I purchased a Tamron AF 60mm f/2.0 SP DI II LD IF 1:1 Macro Lens for Canon Digital SLR in May of 2010.  Hoya 55mm Ultraviolet UV(0) Super Multi Coated HMC Filter was installed on it since day one.  Lens looks new, works perfect – no visible signs of wear and tear.  I’m upgrading to Canon full frame sensor camera and this lens works only on APC’s.  Make me a reasonable offer(Considering Amazon sells them for $524 new and used on the Ebay go for about 425)!
