No (and this is the confusing thing for me), its not a mirror lens. The only Tamrons I had seen in the past were the Mirror version.
Me too, didn't know Tamron did a non mirror 500. I'll be interested to hear how it works. I do have a Tamron SP 500 f8 mirror which as mirror lenses go is quite nice...better than the Canon FD version by a long shot. Don't use it much though, just not much call for it I guess.
Various Canons and Nikons. A Mamiya and a Bronica. A couple Brownies, and a Couple of Argus' (Argi?)
