and returned it in one week. Finally I bought Tamron 17-50mm 2.8. It surprised me from the very first picture. The sharpness is as good as canon 50mm 1.8 prime, the benchmark. Contrast is very good and color too. 7 blade aperture makes very nice blur background. I care so much about sharpness so the lens is my taste. The focusing is very accurate and fast enough, even though not as fast as sigma. Now I never touch canon 18-55 kit lens, the difference is huge. It's true this lens has no IS. But for 17-50mm range, IS is not as useful as for tele lens. The price is excellent considering the top optical quanlity. Now I am feeling I am a pro. :)))
The reasons I choose this lens are: 1. widest angle in the class(most important thing for 1.6X cropping factor sensor camera 2. Very sharp and top quanlity glass 3. light weighted and small and easy to carry 4. 7-blade aperture makes nice background(if you own canon 50mm 1.8 II, you will see its 5-blade aperture makes harsh background) 5. big constant 2.8 aperture through the whole range 6. excellent price

This review is from: Tamron SP AF17-50mm F/2.8 Di II LD Aspherical (IF) Lens with hood for Nikon-D DSLR Cameras (Electronics)
I felt like I was taking a gamble when I bought this lens, because I was not able to find many reviews of it. Given that the equivalent Nikon was almost 3x the price, I decided to take a chance. At this point I still can't give a solid thumbs up or down, so I opted to give it a 3. Here is a short history of my experience:
1) Bought lens from Amazon to use on my D50. It was a joy to have an f/2.8 zoom lens, but I was not totally convinced about the sharpness (which the few reviews I could find said was supposed to be really good). After comparing it to my other lenses and a rented Nikon 17-55 f/2.8 (great lens, but much bulkier and heavier), I determined that it front-focused so much that the subject would always be very slightly out of focus. It wasn't obvious right away, because the front-focusing meant that the background went out of focus really quickly, making for a great depth-of-field effect. The heavily out of focus background essentially made the subject look more focused, even though it really wasn't all that sharp. After much deliberation, I sent it back to Amazon to try another copy. 2) 2nd copy. This one was much sharper but back-focused, which I found to be even more annoying. This would manifest itself by someone's eyes and nose being out of focus and their ears and hairline being razor sharp. After trying to force myself to live with it, I decided I couldn't and sent it off to Tamron for calibration. Several people in lens forums mentioned that this did the trick, so I decided to give that a shot rather than send it back to Amazon (they were out of stock at the time anyway, so it made the decision easier). 3) Tamron told me that they were running slow, so it would take 5 weeks to calibrate it. Again weighing the extra $800 I'd have to pay to buy the Nikon, I decided to send it in. It actually took 8 weeks! And when I wrote them to inquire at the 7 week mark, they said they had no record of it. I think that was just because they had already shipped it, but it did scare me at first. 4) Calibrated lens. My first impression was wow, this thing really is sharp, and I was really glad that I has sent it back in. And that's when I started noticing something strange... many of my shots were looking massively overexposed. I was out on a nice, evenly-lit overcast day, so I wasn't able to figure out why the camera was having such a difficult time metering. After a few more shots, I realized that anything taken at an aperture smaller than f/2.8 would be overexposed, which led me to suspect a problem with the aperture blades. Sure enough, they were stuck wide open, so every picture was at f/2.8, regardless of the actual setting. At this point in the story, I was very unhappy. 5) Tamron customer service. I expressed my frustrations to them in an email over Christmas weekend, and I am happy to say that they responded positively the next business day. They gave me their Fedex #, so that I didn't have to pay return shipping. They also promised that they would keep it for only 2 or 3 days and ship it back right away. That made me feel a little better. 6) ???? I have not received it back yet (should be soon), so I don't have a final recommendation on this lens. My sense is that it will follow the "worth what you pay for it" adage. It will have taken a large investment of time (actually, waiting), but in the end I hope to have a pretty good lens at a relatively bargain price. There have been several times that I wanted to give up and just go buy the Nikon, but not being a professional, it's really hard to justify paying $1200-1300 for a single lens. Otherwise, the lens is really nice. It's nice and compact for what it does, and what several have complained about as a "really loud focus noise" doesn't seem bad to me at all. It does have some pretty serious distortion, especially at wide angle. It's a complex moustache distortion which isn't correctable with Photoshop's built in correction. I did send in photos to the creator of PTLens, and he calibrated the lens and integrated it into the PTLens plugin (and standalone version). With that, your photos can be essentially distortion-free. It's really impressive how well it works. Of course, I used the lens for weeks before I really noticed the distortion. I took a picture of brick wall and couldn't believe how bad it was. Unless your photo has a continuous horizontal element, you're unlikely to even notice this. I wish my review could be more conclusive, but I'm feeling ambiguous at this point. Hope that this helps someone trying to decide on this lens. 2115|R22BSZ7GG2IB37;2115|R9IR84M7B7Q3A;2115|R2155R86RF2CWJ;
