Tamron AF 17-50mm F/2.8 SP XR Di II VC Review
25 February 2010
Conclusion: A hood (petal style) which mounts on the lens using a bayonet fitting is supplied with the lens. The front of the lens is threaded for 72mm diameter filters and the lens cap is a "center squeeze" design which makes it easier to remove and replace with the lens hood mounted.
Tamron SP AF 17-50mm F/2.8 XR Di II LD ASPH (IF) Lens Review

Summary: Putting aside such glaring issues as build quality, noisy and slow AF, Tamron SP AF 17-50mm f/2.8 XR Di II LD ASPH IF is capable of producing pretty good results. Unfortunately, the performance is rather inconsistent across the zoom and aperture ranges. Hence if you're holding high hopes for the lens, you might get disappointed.
Conclusion: With the exception of the distortion at the wide end, this is a very competent lens and a considerable jump up from the general standard of kit lens that it would replace. There is little else that lets it down and good resolution across the frame that is acceptable even when the lens is used wide open commend it. The only other place it could be improved is in the autofocus system where Tamron really do need to get a sonic motor.
Pros: Good resolution and control of CA, Nice build, an improvement for Tamron, Consistent through the focal range
Cons: Distortion at the wide end., No supplied case or pouch.
Excerpt: Part 1 - Introduction, Specifications and Autofocus Part II - Distortion and Vignetting Part III - Image Quality Part IV - Macro and DOF vs. Aperture Part V - Conclusions The initial impression of the Tamron SP AF17-50mm F/2.8 XR Di-II LD Aspherical [IF] is that it's a solid lens. It feels "dense". Not heavy, but it gives the impression of solidity. The body seems to be made of a composite (plastic) material and the finish is in low-reflectivity black with a gold ring.
Excerpt: Like Canon's EF-S Lenses , The Tamron 17-50 provides an image circle that is large enough for APS-C (1.5x/1.6x FOVCF) sized digital SLRs sensors. Being sized for a smaller-format sensor allows a smaller design to be used. Measuring 2.9 x 3.2" (74 x 82mm)(d x l) and weighing 15.2 oz (430g), the Tamron 17-50 is an ideal size for these smaller digital SLR bodies. It balances and handles very nicely.
Excerpt: DSLR photographers looking to move up from the distortion and limited sharpness and speed of their kit lens will welcome this new wide-to-medium tele. Tamron has toted out big-gun technology for its 26-78mm equivalent ($450, street). This Di II (digital only) optic boasts a high speed, constant aperture, two aspheric elements, internal focusing, one element of low-dispersion glass, and another of a super low-dispersion XR (Extra Refractive Index) glass for, the company...

Some of the new products (Di II series) were designed exclusively for digital cameras with the typical APS-size sensor, while others (Di) are multi-platform...
Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] (Nikon) - Review / Test Report
1 February 2008
Conclusion: The Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] is a very serious performer capable to deliver some of the best MTF50 figures to date in this lens class. Vignetting and distortions are about average for a lens in this class. CAs are very high at 17mm and 24mm. Mechanically the lens isn't top notch but it compares very well here to other third party lenses. AF accuracy could be a little better on the Nikon D200.
