The User's Review: Vivitar Auto Telephoto Close Focusing 135mm 2.8 Lens
This lens is long in both size and name. Its name is long and correct. Due to its image scale up to 1:2 in a 35mm camera, Vivitar uses the right term 'close focusing' rather than 'macro' (macro should mean, at least, up to 1:1, I believe).
This lens is built solid, with metal barrel and rings. If you have one with any kinds of mounts, the lens is easy to be used on a mirror-less digital camera via a proper mount adapter.
