TTL Flash Triggers

I am in the market for a TTL Wireless Flash trigger for my Pentax K-x/Sigma EF-610 DG Super Flash and the Yongnuo YN-622 or RF603 caught my eye. However, altho these are advertised for Nikon and Canon, there is no mention of Pentax compatablility. A search on the internet revealed inoformation that the Pentax hotshoe pin configuration is the same as that on the Nikon, therefore the Nikon version of these triggers should work with Pentax. Obviously I am loath to risk it on the strength of a simple mention with no actual evidence, so I was wondering if any member has experience with the Pentax/Yongnuo combination they could pass on. Thanks

I have a set of RF603's I kept from when I used a Nikon and can confirm that they work just fine with my K5 and Pentax flash guns.

If you go for them remember to buy an extra shutter release cable for a Canon (2.5mm jack) a Nikon set is supplied with the Nikon 8pin shutter release cable.

The Seculine Twinlink system is another one to look at although you will need a few more £'s

As far as I know there are no P-TTL enabled wireless triggers.

However, I use the Cactus v4 with Pentax bodies and flashguns - just that everything is fully manual. (Which is usually the best approach anyway!!)

Absolutely agree.

I also use V4's and both my flashes are fully manual... Lack if P-TTL I'D A non-issue.

Should have been a bit clearer, as Matt say's there are no P-TTL triggers that I know of, and just to be really clear the RF603's are dumb even for Nikon and Canon although they do wake up sleeping flashes.

Ah, also worth mentioning that not all radio triggers will sync the Pentax guns.
A friend of mine has some Chinese ones for his Canon that work fine, but not with Pentax! Has to sync at something stooopid like 1/10s to work

The Cactus triggers are cool though

Thanks for the info guys.. I've been in contact with Yongnuo and they don't produce P-TTL wireless triggers for Pentax and they didn't answer my query as to whether the Nikon ones would work. So it looks like I'll continue to use the triggers (PT-04NE) I've got and use the flash in manual..

I use Nikon fit triggers from Cotswold Photography - They're virtually identical to the Phottix II triggers.

I have been using FlashWave III triggers and they works perfectly. Again fully manual.

Based on several online reviews, I have just bought a set of Cactus V5. Ordered from Gadget Infinity on the 20th and arrived yesterday (25th). I ordered 2 twin packs at a total cost of $143.90 (£95.82).
I had a quick play with them last night and they are simple to set up and operate. They have a nice quality feel about them despite the price. I especially like the fact that each unit can act as a transmitter or receiver. This means if the transmitter fails you can always reassign one of the others in its place.

I used them with a K5iis, a FGZ540 and a FGZ 360. All on manual. I tried putting one flash in the hotel bathroom with the door almost shut and it still fired.

The only criticism is the tripod mounting points are too close to the hotshoe and foul the QR plate and the hotshoe 'lock ring' is fiddly to operate well.
