(Laughs). If a Pentaxian has done anything like this, I don't want to hear about it!

I like Michael Caine's quote about being in Jaws 4:


"I have never seen it, but by all accounts it is terrible. However, I have seen the house that it built, and it is terrific.”

Sure, but it's perfectly fine as fill, though, which would be the majority use of onboard flash in daylight.


Cranked down to -2 stops, it can also simply add catchlights to your bounced key light, otherwise our subjects can have those black shark eyes.:)





I have that same setup to draw on, PDL, amazingly cheap and effective.


For HSS/P-TTL off camera, I use an Acon radio trigger - again, cheap and effective.

When I bought it, I saw the manual had a cross next to 'Slave' in the flash capabilities table, but I now don't think that means it can't act as a P-TTL trigger ... for starters, it says it can do that Contrast-Control-Sync thing.

Just so you know, the K-S1 has the same manual popup flash option as the K-S2 and K-3, Mcgregni.

It is not adjusting your exposure!

In fact, it can't use P-TTL when you turn the lens ring off A because you just took away its ability to do the pre-flash wide open. Lacking the info it requires to calculate what's needed, it fires at full power putting the onus on the photographer to stop up or down to adjust.

Manuals from any brand don't give you that reasoning I just provided, supplementary materials, personal experience and the advice of others do, none of which it appears you want to listen to.

Good night! ☺

But, Colin, why did you think the popup flash was manual?

Where had you ever set it to fire at 1/8 power?

That is what we have told you in this thread, and as documented by Pentax.

We cannot do anything if you continue not to believe this.

The flash is in auto mode while the lens aperture is set to A.



But you do. If you set it to f4 with the camera dial or the lens ring, it's f4.



I will try one last time, Cee Cee and then give up ... use the A setting, the P-TTL preflash sets the strobes off early. You say there is no pre-flash but you are wrong.

Don't use the A setting, there's no pre-flash, it fires once at full power and sets off the strobes at the same time.

That part of it is because if not in the A position the on board flash is always firing at full power.

??

The camera is in manual mode, the flash is in P-TTL mode.

The K-30 has no manual control of its popup flash.

Listen to what these good people are trying to tell you! ☺

Tell your strobes to ignore the first flash if they have that function, or get yourself some cheap Cactus radio triggers.
