The Tamron 35-150mm F2.8-4 Di VC OSD is a standard zoom lens for Canon and Nikon full-frame DSLRs. Its somewhat unusual zoom range, combined with a minimum focus distance of 45cm, makes it particularly well suited for portraits, ranging from environmental studies to close-ups. Thanks to its compact size and light weight it is also a perfect travel companion. It offers an unusually fast aperture for such a range, from f/2.8 at wide-angle through to f/4 at the telephoto end. The lens incorporates Tamron’s Dual Micro-Processing Unit system, which assures optimal autofocus performance and effective vibration compensation, allowing for sharp handheld shots.
