Product Description
The Tamron AF 17-50mm aspherical lens expands on the popularity of the AF 28-75mm f/2.8 XR Di zoom, with a 17mm focal length that offers a wider angle of view than an ordinary standard zoom lens. Designed exclusively for digital SLR cameras with smaller-size imagers (24 x 16mm or smaller), the 17-50mm standard zoom is extremely lightweight and compact for its speed. And with a fast f/2.8 maximum aperture throughout the range, it delivers fast shutter speeds and a natural soft-focus effect that makes your photography even more sophisticated than usual.
Superior image quality
Constructed with cutting-edge Tamron elements–three elements of XR (extra-refractive index) glass, two hybrid aspherical lens elements, and one element of LD glass–this elegant piece of technology inherits Tamron’s tradition of premium image quality and compact size. By incorporating Tamron’s SP (super performance) and Di-II (designed exclusively for digital cameras) specifications, along with special internal surface coatings to eliminate ghosting and flare, you’re guaranteed to get the superior performance you need from your digital camera.
Broadening your horizons
Tamron’s SP AF17-50mm offers a wider angle than the standard 18mm zoom lenses ordinarily used with digital cameras. With a wider-angle focal length of 17mm (26mm equivalent), this lens is unbeatable for indoor photography, and for capturing full-length people shots or an entire building. The lens is also top-level in its class for minimum focus distance at 27cm (10.6 inches) across the entire zoom range, making it easier than ever to enjoy the creative combination of wide-angle and macro photography.

Best wide angle zoom lens by Linan Chen
I tested canon 24-105 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 24-105 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 priceTalk about bang for your buck! by Tristan
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 FIVE YEAR warranty, as opposed to Canon’s weak 1 year warranty. Buy me.
