These are both very uncommon. ( I'm not saying rare, everything on Ebay is "rare" , whatever ) All lenses featured are funguz, haze, and all that stuff free! The 90mm macros have been around and reputed as being very good, but the only record of an OM mount you will find online is from another one I had. It really is that uncommon. This one is in very good shape. Very snappy aperture, turns like a smooth brick (in a good way, very precise for macro work). The cap is original panagor, the bottom cap is the biggest and heaviest OM cap I've ever seen but not sure if it is panagor or not. The hood is just a Hoya I grabbed to watch for flare. $200 for APUG members. (Price reflects that these in OM mount basically don't exsist, only $800 Olympus made macros) Review. http://www.pentaxforums.com/userreviews/panagor-90mm-f2-8-macro-pmc.html Vivitar 135mm is a cousin of the 90mm. He could just about call it a macro lens because it focuses about as close; close enough to take pictures of bugs. While Minolta is a more common mount, this lens is anything but; it is unfortuante more of thess were not made! Great lens. Rear cap, and a ring from a rubber hood and plastic cap that fits on (sorta ghetto but better than nothing) Asking $150 for APUG members. I apologize the pictures of the Vivitar 135mm are awful. I have to retake them later when I'm at home with my stupid digital camera that is an utter joke. Oh I've got a 50mm 1.7 Minolta MC later model if anyone wants it. I just don't use it, Excellent condition $25 shipped CONUS.
