Which Flash for my K7 ?

I'm going to upgrade my flashes for my Pentax K-7 and K-20 . At the present I have a Sigma 530 DG Super and It works quite fine. Any suggestion for a fine P-TTL flash suitable for digitals ?

The Sigma you have works fine on digital. You'd be changing just for the sake of changing. If I was you, I'd put the money for a second flash (preferably the same thing, so the interface is the same), or, if you don't use flash much, toward an extra lens.

I'm not completely satisfied with my Sigma especially when I use it in TTL-mode to fill-in some shadows.
It works perfectly in manual mode instead.

Thanks Fletcher

I will test it as soon as possible.

I bought one of these recently and am well pleased with the performance - and price!

And another vote for the Metz 50. P-TTL has been excellent so far.
