Re: Pentax Response to Flash Selection for DS...? Hmmm?

I think you'd have to be using some real ancient age stuff to run into the flash trigger voltage problem. Back in the day cameras used a physical metal contact switch inside the camera to fire the flash. They were pretty robust, but could get burnt. A high switching voltage flash could overcome a dirty switch for a longer time, but then a technician would have to open up the camera and clean or replace the contacts. Solid state switches started to replace these 30 years ago and I doubt any high switching voltage flashes have been produced for 25 years or more.

Pentax is pretty cool because the analog TTL flashes still work with the digital TTL cameras. Thus I can use my AF280 in TTL mode with my istD, but you don't want to go sticking Nikon or Canon TTL flashes on your IstD or DS, because it could be bad and Pentax has already warned you against doing it, and so has no warranty liability. However almost any non-TTL flash should be OK.

this posting. I'm still confused about the flash trigger voltage

Also, I didn't realize there were different 'hot shoes.' I thought
a hot shoe was a hot shoe!


"Thank you for contacting Pentax Imaging Co.

While we couldn't advise you regarding the compatibility of non
Pentax flashes with Pentax cameras, the problem generally occurs
when someone tries to use a flash designed for one of our
competitor's cameras on one of our cameras. The pin placement on
the hot shoe is generally not the same which causes the short
circuiting of electronics inside.

Older Pentax flashes should work on newer cameras depending on what
model they are. However, you may not have some features available
on newer flashes.

We hope this helps
