Amazon.com 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. - Focal length: 17-50mm

 Good lense for a good price October 8, 2008
Blue Sky
Pictures taken on my 30D are sharp. Focus is fast enough for me under most of light conditions. The focus noise is there but doesn't disturb me. It would be nicer if it's quieter but not critical for my amateur purpose. Overall a good lens for a good price.
Great Lens to replace "Kit Lens" October 6, 2008
Richard C. Deyoung (Texas, USA)
I recently replaced my Canon EFS 18-55mm Kit lens with the Tamaron. What a difference. Photos are much sharper and the focusing function is much better than the Canon. Quality of the lens is much better and its operation smooth and positive.
No problems in its use with my Canon 40D body.
Would recommend this lens to anyone.
 Sharp, fast lens for the price October 1, 2008

I have had this lens for a little over a month now and absolutely love it. My purposes are very specific, so I won't be able to offer insight on a variety of applications for this lens, but here goes.
Purpose:
Replace slow/soft Rebel kit lens with a faster/sharper piece of glass without busting the budget.
Shooting conditions:
Bedroom with 60w overhead light of a moving baby (I typically shoot at ISO 1600 1/60 due to the movement of our little guy).
To start, I have used the lens in other situations and have been very pleased with the results, but I haven't taken a broad enough selection of shots to get a good feel of how it handles in various situations. With regards to the indoor portrait shots, this lens has handled beyond my expectations.
Speed: Obviously the extra speed when compared to the kit lens helps tremendously in my shooting situations. I have tried shooting with the kit lens and simply wasn't able to get a fast enough shutter speed to capture what I wanted without blur.
Focus: The focus is fast enough to allow me to catch our little man mid yawn or as he shifts into a humorous position. I've yet to miss a shot because of it. The focus is a bit loud though (which is why it got 4 stars instead of 5). For me, the lens gets a 5 of 5 as my situation doesn't demand a quite lens, but it would be an issue for those willing to invest the approx $1200 for the canon version of this lens, or if you need a very quiet lens for where you shoot. Everything I have read about the canon is that the focus is near silent.
Sharpness: The lens quality has blown me away again. I say again because my first experience with a Tamron lens was the 90mm Macro lens that I have been using since 2003. It was my experience with that macro lens that gave me the confidence in the build and glass quality of Tamron lenses. I have taken that macro lens on all sorts of hikes and journeys, and it still performs flawlessly. Regarding the 17-50, the images are extremely sharp and crisp, the depth of field is beautiful (I'm a huge fan of depth of field coming from the macro world, so take that with a grain of salt).
Build: As mentioned in my discussion of sharpness, the build feels great. I feel more than confident to toss this lens in my bag and go on a hike, bringing the lens out in pretty much any condition without hesitation. Me being confident in my equipment allows me to take better shots.
Overall I have been very pleased with this lens and how it fits into my shooting circumstances. I would, and have, recommended it to other photographers who want good quality glass, but don't have the money to go all out. This lens will undoubtedly last me several years.
Great lens for street photography September 24, 2008

I've had this lens for about 4 months. Couldn't be happier. Most of the photos on my blog were snapped with it.
