I've tried all wireless modes. It all seems to be working as it should. Only Wireless HSS can not flash. Here is just the normal P-TTL mode with 1/180 sec. Available. Otherwise is the normal P-TTL mode, incl. P-TLL HSS available.
Furthermore, I have tried a lot using the flash and everything tasted or flashed possible. And I had no overexposure (my K-5 is set to -0.3 or -0.7) Even bounce flash works as it should. Although my Pentax 540 tends not to overexposure necessarily, but I can provoke a total Fehlblichtung - with the Metz I have not done it.
Yesterday I photographed a Christmas party and thereby made approximately 200 flash pictures with my new Pentax K5 II, all the pictures were just as I imagine it. Sauber lit and properly exposed.
The fact that the flash has the touch screen and all settings (except the key lock) to be made on this one has no problems to use the flash in the dark.
I would buy the flash according to the current state again, for the price a top device - Made in Germany
Why Metz does not succeed this time for a quick release I do not ...
