Product description from Tamron
At launch 2009 Tamron wrote this regarding Tamron SP AF 17-50mm F2.8 XR Di-II LD IF VC:
"The Tamron SP designation is reserved for lenses developed with special emphasis on extraordinary photographic performance. Engineers are free to innovate in an uncommon atmosphere where optical performance comes before price, resulting in lenses that satisfy the demands of discerning photographers.
The compositional options afforded by the SP 17-50mm F/2.8 Di-II VC´s wide-to-moderate-telephoto zoom characteristics are prized by experienced photographers, rendering a picture angle range approximating a 26-78mm lens on a full frame DSLR or a 35mm SLR. A fast and constant F/2.8 maximum aperture allows cluttered backgrounds to be softly obscured, additional freedom in lowlight conditions and added viewfinder brightness. State-of-the art properties, including XR (Extra Refractive Index) and LD (Low Dispersion) glass in an optical formula employing 19 elements and 14 groups—assures sharpness, optimal contrast and breathtaking image fidelity. Its form factor and handling characteristics can be traced to the use of aspherical element design and internal focus. Tamron´s proprietary tri-axial VC (Vibration Compensation) image stabilization adds to image sharpness and further expands low-light shooting freedom by combating image blur resulting from camera shake. Tri-axial VC addresses the adverse effects of camera shake in three planes making it possible to shoot handheld at as many as four shutter speeds slower than would otherwise be possible.
The large-aperture and excellent optical performance that this lens offers is ideal for low-light photography and enriched creative picture composition possibilities. The new lens delivers pin sharp results and remarkable contrasts throughout the entire focal length range. With an aperture of F/2.8 impressive photos with smooth, even bokeh (background blur), can be shot helping to emphasize subjects by means of a very shallow depth of field.
This lens is equipped with a tri-axial image stabilizer called vibration Compensation ( VC), a Tamron proprietary development. The VC feature minimizes the effects of camera vibrations and shake of hand-held photography. The lens offers more photographic possibilities for shots at longer shutter speeds, making it ideally suitable for ” Available Light” photography in low-light conditions.
Please note that Di II lenses are made for the exclusive use on digital SLR cameras with image sensors smaller than 24mm x 16mm. Di II lenses cannot be used together with a full format or 35mm SLR camera, as their image sensors are not able to cover the entire area of full format resulting in dark corners of the (i.e. vignetting becomes noticeable). "
Compatibility, autofocus and focal length
The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens.
This lens is designed and meant for Canon and Nikon cameras with a smaller sensor (often referred to as 'APS-C') which means that the lens does not fit all camera models. By clicking on the link below you can make sure that the lens works with your camera model and you should do an additional check with your local dealer as well, before you buy the lens just to be sure.
The ability to use autofocus is available for all cameras.
The lens has a focal length of 17-50 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 27-80 mm if you have a Canon camera or 26-75 mm if you have a Niko camera.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/2,8.
This aperture value indicates that the lens is very bright. This will make it so much easier shooting in darker environments where you do not want or can use flash lighting, for example in churches or at different sports venues.
A feature worth commenting, which is also related to lens brightness, is that the brightness and maximum aperture-value remains constant regardless of focal length used. This makes it easier for you as a photographer. No matter if you are have the focus ring and focal length at 17 mm or at 50 mm the aperture value can be f/2,8.
Inside the lens there is an image stabilizer, which helps to fend off possible movements and tremors. This is very positive and can be of great help in situations and conditions where the light is inadequate and not enough for decent shutter speeds.
Filter and Lens Hood
The lens has a traditional filter thread on the front and its measuring 72 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.
If you buy this lens it will come with a lens hood, whose model name is "AB003".
