Flash triggers and P-TTL

Matt's guide is for P-TTL, which you can't do with your equipment.
If it's of any interest, I have both P-TTL and non-P-TTL flashguns, and prefer to use the latter. The only time I use P-TTL is in a dynamic situation (like a party) where I can't be sure that the light won't change as I move around. And then I'll only use one gun, mounted on the camera with a diffuser.
In a static situation, like a studio, manual flash is far better.

Yup! Page 24, under "AF540/AF360: A mode", and page 26 "M mode". There's a small reference to "Triggering dumb slaves" on page 25 too!Is this in your guide Matt? if so, I missed it!

It's not just P-TTL George Matt's guide is for P-TTL, which you can't do with your equipment.
There's A and M mode in there aplenty! It's entitled "MattMatic's Pentax dSLR Flash Guide" - not P-TTL guide
Definitely agree about the choice of when to use P-TTL and when to use Manual

Sorry. Must admit I haven't read it - just went by the title of the thread - which is "Digital SLR and P-TTL flash guide"!
Now that I know it's not just about P-TTL I shall buy a copy!

The only way you can do that is by putting the camera into "M" mode. Then you can press the mode button on the flash to get either A or M.

It's OK to use A mode with just one flash, but it won't give good results when used with other guns because it has no control over them.The only way you can do that is by putting the camera into "M" mode. Then you can press the mode button on the flash to get either A or M.

Indeed.It's OK to use A mode with just one flash, but it won't give good results when used with other guns because it has no control over them.
And, of course, for A mode flash to work properly the distance between the flash "eye" and subject has to be the same as between subject and camera.
So, M mode (as usual) fits the bill very nicely for studio stuff.
Comes down to one of my often quoted "Things should be as simple as possible, but not any simpler"! (See here.)
