K-3 Master and Controller flash switched

willskywalker93 · 02-09-2015, 11:02 AM

I was playing around with some beginner flash stuff last night with my AF360 and k3 and noticed that my master and controller flash options seem to be reversed. When I would set the pop up flash to master mode +1 EV, it did not contribute to the exposure. However, when I set it o controller mode, the pop up flash contributed to the exposure. I don't have my K3 on me right now, but would a simple resyncing of the flash fix this issue? Is this common?

Thanks!

I'll test this later. I have noticed the on board controller flash contributing to exposure (and causing reflections and shadows with larger lenses) in wireless controller mode and have been frustrated as to why......

I understand that the controller will contribute to the exposure to a degree anyway, but I was surprised that it seemed to contribute more in controller than in master mode.

I have encountered the same issue on my K3. Downgrading firmware to v1.11 does not help.

Is there any chance you have your off-camera flash set up for contrast control?

No. It is in leading curtain sync. Also I have a KX which actually works properly with the same af540fgz flash.

I not have experienced this issue, though I can imagine a few scenarios where it might occur. I don't own the AF540FGZ and cannot test directly against that flash. I can attest that with my Sigma EF-610 DG Super and the K-3 the controller contribution is minimal.

You might want to contact Ricoh/Pentax support to see if they have any advice.

It is important to note that camera/subject distances play a critical role in this, this is the reason why using an external flash for a controller is better as it is possible to maneuver flash head away from close subjects while still allowing for wireless optical triggering.

Close subject is one of the scenarios. There are others of course. IIRC, there are options that involve actively shielding the subject from the controller while bouncing the signal to the slave.
