Good luck to you Don and Lou With your health issues and your gear choices. Having just turned 76 I can relate to age-related issues.
I still have my M9, now with a Kolari sensor, and many, many Leica lenses. However, age-related poor eye sight keeps me from using it the way I used to. Now using my WATE 16-18-21/4 or CV 15/4.5 set to f/9 and infinity on the M9 has to suffice.
My primary camera these days has been my Sony A1. With appropriate adapters I can also use my Leica lenses of M and R type on the A1, some even with auto focus. However, I rarely do that as Sony now has an excellent set of native FE AF lenses.
I also still have Nikon, Olympus, and Fuji GFX gear, although I gave some Nikon, Olympus, and Sony gear to my kids. Next to my Sony A1 and A9 cameras my Fuji GFX 50S and its spectacular lenses sees some usage, but not enough. The Sony A1 camera, although 3 years old, is still technologically pretty advanced so that Nikon and Canon are still catching up.
I am looking forward to a future Sony A1 Mark II camera, provided it makes another jump forward technologically. Similarly as the Sony A9 Mark III did, but with at least 50 MPix.
