wireless flash compatibility

Hi, i'v seen canon users (on youtube..doing wireless) using nikon flashes and it made me wonder if i can use my canon flashes wireless (using a trigger/receiver) on my pentax?
Maybe if the flash was set to manual?
I only ask because i don't want to try it with out knowing if it can damage my new camera.
Sorry if this is a dumb question.
Thanks from Casey.

I use 580EX II on K-m w/o problem (A/M flash only of course). No idea how the wireless adaptor will behave though.

Hey, thanks for the reply..i went ahead and tried it and it only fires some times so it looks like i'll have to buy another flash.
Thanks for the help

Did you make sure that you were at most as fast as 1/180 with your shutter speed? Also, did you give the flash enough time to recharge?

Intermittent function sounds odd and a third-party flash generally works fine on a Pentax.

Hey, now i feel stupid as can get...i had the flash set to high speed sync (or what ever it is called) so i allowed my shutter speed to be higher....i wasn't thinking right...that, that would only work with a canon.
I just tried it again, and didn't go above 1/180, and it seemed to work fine.
Thanks so much
From Casey.

Pocket wizard?
There are cheaper options if you're just playing. Wireless flashguns are manufacturer specific but pocket wizards are pretty much universal.
Hope I'm not stating the obvious.

Hey, i am actually using "cactus" trigger/receivers, which i assume i have to use manual with....but i really don't mind this.
I mainly take portraits so i can take the time to change the flash power.
As for stating the obvious, i'm so new to this, not much is obvious to me.

Nothing wrong with manual. I enjoy Nikon CLS with my S5 Pro and SB-800. I use camera manual mode and let the flash gun do its wireless iTTL through the camera.
You have iTTL too except you are the i.

To the best of my knowledge they support Canikon only, i.e., no Pentax support.

With Cactus V5 one can keep one flash on camera and trigger others remotely.

i was using v4 with a trigger on the camera, and a receiver attached to my canon 430exII, i'm not sure i want to buy v5 because i only recently brought v4.

I meant that they'll fire off any hot shoe. I honestly didn't even know that they supported TTL at all.

Ah, OK. Note that any wireless trigger I know of will fire off any hot shoe (except Minolta/Sony hot shoes, of course).
