All the popular radio TTL flash triggers, like PocketWizard or RadioPopper, seem to be only available in Nikon and Canon flavors. Are there any models capable of transmitting Pentax P-TTL data?

But, I don't know technical detail, however a new complet solution is to do it with posibility of managing by computer / laptop / tablet / smarthphone, it mean to do it by direction to future ... –  user11163 Aug 16 '12 at 10:22
    
@KarelFiedler what do you mean by "transfer"? Do you have any references about a computer/etc controlled solution? –  Imre Aug 16 '12 at 15:23

This radio trigger appears to support P-TTL and high-speed sync.

I found this in this dpreview forum thread: http://forums.dpreview.com/forums/readflat.asp?forum=1036&message=40799541&changemode=1

New product! Cool! –  mattdm Mar 7 '12 at 17:29
    
I'd be happy to accept this answer, but the product is still "available soon". Oh well, let's wait some more... –  Imre Apr 23 '12 at 20:05

I have a sample and will test it out this weekend. –  mattdm Aug 16 '12 at 11:41
    
A review reveals it's a clever solution converting optical commands into radio signal and then back to optical. –  Imre Sep 6 '12 at 6:37

So, having looked for some for a while, I'm going to have to sadly put forth "No" as the answer here. The TTL features of the radio triggers are relatively new, and their makers have (reasonably enough from a business point of view) gone with the market dominators first.

Hopefully, they keep hearing enough from Pentax users that they'll consider the smaller niche worth investing in eventually.

Personally, I keep holding out hope that Pentax (and now Ricoh) will simply include radio triggering as a basic feature built into an update of their flash system — but that's pretty much just a fantasy at this point.

I, sadly, have to agree with @mattdm - Not a hint of P-TTL option on radio triggers and I've hunted hard for them. I ended settling with Cactus v4 (which have actually worked well) and since I've been using Alien Bees, which are manual anyways, it stopped being an issue. –  John Cavan Oct 6 '11 at 1:50
