Gosh, I really hate to hear about the difficulty big people have to suffer through like that and walking around bumping their head on everything, feet hanging off the bed, out from under the covers in winter, etc. I'm pretty short and have troubles of my own. I think I have an allergy to beans too 'cause if I eat any kind of beans, being so short, I'll walk around for two days blowin' dirt all up in my shoes.

The quote you replied to was interesting concerning large hands and mirrorless camera's.
My favorite camera's were the D500 and D850 with the battery grip attached. I do not have large hands but I am 6'3" and my hands are not small. I found reaching for my custom buttons easy on these extended rigs.
Enter the mirrorless Sony a9, I found that I had to have the battery grip attached to make it much easier to handle than the a9 without the battery grip attached.
It also balances better with the Sony 200-600 and 600 f4. Without the battery grip making the camera body larger these lenses would, for me, be much harder to use hand held.
So yes, for many males, and probably some females too, find the mirrorless camera's too small without the battery grip attached to help us with larger hands operate our camera's.
Good luck and keep on shooting until the end.

Thank you for the kind reply. Your Pic looks great for your age and I'm sorry to read of the difficulties you're facing. I'm a (young I hope) 58, but facing some medical issues myself, (another surgery on Tuesday), but you know what they say, "laughter is the best medicine", so keep your chin up, stay well and keep shooting my friend! (and I really hope the flip flops work, just stay away from ladies in short skirts, and please don't let anyone talk you into those strappy sandles with knee high white socks! Not a good look at any age).
