Your exposure mode preference for P-TTL flash?

Thanks for the clarification. Another undocumented feature, I guess. Does this bias apply to the EV scale as well? My comment was specifically suggesting EV scale as a preferred option over the green button.


Edit: I just tried this on my K-3 and can confirm the change in green button behavior in regards to whether a P-TTL flash is detected. The same is true in P, Sv and Av modes without the green button. The camera maintains a separate program line for flash, but I guess it never occurred to me that it would extend to the green button.

No problem. New features come out all the time and it is hard to keep up with them.

Why are you turning the flash off/on in M mode? Metering and operation in that mode should work the same regardless of whether flash is mounted, with the exception that the shutter speed is capped a 1/180s. Use the EV scale to meter the exposure. Green button metering is unnecessary unless you are using the aperture ring on vintage lenses.* P-TTL flash contribution is independent of the shutter/aperture settings in M mode.

* Even when using modern lenses, it might be good to consider changing the settings option for green button in M mode. Default is to the program line.

I only have the English version of the K-70 manual and have been unable to find anything about a flash "off" feature. Can you provide the language and page so we can see what you are referring to?

What he said ^^^

One of the beauties of P-TTL flash photography is that it sort of frees you to use the aperture and shutter speeds appropriate for the ambient lighting and subject.

As for candids...my experience has been that it is only the first flash photo that is candid. As soon as you do it, you have blown your cover.

How much attention do you want to give to the process? For the cases you describe, priority should be given to shutter speed to avoid ghosting and aperture for adequate DOF. The highest level of control is available in M mode. I would avoid Auto, unless you are willing to let the camera get "creative" on what it thinks you need. I would avoid auto-ISO for the same reason.
