A few years ago, I wrote an article about the CAMBO X2 Pro and Nikon D800 and included some typical photography examples. I’ve just upgraded my set with the new Cambo Actus, the excellent Nikon D810 and some “new” interesting lenses never tested by DxO :-).

The ACTUS has both similarities and differences with the Pro X2: same concept (lens panel – body with bellows – camera mount) with a great difference. The interchangeable front lens panels, which are available in the following formats: Copal 0, Copal 1 (on request), Hasselblad C Bayonet, M39 Leica thread, Mamiya RZ/RB bayonet, Mamiya 645 Pro bayonet, Leica R Bayonet (for mirrorless bodies only) and the Nikon-F Bayonet (for mirrorless bodies only, can only swing and tilt.
