Flash Triggers for 645D

I am wondering what options there are for firing off-camera flash using a pentax 645D. At the moment I have a Canon 5DII and use Elinchrom studio lights, which are triggered by the elinchrom SKYPORT wireless triggers. My understanding is that the hot shoe on a pentax 645D is different from the Canon, and therefore the Skyport triggers will not work. Is this correct, and if so, how do Pentax 645D users trigger studio flash wirelessly?
Thanks for any help.

Yes some of the contacts are different but not the main tirgger in the middle so you can use the skyport.

Cactus V5s here, used them on my older DSLRs and they're still kicking and doing the job just fine on my 645D.

Skyports are "dumb" (not-TTL triggers). All they care about is the center firing pin.
They'll work fine. The 645D uses the same hotshoe as my K20D and I've used Skyports w/ my K20D w/o problems.

Now if you have a Sony/Minolta camera...they were crazy enough to move the center pin so you need a custom hotshoe adapter to move it back so you can use normal triggers

Thanks - I must have been using it incorrectly the first time - my triggers work just fine as suggested when properly seated in the hotshoe!
