Missy,
Sorry to hear of your hands. Dealing with advancing age is an issue for all of us (38 years on Hass 500cm). I agree that
my 500cm, 40mm, and P1 P25v is a bit of a handful.
That said, one option is an SWC/903. The 38 Biogon is reputed to be a better lens, but the 40 Distagon offers reflex
viewing. I know several friends who use their SWC's hand held as a candid street camera with zone focus. It's less
precise than a V with a 40, which might be an issue with your CFV39. But it allows you to keep your V system gear.
Others have offered options are good as well. Eventually, only you can answer your situation. But don't give up.
