Frame rate drop to 3 on K-5 with Flash!!!

Yesterday I joined a wedding photographer who works with NIKON D300 with SB-800 or SB-900 (I did not notice that). I worked with K-5 (of course) and METZ 58 AF1.

One significant thing I noticed is that the frame rate per second of the D300 with FLASH remains very high on my K-5 it dropped to about 3 frames per second .

I worked with 6MP JPEG, Flash was on reduced power - 2 / 3, shutter speed was 1 / 60 to 1 / 100
I tried to reduce the power of Flash to a minimum but still did not change anything ... Still 3 Frame per second .

With flash "OFF' K-5 fired at an incredible pace and beautifully, without that I changed anything except turning the flash "OFF" .

Has anyone managed to get 7 frames per second with flash is working on a K-5?

Was your flash set to p-ttl? If so, that makes the camera spend time on preflashes inbetween exposures. Try switching the flash from p-ttl to auto or manual and see if that makes a difference.

That aperture-ISO combination seems to be quite demanding on the flash, perhaps the delay is from the flash recharge rather than from the camera? Try shooting at a higher ISO and/or larger aperture and see if it speeds things up?

I noticed that too, it was already with K-7 so the case. It actually is 2.9 fps and that is excatly the same as with K10D, so there is some limitation within the electronic system. If you use something like Cactus then you can maintain 7 fps with off camera flash.

No idea how it is with Pentax flash, but with firmware 1.01 it didn't worked different.

In the Custom menu is a line item that allows the camera to release the flash before fully charged - would that help?

Looks like it's a limitation.

I've also confirmed it with a Sigma EF-500 Super.
Regardless of drive mode, release during charge or WB in flash settings, the max rate for shooting with flash is 3fps.

Just tried this out for myself on the K-5 and it defaults to 3fps even if the flash is off but on the shoe. Can anyone test to see if this also happens if the PC socket is used? If so this is extremely disappointing for me. I was going to invest in a nice set of mono lights but if I am limited to 3fps shooting with flash then I will not bother.

as I said with cactus it works. I have no cable at home to sync, but it did work before after firmware 1.02

Yes, it seems to also drop to 3fps when something is mounted on the hotshoe, regardless of it being powered on or not.
