Tamron SP 85mm F/1.8 Di VC USD sample images
The Tamron SP 85mm F/1.8 is a bright portrait lens for SLR cameras from Nikon and Canon. On APS-C models, the focal length approximately corresponds with that of a 135mm. Many photographers swear for portraits by a bright, short telephoto lens like an 85mm, and the selection for these kinds of lenses is great. The Tamron SP 85mm F/1.8, however, has something that lenses from Nikon and Canon in this brightness do not have: VC. That stands for "Vibration Control." The Tamron thus has image stabilization. That's nice to have for portraits, because you can then comfortably work with a bit longer shutter times. You also don't have to worry at shutter times of 1/60 or 1/125 about motion blur, which can occur with unstabilized lenses with this focal length. If you use this lens on an APS-C or DX camera, then that image stabilization is really indispensible.
