K10 -underexposes with TTL
I believe that the Jessops flash doesn't support P-TTL and I know for sure that the K10D doesn't support TTL only P-TTL.
About the P-TTL and Pentax it seems that the only camera that expose correctly is the K-7 all others have around 1 stop underexposure with P-TTL. The solution around this is to set the flash output in the camera +1 EV.
As for P-TTL vs TTL -the TTL is what the gun reports on its lcd screen but as far I I understood the Jessops gun is menat to eb suitable for the K10D (or have I been mis-informed by the store?)

I have no personal experience of the Jessops flash but as far as I know, none of them is P-TTL capable, they are TTL flashes.
The only Pentax DSLR's that are TTL (and P-TTL) enabled are the *istD and *istDS.
None of the newer Pentax DSLR's (including the K10D and K20D) supports TTL flash metering, only P-TTL.
If you were told by the store that a TTL only flash would be fully compatible with a K10D, you were misinformed. All third party Pentax dedicated flashes can of course be used in manual mode, including Jessops products.
They were told it was for the K10D....mmmm
These days I use SRS as a supplier -I wish I had known of them before!
Thanks guys for your honest comments. This forum is a great place!

If I use a AF-540 as a wireless slave to my K10d with the built-in flash
set as controller, I suppose the compensation will affect the remote flash gun.
But what if I set the built-in flash as master, would that compensation affect both or just the built-in (or just the remote) ?
Thanks

As I was brought up on manual flash I guess I'll cope! Its frustrating that the Jessops guys couldnt have told me that the K10D they'd sold me wouldnt work in auto mode with the gun I later went in to buy from them.
They probably hadn't a clue. How old was the shop assistant who served you? 17? 18 maybe?
Nuff said.
