REVIEW: Tamron SP AF 17-50mm f/2.8 VC XR Di ll LD
28 July 2011
Conclusion: This lens has turned out to be a very interesting alternative to manufacturer's own offering in this focal range. It is capable of producing images with very good resolution, especially in the centre of the image and the Vibration Compensation feature has proved itself a worthy addition, greatly increasing your chances of achieving a sharp shot.
Pros: Excellent resolution in the centre at most apertures and focal lengths, Vibration Compensation is very effective, Good value for money
Cons: Falloff in resolution at 50mm and f/2.8, Flare control
Excerpt: Most of the alphabet seems to feature at some point in the Tamron's full title, but these abbreviations promise plenty of features. SP signifies Super-Performance, based on three XR (Extra-Refractive) elements, an LD (Low-Dispersion) element and two Aspherical elements in its construction.
Conclusion: The Tamron 17-50/2.8 Di II VC is a viable alternative to the Canon EF-S 17-55 f/2.8 IS USM , ( compare prices ) ( review ) at a price that’s about $450 lower. The image stabilization is very effective and overall performance is good, though not quite as good as the Canon lens, especially wide open and at the edges of the frame.
Excerpt: This high-speed digital only ultrawide ($650, street) upgrades Tamron’s nonstabilized 17–50mm f/2.8 ($460, street). Like the earlier lens (which remains in the lineup), this version uses an Extra Refractive (XR) element, two elements of low dispersion, and three of compound aspheric glass—adding up to a remarkably compact yet sharp and mostly distortion-free f/2.8.
Summary: * Length and weight values given are for Nikon cameras (with built-in AF motor). ** Specifications, appearance, functionality, etc, may be changed without prior notice.
Pros: Very well built, Comfortable controls, Capable VC system, Fast f/2.8 maximum aperture, Produces beautiful results when stopped down, Appealing focal range, Half the price of it's Nikon and Canon competitors
Cons: Quite soft when wide open, Small amount of visible CA, I felt the zoom ring had a bit too much resistance, AF and VC systems make a good amount of noise, Some front focusing was noted while capturing indoor portraits
Excerpt: Based on the quality-for-the-price ratio of the non-VC Tamron 17-50mm f/2.8 XR Di II Lens , I had very high hopes for the Tamron 17-50 VC. Taking the good image quality of the non-VC 17-50 and adding vibration control to it sounded like a recipe for success to me. A recipe that should close the feature/benefits gap between it and the excellent Canon EF-S 17-55mm f/2.8 IS USM Lens .

Summary: Tamron's 17-50mm F/2.8 lens is a good upgrade if you own an entry-level or middle-of-the-pack camera, as it can provide a noticeable jump in image quality, as well as better performance when shooting in dim lighting conditions.
Pros: F/2.8 aperture, Good upgrade for entry- and mid-level camera bodies
Excerpt: The Tamron SP AF 17-50mm f/2.8 Di II VC is a standard zoom lens designed for primary shooting duties. The lens aims to stand out for its f/2.8 designation, which is a fast, open aperture designed for low light shooting. The SP AF 17-50mm f/2.8 Di II VC is positioned as an alternative to kit lenses by first-party manufacturers like Canon, Nikon and Sony. In the case of Nikon, the Nikkor DX 18-55mm is popular choice, particularly with first-time camera owners.
Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] VC (Nikon) - Review / Test Report
15 March 2011
Conclusion: The Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] VC is a very promising lens based on its specifications. However, it falls somewhat short of the high expectations especially when considering the excellent performance of its non-VC variant. The biggest weakness of the lens is the rather soft corner/border performance at large aperture settings. The quality increases when stopping down and it's certainly possible to achieve very high quality results.
