I recently acquired this camera and it came with the No 3 Rangefinder focusing screen. When shooting landscapes I seem to be out of focus. The closer I am to the subject the more noticeable it becomes. When viewing the subject, prior to the shot, it always seems to be sharpest when the bellows are wound all the way back. Is that typical? Two recent images are attached. The image of the lions, shot from 8 feet away, appears to be front focused on the stonework in front of and below the lions. OTOH the one of the movie theater, shot from across the street, appears to be in focus. I use the split prism whenever there are some straight edges that I can line up. When I owned an RB67 in the past I almost always found that the best focus was with the bellows right up against the camera body.
