Originally posted by Not a Number Whether or not later models support "analog" TTL is unknown.
About the brand dedicated models, I don't know.
The SCA (multi brand) models work well with any old TTL
Just use a SCA372 adapter for bodies without the added serial communication, and a SCA3701 or SCA3702 for any AF model, including DSLRs. Of course, with the old flashes pTTL is not possible.
I don't have a manual of the latest SCA models.
Only if it would tell the flash is not compatible with 3-digit SCA adapters, pre-AF bodies would not be supported.
EDIT: Of course, the reverse is also true. If a flash doesn't support 4-digit SCA adapters, it will not work with bodies of the SF or any later series.
I don't know which was the first Metz flash supporting 4-digit Adapters, but any MZ series will, because MZ means motor zoom. And to get the information about focal length, the serial communication is needed.
