your order was shipped today BTW. In fact Cone Assemblies can be purchased seperately, and once calibrated it's simply a matter of loosening 4 knurled head thumb screws (by hand) to change from one lens to another... no need to re-calibrate. The Bellows Adapter is in progress, but honestly it's a ways off. On the other hand, our Shift Adapter will be ready around the 1st of December.
Happy shooting, and please post some of your "keepers" on our web gallery.
