TAMRON SP 17-50MM F2.8 XR DI II VC LD CANON
Warranty:LIMITED 3 YEAR
Make the most of your light. With perfect stability.
Even sharper high-speed, wide-angle photography in low light
This lens covers the extremely popular 17-50mm focal length range (equivalent to 26-78mm in the full-frame 35mm format*) making it extremely versatile. It delivers impressive sharpness and striking contrast over its entire range of focal lengths and apertures. this lens delivers a fast f/2.8 aperture over its entire range of focal lengths for maximum creative flexibility. At its maximum aperture of f/2.8 it produces beautiful images enhanced by shallow depth of field and excellent bokeh (i.e. smooth, natural transitions in the out-of-focus areas of the image). Equipped with Tamron’s state-of-the-art, tri-axial Vibration Compensation (VC) image stabilisation mechanism, which controls the effects of camera shake, this lens provides more opportunities for sharp handheld photography at the slow shutter speeds needed when shooting in low-light conditions (e.g. night or indoor scenes), dramatically enhancing the user’s level of photographic freedom. Three compound aspheric elements, special LD glass, and BBAR coatings ensure superb correction, colour fidelity, and freedom from flare. A minimum focus distance of 0.29m (11.4 inches) offers exciting close-up opportunities. * Using a conversion value of 1.55x.
Super Performance series
Performance takes priority for superb image quality
This line of ultra-high-performance lenses is designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. The foremost priority is achieving superior performance parameters – high design standards take priority over cost constraints. As a result, Tamron SP lenses feature innovative designs that have established an enviable reputation for excellence amongst demanding photographers.
VC Vibration Compensation
Compensates for camera blur on long shutter speeds – for sharp images in much lower light Tamron’s unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The mechanism employs a tri-axial system in which three driving coils move internal optical components within the VC lens electromagnetically. The VC lens elements are held in place only by contact with three ball bearings – which in the latest Tamron VC lenses are ceramic – achieving smooth movement with minimal friction. The simplicity of this mechanical structure is also one of the secrets of Tamron’s compact lens sizes.
Compact size with a filter thread of Ø72mm, while delivering both a large f/2.8 diameter and VC
The addition of an image stabiliser tends to increase the size of a lens. As this lens is a large-diameter f/2.8 zoom, the optical image stabilisation system is also relatively large compared with other VC models. However, through improvements to optical, mechanical and VC designs, the filter thread is a compact 72mm.
Useful when carrying the lens/camera over the shoulder Another original Tamron mechanical engineering concept is the zoom-lock mechanism, which prevents the weight of the lens barrel from extending the lens when carried on the camera pointing downward. This eliminates the danger of accidentally knocking the lens while walking around and enhances responsiveness in the field. Simply zoom the lens out to its widest focal length and use the sliding zoom-lock switch to lock the barrel in place.
