Fuji and Zero,
Just a thought, are you going to group the newcomers with seniors who have experience in which system. I’m pretty familiar with Canon system. Even played (but not owned) a 1DsMkIII, but if you ask me to operate a Nikon, I might fumble around the menus, although i should be able explain the exposure triangle, ISO, shutter speed, aperture. So it’s fastest for me to help newcomers with Canon system.
But i understand this would cause more work for you two. Thank goodness for people like Numnumball who have experience in both
