This is an Olympus 4/3 to m4/3 adapter, proper camera communication with the excellent Olympus 4/3 lenses. This unit was new in June, used on one specific lens that I no longer own. It is in cosmetic 9+ condition and functions perfectly. Original packaging. $85. Flat rate USPS priority mail shipping to U.S. addresses, I can ship to Canada too (for an additional $5). I prefer Pay-Pal for payment. Contact me by PM here.
