Not interested, my old film camera's lack the quick focusing system of my current Nikon's. Would not want to lug around my old F4s.
And you wouldn't have the fun of being surprised when you realize (too late)
that AF focused on the wrong thing.
AF is terrible at reading the phtographer's mind. And doing focus-and-reframe thing
takes as long as focusing manually.
Also, every AF system is different, and they all rely extensively on secret firmware.
So when it does something unexpected, it's anybody's guess why or what to do
about. Most aren't even polite enough to warn you when conditions make the
AF sketchy.
The problem with your old film camera is that it isn't old enough. Range finders
were quick to focus, once you develop the knack. And older still: large format
cameras were capable of enormous depth-of-field (e.g. f/64 or even f/90).
I must say that when I shoot pinhole, I don't spend much (any) time focusing.
f/250 makes it superfluous. (Strictly speaking, pinholes don't converge rays,
so they don't have a focal length. But in a camera, they do have an angle-of-
view and a hyperfocal distance, and for any backfocus distance there is an
optimum pinhole size. Odd, isn't it?)
Much of the weight of your F4 is the battery. Again, it's not old enough.
I lug around an F2 Photomic sometimes--much more heavily built than
the F4, but lighter because the battery is tiny (it only runs the meter).
