And a little note: auto iso is the mother of all evil when it comes to flash.
I love Tav mode in K30. I am think of using of a uper limit for Auto iso (Min 100 and Max 125)

You can use just as well M mode and iso 100 or 125 The issue is that iso directly affects the gn of the flash; which affects both minimum and maximum distance. So you have to actively keep an eye on it and possibly adjust on the fly; and that is far more complicated with auto iso.

Yep...what he said.

IMHO, auto-iso is a clear and present evil. It creates many "corner cases" where camera behavior does not meet the norms of logic. I can think of a few situations where it is very useful, but most of the time, it deserves to be turned OFF!

My problem is that I couldn't figure out the flash range I always have to try and try to get a good result. Still miss my former AF-280T which is quite limit, but it is very easy to calculate the flash range because there is a color table on the back :P

Btw, anyone tries this flash on a film camera. Mine is P30.

I tried the EF-610 DG Super on my Super Program (TTL flash), but the Sigma did not register as a dedicated flash. Yep, full power with no flash-ready confirm in viewfinder and definitely no TTL. I was truly disappointed since Sigma claimed at the time I bought it that it was backward compatible with earlier Pentax TTL bodies.

No problem though, a AF-280T is on its way to me from KEH.

I have the same problem with P30 and the Sigma. Too bad. There is a manual flash mode (sync at /100) but there are many calculations.
