Yet another option for MF is the Mamiya 7II. Weighs less and is smaller than your F5 but has the advantage of 6x7 negative, silent operation, no flash sync limitations. Beautiful piece for street portraits & landscapes. Panorama (24x56mm) if you want to spend another bunch of money. Downside is limited selection of lenses & like any MF camera you just can't get 5 frames a second out of 'em.
