Please Note:

For all other cameras--Hasselblad, Mamaya, Leica, Olympus, Pentax, Fuji... even though you will be shooting manual or auto-exposure, you still get to choose your Dedicated base brand from either of the 3: Nikon, Canon or Panasonic. So, although you dont need Dedicated control for your camera select any one of the 3 dedicated base brands that would work best for you some day.

For example if you are buying this for your Leica but you also have Nikon, choose the Nikon Dedicated base model.
