I am a new member over here and just purchased the Panasonic Lumix G5. I am a long time Nikon user and have lot of G lenses. In order to use my G lenses with the extremely portable G5 I bought the Rainbow Imaging adapter from Amazon. Although the adapter gets the job done it is not at all snug with either the lens or the body and I feel somewhat uneasy using it. Do any of have any experience with any other adapters which have a snug fit? I know there are expensive adapters like Novoflex but they are way beyond my budget at this time.
