I am likely to get a view camera, for studio tabletop (DoF control) and architec tural interiors (perspective control), and will use this with RF backs - quality is more than sufficient, and I'm experienced with RF on various marques. I am c oncerned about the prospect of an inverted image, though, and not certain I coul d get used to it. How useful are reflex finders for view cameras? All manuf's se em to offer them, including the Horseman, Toyo and Arca I'll probably choose fro m (my ideal is the Arca 6x9 Monolith) but have users found the benefits outweigh the darker image and the cumbersome handling? Opinions greatly welcomed.
