Pentax Flash Unit AF400FTZ and the K-x

Can Pentax's AF400FTZ flash unit be used on the K-x? I note that then AF400FTZ needs TTL, which the K-x features. Thanks in advance.

G'day Kev. Welcome to the forum.
This is a common misconception.
The 400 flash you mention is a TTL flash indeed, but not a P-TTL flash (which is a further advancement on basic TTL metering).

All the Pentax dSLRs after the *ist D and DS no longer support basic TTL metering, but rather only implement P-TTL flash exposure metering, which employs a pre-flash to calculate exposure required to light the scene. This differs fundamentally to basic TTL, and as such the modern cameras (including the K-x) require a P-TTL capable flash gun to be able to automatically meter the scene.

But.....

CAN an af400ftz be used on a K-x? If so, how would I set the controls?
I have an af280t plus an af240ft plus an af330ftz and an af400ftz. I have a Pentax zx-50 but am wanting to get the K-X and it would be great to know if these flashes can be used somehow.
Thanks guys!

Probably better to ask those questions in this area of the forum. It's where all the Pentax flash gurus hang out:
