...or do something similar to the Phase One backs.
Super high resolution for "normal" ISO range, and use clever "bucketing" of the photosites to increase the ISO & quality while sacrificing pixels.
(Though their method of using diagonally arranged G pixels is obviously patented)

Who knows...

The older Metz 50MZ5 with SCA3702 also 'tracks' the ISO and aperture of the camera.

Obviously the communication between camera and flash is always there, but Pentax flash guns do a 'one take' reading of the values - so if you change the body then you have to adjust the flash.

With the 50MZ5 you can leave the camera in Av or M and the flash tracks automatically. However, once you override the aperture on the flash then the 'linkage' is separated and the two behave like the Pentax flash. Switching the SCA mode to M and back to A will restore the link

That said, P-TTL & HS is actually useful for fill in. However, certainly you get more reliable results using "A" or "M" on the flash

Most optical triggers use an SCR device, as far as I know.
There's always the possibility that it could fry the optical slave - but that's much, much cheaper than frying a body

There is also the Wein Safe Syncs that allow coupling for very high trigger voltages... but that'll probably be more than you want to pay.

Personally, I'd try the optical one and risk frying it (though I'd say 75% chance it'll work fine).

Sorry can't help much more!

There is an excellent guide on TheLightsRightStudio.com

Congrats

Personally, I'd say there's nothing as good as Silkypix for image quality and features.
For usability, some may find Lightroom, Aperture, or Capture One easier. Silkypix is perhaps a little "quirky", but it doesn't take much to get the hang of the GUI... if you can read the manual and try a little Googling (I have put some quick guides to Silkypix and Capture One on this very forum )

I've tried them all, and Silkypix still ranks as number one for IQ

Matt

Looks interesting Thanks!
Matt

Wow! That's a cool addition if they've done that! And it's not in the manual.
Probably like you, I'm waiting for the K7 pricing to come down a touch (and I'll have to trade in a few lenses and things!)

Matt

Just to add to this thread:
I downloaded and tried DxO Optics Pro 6 as this promised better noise control.
Yuck! I took a fairly high ISO image from the K20D and it looked like utter mush - all smeary and horrible. Compared it with Silkypix Developer Studio Pro and that brought out so much more detail while still reducing the noise. The difference was unbelievable!

Saved me £70 as well

Sorry for going off topic... but how? Read through the manual and the K7 flash interface appears to be the same as the K20D.

Besides the title thread mentions "X-sync" problems.

NOTE: The K7 manual has some information about the X-sync socket:
1) High trigger voltages could cause an issue (though no mention of how high!)
2) If the flash's PC connector uses reverse voltage (i.e. centre pin is negative) there could be an issue for camera or flash.
