Steinheil 135mm 3.5 Auto Tele Quinar

[RAS61]

Just bought what looks like a minty version of this lens on Ebay for what I think was a very reasonable price. I've heard positive comments about the "Q" series lenses, so thought it would be fun to try one...although I must admit I think they look great, and wanted one for that reason alone! I haven't been able to find any detailed or in depth reviews of this model, so was hoping for some feedback on their characteristics and what I can expect.

Thanks for the help!
