Moving to a mirrorless system, and I need to make room. Selling my Backscatter M52 Wide Angle Wet Lens. It is in excellent condition, a couple of very minor scratches that do not affect picture quality. This is the older version, and is not compatible with the AOI Quick Release System. On the plus side, you can add a "No Burp" O ring from Backscatter and burp the lens in the camera bucket on the boat. The O ring keeps the water from coming out so you won't need to burp it underwater and risk dropping it. Additionally, it allows for split shots since the water does not drain out. Asking $300.00, which includes shipping to lower 48.
