An Extraordinarily Sharp Lens!
I'm a pure Canon lens user for the past 3.5 years. Currently using EOS 40D. This is my very first third party lens & initially was quite skeptical. After thinking it over, I went ahead to give it a try because I can't afford the Canon EF-S 17-55mm f/2.8 IS USM.After playing with the new Tamron lens for almost two weeks, here's some of my 2 cent comments:Good News first (wow so many don't know where to begin):-Great optical performance! All photos taken are really sharp.-Accurate, consider fast and consistent autofocus.-Zoom ring isn't cramped or stiff, easy to turn (opposite direction of Canon lens).-Surprisingly at 17mm I hardly can see any barrel distortion!-I can't detect any chromatic aberration & Vignette problem. All photos look clean & accurate. But it doesn't mean they are not there. Maybe I need to get my eyes checked. :-)-Nice weight (lighter than my Canon 24-105L) & feel, will be my new walkaround lens...

Product Description
The new SP 17-50mm F/2.8 XR Di II VC covers the very popular 17-50mm focal length range (equivalent to 26-78mm in the full-frame 35mm format) making it extremely versatile. Its wide aperture and outstanding performance provide practical advantages in low-light shooting and aesthetic image control, thereby enriching the user's range of creative expression. The new lens delivers impressive sharpness and striking contrast over its entire focal-length and aperture range, and at its maximum aperture of f/2.8 it produces beautiful images enhanced by shallow depth of- field, and smooth, natural transitions in out-of-focus areas of the image (i.e. excellent bokeh.) The new lens is equipped with Tamron's proprietary Vibration Compensation (VC) image stabilization mechanism, which controls the effects of camera shake in three planes. VC provides more opportunities for sharp hand-held photography at the slow shutter speeds needed when shooting in low-light conditions (e.g. night or indoor scenes) dramatically enhancing the user's level of photographic freedom.

Great lens for the price
I received this lens a few days ago and immediately started using it. The lens came with a lens hood and caps only, no carrying pouch. The lens is slightly bigger and bulkier than my 18-70 Nikkor that it is replacing. It feels great in the hands and in the camera, I can feel the quality. The lens focused accurately and speedily. I can't comment on its speed versus the non VC version, but its faster than my 18-70 Nikkor (as it should since its $300 more expensive). It locked on in low light pretty good too, something I had trouble with in my 18-70. I tested the VC out and found that the VC has a delay of about a second before taking effect. You will notice the effect because the viewfinder will have a slight jerking motion before taking effect. The VC worked quite well though, taking sharp pics most of the time (if done properly) down to 1/8th second. This lens is TACK SHARP, even at F2.8 it is very sharp.The zoom ring comes with a zoom creep lock that works at 17mm, but...

A very good lens with some shortcomings that you may be able to live with.
The title of my review pretty much sums it up. The two major features of this lens are its constant aperture of f2.8 at all focal lengths, and the new VC (anti-shake) feature. The previous version of this lens was superb, but lacked stabilization, so the VC is a welcome feature.Design/BuildIt's a very well built lens with a metal mount. Its not pro-quality, but definitely better than any kit lens I've owned. I'd give it a solid 4 out of 5 stars for build quality and design. It's quite a bit thicker than the previous version, but not much heavier. It looks huge on my D80, but its not too heavy so it works well and balances perfect on a D300.VCThe vibration compensation works very well. It works just as effective as any Nikon VR lens I've owned. No complaints on the effectiveness of the VC system. Some people reported it as loud when the VC motor kicks in, but I found it to be acceptable. Not as quiet as the Nikon VR2 system, but definitely...
