Sorry to hear you suffer too Barbara. At one point I gave up m4/3 because I was struggling with my neck, and went to a Sony bridge. Although I didn’t have to change lenses, it was still heavy on my neck until I discovered a harness that solved those issues.I agree as a fellow sufferer. I sold my Nikon D7000 for the same reason. I now use a Panasonic GX7, GX80, GM5 (my hiking camera) and an Olympus Em10 Mk 2 (nice big dials when my hands are really bad). M4/3 brings back the enjoyment of photography. Incidentally I don't see why you should have upset anyone - It was a very valid point.
Earlier this year I saw the G80, and tried it on my harness with a100-300mm, and realised that I could manage both the weight, and with the new camera bag I’d bought could also manage to change lenses, albeit slowly and clumsily, so went for it! I still have the bridge camera for those days when changing lenses would be a disaster, but I am enjoying being back with m4/3.
I thought I may have upset people moaning about my RA, and that perhaps I’d not explained myself properly!
