Focus Daniel-son

The focusing method of stereo cameras will make a difference in the quality of your pictures. High quality cameras, like large format, move the entire lens when focusing. Moving the film plane accomplishes the same thing. The early Mamiya 6 medium format camera focused in this manner. Lower quality cameras move the front element of the lens (see lens diagrams in previous post). If the lens elements stay aligned and are not twisted by focusing, better image quality results. The Colorist focuses the front lens elements.
