Tamron 28-50mm f/3.4-4.5 (07A) Adaptall II lens . A compact wide to standard zoom with a 58mm filter thread This lens is one of the Adaptall II mount system so it can be adapted to fit almost any camera body. Even modern Chinese manufacturers are making new mounts for the micro 4/3 cameras digital cameras. Measures just 50.7mm with a mount attached and weighs 297g. It has a close focus (macro) mode that has a Macro Mag. Ratio of 1:5 at 50mm. Would make a good portrait lens for micro 4/3 users or a decent landscape buildings lens for full frame users.
The focusing ring is smooth, zoom a little stiff at the 28mm end. Optically no fungus or scratches but signs of internal cleaning on the easy to access front elements. Could do with a reclean to just buff up the glass and make it prestine again. Aperture blades clean and quick to respond - free from any sticking. SMall dent on outside of filter rin
