For Sale Petzval Gem Tube Lens - 140mm Focal Length f/4.5 - 110 back focus - covers 4+ inches

[luvcameras]

Very nice Gem Tube Lens. Focal length is about 140mm with a 110mm back focus. Image circle just over 4 inches. Probably made to cover 1/4 plate. Glass is crystal clear. Throws a sharp, crisp image on ground glass. Speed is F/4.5. Great lens to play with on 4x5 or watch it swirl and vignette on larger formats. Or with its short back focus, mount to smaller formats. No flange but threaded. Barrel is 3.5" tall. Glass diameter 1 5/8". $ 135 shipped in US - $ 150 elsewhere.

Perfect 17 year Ebay feedback http://feedback.ebay.com/ws/eBayISAP...ab=AllFeedback

Thank you
Dan

On gem lenses, the thread is meant to be on the sitter side, since they threaded into a brass lensboard from inside the camera in groups of 4 to 9 lenses per camera. Still quite a good deal and a fun lens to shoot with...just thought I'd give aheads-up to buyers.
