The most versatile film camera system I use, is Contax 645.
- The negative is small enough to give 16 shots on a roll, yet big enough to get great prints uo to A2 format
- There is autofocus that can speed up operation if needed, although it is not terribly fast, but you can easily focus with this huge VF ( I have installed Maxwell treated screen for extra brightness)
- There is mirror lock up, multiple exposures, motor drive, extra battery grip, great metering system, WLF or prism, interchangeable magazines on the fly, shutter that goes down to 1/4000, reasonably fast flash synchro
- you have some of the finest lenses in the 35mm/350mm range, including Planar 80/2 and APO Makro Planar 120/4
- you can adapt Hasselblad lenses and shoot with automatic aperture stop down ( although you have to measure light at full aperture) - this includes lenses like 50/2.8, 110/2, 150/2.8
- finally, there are digital backs available for this platform if needed
Main drawbacks: cost, weight, no longer in production
For an "Old Man's" camera I would really see myself using a Rollei TLR with a light tripod. It produces simply wonderful images, and it makes you interact with people easily. It is a work of art and it is completely mechanical. You don't need to fiddle for vertical/horizontal. You can compose each shot thoughtfully.
