Adapters for reverse mounting of lenses are readily available on 'bay for less than $10 (see http://shop.ebay.com/i.html?_nkw=reverse+lens+adapter). They mount lenses via their front filter thread so make sure you have a match against your camera body AND against the filter size of your lens. Author uses a combination of two adapters - a filter thread to Exakta body adapter and an Exakta lens to 4/3rds body adapter to mount the Orestegon to the L1. | Adapters for reverse mounting of lenses are readily available on 'bay for less than $10 (see http://shop.ebay.com/i.html?_nkw=reverse+lens+adapter).
