I do not know if anyone stated this before, but here goes, you should
check the voltage of the flash as it may be too high for the digital
bodies.If it is you still use it remotely.....Joe
I managed to find the correct dedicated module for $18.99 shipped.
The cheapest otherwise was $40.00 + shipping. I had enough in my
PayPal account to get it, and since I don't have an external flash,
I figure it's a good idea to go ahead and get the module.
Here's what the product info on the module states:
PRO2708 PROMASTER FTA 5000 AF TTL FL MODULE/PENTAX PROMASTER 5000
Series FTA modules allow for TTL, fully automatic, and manual
operation* with auto focus SLR cameras. It also features an
infrared focusing assist lamp to help you get sharp crisp pictures
in low light. The FTA module works on ANY PROMASTER 5000 series
flash including the 5750DX and 5550DX digital flashes. *Features
are limited to those supported by your particular camera model.
Pentax AF - Code # 2708 Pentax AF1/SFX, SF1N, SF10/SF7, etc.
Anybody know of any reason why this shouldn't work on my K20D? I'm
having a hell of a time finding anything about the compatibility.

Hum, it seems I was incorrect, never having seen a Maxxum 7000, the
first alpha mount Minolta I handled was a 7000i which had the "new"
flash shoe as well as the new lens mount. Sorry about the incorrect
information.

Actually, after looking again, it does appear to be a standard hot
shoe. When I first looked at it before, it appeared that one of the
electronic contacts on the flash was off-set a little more than the
contacts on the camera hot shoe. But, after looking at it again, it
looks like they do line up after all.
As for the discharge voltage, that I don't know. The only
documentation that came with it is repair and service receipts for
the camera. I'll have to see if I can find it somewhere on the web.
Thanks for the heads-up!
According to this page:
http://www.botzilla.com/photo/strobeVolts.html
....the Promaster has a trigger voltage of 4-5 volts.
Based on this discussion, that's probably OK - but it's your camera :-)>

Thanks, Brian!
Yeah, that looks safely within the voltage range of the K20D. I guess
the issue at this point is getting the correct dedicated module for it.
I've found a little info on that and so far the cheapest I've been able
to find is $40.
Gonna have to do some cogitatin' on this.
