Here is a Tamron 172DM lens, as shown, for the type of lens mount used on the old Minolta Maxxum 35mm film SLRs, the Konica-Minolta DSLRs, and the Alpha mount used on the Sony DSLRs.  Note that there are some Sony cameras now that carry the Alpha name but use a different mount, so please make sure the camera you intend to use this on has the actual Alpha mount. If you need an economical long telephoto lens, this might be just what you are looking for.  It comes with the Tamron front and rear caps.  This lens is in excellent condition both cosmetically and optically. Blades are oil free and snappy. Optics are clean and clear. See photos.

Comes with Hoya UV(0) filter and Tamron BF4H Hood.
