AF-540 users help me out!

Hi everyone,

Can you check on your flash, when its mounted on the camera, if you can cycle through all the modes (P-TTL, A, M and SB).

I know when the camera is set on 'M' it is possible to cycle through all the flash modes, but when I'm on Av, Tv, P etc all the flash does is go from PTTL to SB but I want to use the flash on Manual settings. Currently tested my flash on K-5 and K-30 and its still the same, though I was sure on my K10d that the camera can be set on any of those modes and the flash can be set on M.

Any ideas? Does yours work?

Your memory serves you incorrectly, I believe!

Tried my AF360 on my K-7 and K10d. Only get the manual settings when the camera's mode dial is on M.

Just checked my FGZ-540 on K-20. It's the same-only M-mode makes it possible to use all settings. As I go over to Av or Tv the flash automatically switches to P-TTL.

Hmm, that's annoying then

It would be really helpful if Pentax can enable manual flash settings in those modes (Av, Tv, P etc) because im finding P-TTL such a hit and miss on the K-5 atm. Especially doing events, just don't know when the flash will decide to fire at full power in front of someone's face because the metering is off...

Never noticed but yes its P-TTL only in P,Sv,Tv,Av & TAv
Manual and A mode on the AF540 is only in the camera modes X, M and Bulb.

Metz flashes let you set Manual flash in all camera modes.

Just tried my K200d, and all 4 flash modes work on all camera settings.

If you set 'A' on the flash prior to switching the K5 camera on then the flash will saty in A mode for Av Tv etc.

Down side is for some reason aperture and ISO is not read to the flash.? whereas withe the mets45 Digital it is.

So you have to set Aperture and ISO on the flash and ensure they match the camera.
