Okay... I bought the flash unit.
Call me stupid, but I read and don't quite understand the instructions for the wireless sync.
Or maybe I do need to upgrade my firmware?
Just an update:
I've emailed Sigma Singapore regarding EF-500 DG Super P-TTL.
Initially there is no compatibility problem. Everything works fine.
However when K10D was updated to 1.20 and wireless control from onboard flash was enabled, the flash was unable to support.
With a firmware update the wireless flash will work.
Then again, it doesn't explain users who have exposure problems with it.
Thanks bro. I'll likely get the Sigma EF500 DG Super for my gf K100D. K10D I'll still use the AF540FGZ
Sigma Flash + K100D = no wireless flash.
I would like to inform you that for Pentax K100D there is no wireless function at all therefore even if we were to do any upgrading of firmware there will still be no wireless mode. - Sigma Tech Support
:bsmilie: Now my turn to headache over Sigma EF 500 DG Super or AF360FGZ. I know I'd always said get the AF360FGZ, but K100D can't do wireless... So maybe Sigma EF 500 might be better:think:
if get the sigma flash/lens from OP can get support from local sigma service centre a not?
Cannot. Cause OP warranty card no stamp.
IIRC Sigma EF-500 DG Super works much after the K10D & Sigma flash firmware update
