Tamron SP AF 17-50mm f/2.8 XR Di II VC LD Aspherical (IF)

The Tamron SP AF 17-50mm f/2.8 XR Di II VC adds Vibration Compensation to the popular fast-aperture standard zoom. Designed for APS-C DSLRs, it maintains the constant f/2.8 aperture, providing better handheld performance in low-light conditions. The optical construction includes LD and aspherical elements to manage distortions, while the VC system provides up to four stops of stabilisation, which is particularly useful for video and slow-shutter stills. When purchasing used, it is vital to test the VC mechanism; ensure the image 'settles' in the viewfinder without jumping or making excessive grinding noises. SDS checks the zoom mechanism for smoothness and inspects the front and rear elements for coating wear. The lens barrel is slightly larger than the non-VC version, so check for any impact damage to the plastic housing.
