Beautiful and perfectly functioning Zeiss Tessar f 4.5 150mm lens in a Acme shutter. This is gorgeous lens and all around solid performer. Recent (two years ago) CLA and mounting from Nippon. Glass is free and clear and perfect. Shutter sounds spot on. I have too many 150's to reason hanging on to it so to you it goes! $150 + shipping and Paypal CONUS only!
