Yessir, I'm quite content with my Minolta kit. For years I have concentrated on the SRT-era items, with a few later items, as I find them quite useful. For example, the 400mm MD APO Rokkor-X with matching 2X Apo Rokkor Tele-Converter, is much more useful to me, than the 80cm F/ll RF Mirror Rokkor (which I don't own). The 100cm F6.3 RF Rokkor would be like finding the Holy Grail, but, hauling a fifty-pound wooden case and lens for birding with my Wife, would be a struggle, and quite limiting, too, I would imagine.
Amazing to see such an item is such good condition. I surmise it was used for Law Enforcement, from the background given by the seller. Probably could tell some stories. Would look great hooked up to one of my SRM's and my Zone VI wooden tripod. 😱
