I've tried different methods of putting the lens in the adapter, and it still won't work. Once the lens is in the adapter, the focus ring moves, but when the lever is pulled to lock the lens in (for standard mount), it's completely immovable. In fact, the lever lock does not fully engage.
If a different lens adapter altogether could work with these lenses, that'd be great. In fact, if you could let me know once you get yours, or if someone who's had experience with this write in---
I'm not sure if my adapter is from Les Bosher.
