I also have my old Pentax AF200S Dedicated Flash used on film

Specifications state that it will operate on any Hot Shoe Camera.
I have also read that I should be careful with the flash in case the
voltage is too high and may damage my DSLR.
I would appreciate any comments on my particular dilemma

If you check out the following website you will see that your Pentax
gun has
a trigger voltage of only 7.65 volts and can therefore do no harm to
your new camera.

But according to that website, Canon states their cameras are only
safe up to 6V. I definitely wouldn't chance it. Besides, unless
it's an independent Auto flash, it won't work properly anyway unless
it has a full manual mode. Personally though, I'd check the voltage
myself before even trying it.

Agreed. I have about 5 flashguns of varying makes and have checked them
all.
Only 2 fall within the IOS 10330 standard for trigger voltage (less than
24V). It does seem however that individual makes of camera can vary from
model to model in their tolerance to higher voltages, and the remarks on
the
website may only apply to the Canon G model(s).

I would assume that most or all of the later models from every major
manufacturer will be made to comply with ISO 10330. Therefore whilst his
camera manual may give the info, he might well spend some time on a 'phone
call to Canon if this info is not given in the manual.

My new(ish) Panasonic FZ30 has the compliance statement in the manual, and
I
am happy using a Jessops auto flashgun with this when the built-in flash
is
inadequate. This gun has a measured trigger voltage of 6.2v.

The poster is right to be cautious, to ruin a brand-new camera by blowing
it's circuitry would be a great shame.

Dennis.
