Excellent condition - check out the scopetronix web site for more information. Just remove the rubber eye cup and a threaded connection for a digital camera (Nikon I think) appears, making this an easy to use eye piece for digital pics. I just got this in on a trade and I already have a 14mm Pentax, and don't have a Nikon camera, so it is excess to my needs.
Looks like these are $109.00 new. Optically and physically this one is pretty hard to tell from new - just some very minor set screw marks. My price is $70.00 shipped to you cont. U.S. Paypal is ok (no upcharge) or money order.
Email with any questions.
Thanks for lookin!
