I was wondeing if the Pentax AF-200FG electronic flsh unit would be compatible to use with a Pentax ME film SLR camera.
I'm not sure if the ME supports the P-TTL and TTL designation on the flash. The ME manual does not mention these designations.

I get different answers at different stores. I tried the clip on boot at the store and it fits. I don't want to buy it if it will not work.

I don't believe the flash supports regular auto mode, only manual, TTL, and P-TTL. So on your ME, you would need to use it entirely manually, would could be a pain if you don't have aperture value tables for it

Thanks for the reply Adam.

I'm still not sure what the flash specification means by TTL or P-TTL. The flash states it has TTL (auto), P-TTL (auto) and Full (manual)

The only TTL I know is transistor-transistor-logic but it may mean through-the-lens. I looked up the specs on the Asahi Pentax ME and it does have through the lens metering. Do you think this is what they mean?

TTL (indeed Through The Lens) flash requires a special TTL flash sensor. The ME doesn't have one, as they weren't introduced until the A-lens era. Our camera DB confirms this:
Pentax ME - Manual Focus Film SLRs - Pentax Camera Database and Reviews

I believe the first Pentax SLR to support TTL flash was the Super A: Pentax Super A/Super Program - Manual Focus Film SLRs - Pentax Camera Database and Reviews (the last one being the *ist DS2)

The TTL sensor is typically located behind the mirror and is mounted in the left wall.
