Use Open aperture to make your subject stand out from its background

The largest diaphragm opening of a lens delivers the shallowest depth of field. This 17-50mm has a maximum aperture of F/2.8. This opening can be used to make subjects stand out against a blurred background. Only fast lenses bring out this effect fully, especially with APS-C sized sensors where the depth of field is rather high due to geometrical reasons. Fast lenses like this 17-50mm help to fully maximize the creative possibilities of photography.

Description

This Tamron 17-50 F/2.8 Di II XR is an extremely high-quality standard zoom with a high luminosity of 2.8 over the entire focal length range. It belongs to the Super performance (SP) class of Tamron lenses distinguished by ultra high optical and mechanical quality. The high luminosity that this lens offers is ideal for low-light conditions and professional image composition. The result is images with smooth, even bokeh (background blur), where the subject is virtually released from the background.  Apart from the unlimited possibilities that this lens has to offer, it is the quality of your images that stand in the focus.

The world´s shortest minimum focus distance of only 27 cm was achieved, by using 3 XR glass elements (Extra Refractive) in the front group coupled with a new mechanical design, whilst at the same time keeping the construction compact. The maximum magnification ratio of 1:4,5 and a weight of mere 430 g are also a worldwide top*. Image defects are kept at an absolute minimum through the application of aspherical elements and LD (Low dispersion) glass as well as a special coating of internal glass surfaces (Internal Surface Coating). The result is high-quality extremely sharp and excellent images.

*based on lenses of the same class and F/2,8

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).
