I have the Sinar binocular and the wide bellows. But I do not have the reflex viewer and no binocular hood. I just wonder what you guys use with Sinar camera. The dark cloth with magnifier, or the binocular+wide bellows, or the complete set of binocular+reflex viewer+hood? Your personal opinion is just fine. I know we humans are all different. I'm still getting used to moving my camera to compose.
