Score of the week, well maybe. Today I picked up a Minolta X-370 with a 50mm 1.7, and a Tele-Rokkor 200mm 3.5, from a coworker. For the princely sum of $25 USD. Everything in excellent condition. I already have a 50mm Rokkor 1.7 that I'm pretty happy with. This 50 I'm not familiar with. There is a plastic "switch" to lock the lens as f22, but it doesn't seem to do anything more. What is this for? Just to lock it at f22? Cant say I have ever seen this before, but most of the lenses I'm drawn to these days are way before my time anyway. The next question. How much weight cant he 5N mount handle? The other lens is a 200mm f3.5 Tele-Rokkor-QF. This thing is beefy, built in sliding shade. All metal, only plastic is the rear cover. Weighs in on the kitchen scale at about 1 pound 10 ounces. Didn't get a front cover, but came with a pouch. Also no covers for the 50 either, but the camera came with the old school leather case to protect the whole package. So can the nex handle that lens on a tripod, without finding some type of collar? It's almost impossible for me to get a decent shot hand held.
