Thanks folks,
My Summar is one of the nice ones (glass-wise). Just has a dinged front ring, but the nicest glass I've seen on one. It has one issue, separation? or similar around the edges of the front elements. Its just the junction where glass meets the barrel, so "separation" might not be the correct term. I'd think its paint loss, but there's no paint or anything floating around in this lens. I suppose it may have been disassembled and emptied at some point in its life...Anyway, I think the "separation" contributes to some flare, but nothing at all like your average summar. I actually get contrast with this one. Like I said, its one of the nice ones. Paid a moderate price for it. Just because the glass was so darn nice.
Thanks for the tip on the older thread. I'll track it down. Its so difficult to locate all these third party hoods, adapters, and what-not these days. All the camera stores are disappearing and with them, that box of knick-knacks you can rummage through. I'm talking about multiple boxes of old series X adapters, filters, hoods, lens caps, rear caps, accessory shoes, flash cords, and every other doo-dad the shop owner threw in there over the years. I miss those boxes.
