I guess your flash doesn't have a handy dandy built in calculator.

If it doesn't you can always create your own.

They're quite simple to use:
1. Set shutter speed to x.
2. Focus.
3. Read distance.
4. Cross reference distance to f stop and ISO.
5. Set f stop.


Which seems like a lot of steps but once you get used to it they happen very fast.

The exposure doesn't have to be perfect, only within 1/2 stop or so.

How much harder is a nondedicated, non-TTL flash to use than a dedicated TTL
flash? I'm looking at the flash instructions for my Ricoh XR-2s (Sears KS
Auto), and it looks like a lot of work. I can't use aperture priority
exposure; rather, I must select a shutter speed, divide the distance into
the guide number, and use the quotient as my aperture--only if my flash is
on "full" (I assume).

If I change my subject distance, I must change the aperture.

Sounds like a lot of work!

Which attribute would go further to simplify the routine: a flash that's
dedicated but not TTL? Or TTL vs. merely dedicated?

Does anyone here still use a nondedicated flash? If so, why?
