The prices are at Cameta, with free shipping in the U.S. I got interested in this because Olympus sent me a mailing promoting it with test shots that indicated it converts the 14-42 II or IIR kit lens into a rectilinear 11mm lens - which I had not realized - I had previously thought this was a fisheye-type adapter, which didn't really interest me. I also just got my quarterly ebay bucks certificate this morning, which was for $55 dollars that I needed to spend in the next 2 weeks, so by applying it to this purchase at Cameta's ebay store, I basically paid $4 out of pocket for it. I have no idea just what sort of quality this produces, but for that price, I certainly will give it a try and report back. If the results are decent, then this will certainly serve a VERY useful purpose in providing an economical 11mm wide option, when every other means of getting 12mm or wider costs several hundred dollars more.
