New version with the compression ring rather than the set screw. Excellent condition with original box. Does not degrade image and is noticeably better than any other type barlow that I have observed with. It does have one very small set screw mark my camera would not be able to show. That is all that keeps it from being listed as mint condition. $70 includes shipping CONUS. I accept paypal ( no extra fee ), MO, or check. MO or checks must clear bank before shipping.
Have a happy holidays!!!
