Suppose you owned a proline 1/2" or 2/3" camera. Both formats still have way too much inherent depth-of-field, compared to 35mm motion picture cameras. You could mount a high quality achromatic diopter right onto its bayonet mount to focus onto the ground glass (I don't know, could you?). With the added sensitivity of a proline camera, you could better afford the two-stop light loss. And you wouldn't waste any optical properties going through an attached zoom, since pro cameras have interchangeable lenses. Cinemek? Redrock? You listening?
