Vivitar 28 - 85mm F/3.5-4.5 MC Macro Focusing Zoom on Sony Nex — Simon Hawketts' Photo Blog
This is a review of the Vivitar 28 - 85mm compact, variable aperture zoom lens when used on a Sony Nex camera. The version of the lens I have is fitted with a Minolta MD mount, although they were available (as all Vivitar lenses were) with other mounts fitted.
