Tamron SP AF 17-50mm f2.8 XR Di II LD Aspherical IF Lens 

This Tamron SP AF 17-50mm f2.8 XR Di II LD Aspherical IF Lens lens offers an f/2.8 maximum aperture throughout the entire zoom range, to ensure stress-free photographic shots at all focal lengths and distances. Additionally, a broader photographic expression through the use of faster shutter speeds as a result of the maximum aperture offers enhanced photographic pleasure.

WARNING: Not compatible with “full-frame” (35mm size) cameras.

Note: Di-II lenses cannot be used with digital SLR cameras using image sensors that are larger than that of an APS-C size imager (e.g. 1D series), or with 35mm film SLR cameras.

Optimized for Digital SLR
The use of XR (Extra Refractive Index) glass optimizes the overall distribution of optical power, and also reduces various aberrations to the absolute minimum while achieving remarkable compactness. In addition, suitable positioning of two hybrid aspherical elements serves to maintain imaging performance and to shorten and compress the entire optical system.
LD Glass
An LD (Low Dispersion) glass element is used to accomplish effective compensation of on-axis and lateral chromatic aberrations, a critical factor for enhancing optical quality in digital photography, in order to achieve outstanding optical performance over the entire zoom range.
Enhanced Peripheral Illumination
Peripheral light fall-off is minimized when compared with that of conventional lenses for film cameras, so images are uniformly bright from the center to the periphery.
Internal Surface Coating to Reduce Ghosting and Flare
By employing “Internal Surface Coatings” (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coating technology on ordinary elements, ghosting and flare due to the reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum.
Zoom Lock Mechanism
The Zoom Lock prevents unwanted barrel extension when carrying the lens/camera combination.

    Let’s face it, the standard kit lenses you get outta the box with all low to mid-range dlsr’s are pretty shameful to a discerning photog on a budget, the Tamron 17-50mm is a superior alternative to kit lenses, producing sharp clear and relatively aberration free images. With a low f2.8 aperture throughout the focal range, it can isolate and create some stunning portraits and still-life shots, while on the other end It can be used to create great landscapes, and in low light can be used to capture some great intimate and spontaneous moments. For the price this is a fantastic lens.
