Digital camera reviews of Tamron AF 17-50mm F/2.8 XR Di-II LD SP Aspherical (IF) Zoom Lens for Canon Digital SLR Cameras
Digital camera Review: Best wide angle zoom lens.
Summary: 5 Stars
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
Digital camera Review: Canon who?
Summary: 5 Stars
This is my first ever Tamron purchase. Apparently in the past they made mediocre lenses, but that seems to have changed recently, and this lens seems to confirm it. Images are SHARP, SHARP, SHARP. Color is good, contrast is good, and there's almost no picture degradation on the outer edges, even at f/2.8. No color bleed, no fringing. It's almost too good -- I can see every little skin cell and blemish on someone's face. I can see every little grain on my grandma's leather purse. I can see every little teeny leaf in a far-off tree. It's a vast improvement over Canon's standard 18-55mm kit lens, and better than Canon's mid-grade too. Granted, I haven't tried the famous L series lenses from Canon, but this is about half the price and likely as good.
Cons: everyone complains about the focusing noise. That doesn't bother me at all -- I get used to almost anything. If silence is a factor then go with Canon. Otherwise, the Tamron AF17-50mm f/2.8 does about everything you'd ever want.
Digital camera Review: Decent lens but some quirks...
Summary: 4 Stars
OK, I wanted a 17-55 mm zoom to complement my Sigma 35-300 zoom for my Canon Rebel XSi. After trying both the Sigma 18-55 mm f2.8 and this lens I chose the Tamron. While it is not quite as sharp as I like (Sigma has soft focus issues too) I could not justify the price of a Canon L series lens. This lens has met my expectations. It is reasonably fast. The autofocus is a bit noisy but not overly so and it allows me to have a lens that is an effective 28-88 mm zoom when factoring in the 1.6 crop factor for the APS-C sensor in the Rebel. There seems to be a bit of distortion when shooting at 17 mm at f2.8 but it is not extreme. Is it as fast and as tack sharp as a Canon L? No, but for the price it is a very good lens. The only complaint that I have with it is that it zooms in the opposite direction from Canon and Sigma lenses. For the price, I am happy and now I have a lens that allows me to shoot in low light without a flash in most conditions.
Digital camera Review: Decent quality, average construction
Summary: 4 Stars
I bought this very popular lens after considering other brands' alternatives and reading the reviews. This is my primary walkaround lens that I use when I don't want to carry heavy or expensive gear and need pictures that are "good enough" for the purpose, which is what this lens produces. For situations where image quality is of high priority, I rent L lenses.
Pros - light, very versatile, inexpensive relative to alternatives
Cons - front-focusing and construction. After less than a year, the front element has begun to wobble and I'm sending the unit for repairs.
Digital camera Review: Definitely satisfied
Summary: 5 Stars
This lens has lived up to it's reputation! Colors are vibrant and sharpness is outstanding. If you're considering this lens, it's a no-brainer...Get it.
