Had a heart attack 3 years ago and it took me two years to get back on my feet and stop worrying about when I was going to die.
Five years ago I sold my Mamiya RB 67 and lens because I could no longer hand hold it because of Arthritis; should have traded it for an RB 67 pros S, anyway big mistake.
I now shoot 5 x 7 and have a Toyo 4x5 View that I refuse to give up because I might need it someday.
I also shoot with a Canon Digital when doing wildlife.
Your options are these: Go live everyday to it's fulliest or just give up.
The only cameras i sell now are those that I have restored.
