【Used - Like New】VILTROX EF-M2 Ⅱ Speed Booster Thank you for viewing. I purchased this item new to use EF lenses with a Micro Four Thirds camera. I used it for about two days before buying a different camera, so I am now selling it as it is no longer needed. Operation has been confirmed, but please understand that this is a no-claims, no-returns sale.
