In addition, portrait shots are made beautiful with the natural out-of-focus effect characteristic provided by the fast F/2.8 aperture. Additionally, a broader photographic expression through the use of faster shutter speeds as a result of the maximum aperture offers enhanced photographic pleasure. The lens boasts one of the best close-up shooting performances in the class of fast standard zoom lenses designed exclusively for digital cameras and featuring an F/2.8 maximum aperture throughout the entire zoom range, to ensure stress-free photographic shots at all focal lengths and distances.
In the Tamron 17-50mm f/2.8 XR Di II Lens, we have a very useful tool. Since it is small and light, we can take it everywhere. Since it is fast (f/2.8), we can use it in low light and indoors – and to stop action. Since it has very good image quality, we can use it for important shots. This list along with a nice general-purpose focal length range fills the requirements of a huge range of photographic opportunities (I’ll let you think of them). For the price, the Tamron 17-50 is a bargain lens.
Optically the Tamron SP AF17-50mm F/2.8 XR Di-II LD Aspherical [IF] is better than the Canon EF-S 17-85/4-5.6 IS, and though 1-2 stops faster, it lacks IS and the zoom range is smaller.
If you’re after high optical quality, a fast lens which can blur backgrounds and stop action but you don’t want to spend more than about $500, the Tamron SP AF17-50mm F/2.8 XR Di-II LD Aspherical [IF] is a lens you could be very happy with.
