I use *ist DS with an old Metz 40MZ-3i and SCA 3702 and it works just fine:
- ISO is read from the body with any lens in Manual, Auto and TTL modes,
- aperture is read from the body when the body can set it - it means
with A, FA and FA (FA J) lenses,
- when the flash is in Manual or Auto mode you can use any camera ISO,
- when flash is in TTL mode your choice of ISO is limited to 200 and 400
(although you can set higher ISO and use flash compensation on the body).
Every flash mode - be it Manual, Auto or TTL - works fine with any lens
(apart from that with older lenses you have to supply aperture
information to flash). Actually, up to several days ago I didn't have
any lens newer than SMC A and I was using TTL with success with SMC M
lenses. Now when I play with Metz and FA 35/2 I find that in green Auto
Pict mode even the flash AF assist light works OK and goes on instead of
built-in flash.
In summary I would risk a statement that on *ist DS with Metz SCA 3702
module everything works OK with exception of P-TTL (of course) and
limited ISO range in TTL mode. I really don't know why Metz says the SCA
3702 is only for *ist D...
There are several things to remember though:
- TTL flash won't work on *ist DL as this camera does not have TTL flash
sensor,
- there are some differences as to TTL flash support between DS and DS2.
There is an interesting page on the subject of flash with Pentax *ist
DS: http://www.jr-worldwi.de/photo/index.html?ist_DS_internalflash.html

The AF360 has an auto mode, but you have to tell it the ISO and f-stop, which
change a lot as the day goes on. Does anyone (Metz?) make a flash system
where the flash uses its own auto sensor, but it reads the f-stop and ISO
from the camera body instead of requiring us to set it?
Has anyone tried the Metz modules for the *istD on a DS? Metz claims that the
DS version is still coming.
Another approach: Regular TTL ( no pre-flash ) is claimed to be ok at ISO 400.
Does it at least not blow the highlights too bad? Maybe we could dial in a
-0.5 exposure compensation since we're normalizing everything anyhow.
