Hi, I was just playing around with my RB67 in particular. Perhaps I am used to my dSLR with the modern lenses and took it for granted. I've been checking the focus of my RB67 with a thin piece of ground glass at the back of the camera on the film plane and verify that my viewfinder is in sync. Long story short nothing wrong with my camera. 1. Are the film era lenses especially wide open not quite as sharp as modern lenses today with the aperture wide open? 2. Is it a tough ask to shoot 6x7 medium format at a rather close distance by extending the bellows out and shoot the aperture wide open and expect eg ..the eyes to be in focus and not the eye lashes ....? So maybe I've been expecting the camera to meet my expectations rather than adapting myself to the camera ..... Even with modern digital cameras they use live-view or teethered to a computer screen right .... Keen to hear your thoughts. Thanks.
