yongnuo and pentax - HSS and TTL

Hi volks


Does anyone tried to use HSS on Pentax,

specifically one of the YONGNUO HSS flashes?


I'm a little bit confused about Canon, and Nikon versions - because there is nowhere nothing about Pentax - at least for HSS - or maybe I was blind in the Google


--
I almost ordered 585 EX - but from what I've read here, it doesn't have HSS ?? -


Which Yongnuo should I order to have HSS anf TTL on my Pentax ?

--
And what about the remote trigger for it ?


Is it does HSS work attached on the camera , or it must be triggered by remote attached in the hot shou ?


Or is it irrelevant - and can be do both way ?

--
What triiger remote from Yongnuo is suitable for this, because I have see several of them. ?


--

Thanks everybody !

Yes, I've used it. HSS for Pentax is a flash function under P-TTL and requires either a physical connection from a P-TTL device (TX or flash) to the camera or a P-TTL slave relationship to a P-TTL master having such a connection.

Yongnuo does not support HSS for Pentax in any of their models.

That is correct.

They don't make an HSS flash for Pentax.


Sorry!

They were supposedly planning on updating for HSS functionality in a later firmware update but I have not heard about it happening. Plus I have not attempted to update the firmware on my (2) 585EX's.

They are still a great value proposition though!

As far as I know, Shanny SN600FGZ supports HSS.

I'm currently looking for your suggestions - and I also now realised ,


that I'm not familiar with HSS settings into the camera.


--
I have KP which maybe doesn't support HSS at all ,

and
K3 - which does have dedicated wheel position "X" - for flash sync speed, but I don't know how to use it either

Your K-3 definitely supports HSS, just not for the on-board flash. The KP will also work with an HSS flash as will most* (all?) Pentax dSLRs. The key is that the HSS magic resides in the flash with very little work done by the camera. There are no required on-camera settings for external flash HSS; just shoot and be happy. HSS under Pentax P-TTL works something like this:
  • The user configures a supporting P-TTL flash** for HSS mode
  • The camera detects both HSS mode and the flash and allows the full range of shutter speeds
  • On shutter press, there is the usual pre-flash with the camera sending flash the meter reading and, presumably, the curtain slit travel duration (dwell)
  • The actual sync signal is sent via the hot shoe data pin. The main sync contact does not fire unless shutter speed is at X-sync or below.
  • The flash fires a modulated sequence of short bursts during the shutter action
Not all P-TTL flash (Pentax-brand included) support HSS despite claims of "full" P-TTL support. I hope this helps.

* The user manual for Pentax dSLRs usually provides a feature matrix for external flash that includes a row for HSS support.

** Some RF TX/RX systems are also capable of P-TTL with HSS emulation. At present, Yonguo does offer such.

on board is what ? Flash mounted on the camera ?

--
So, how zhat works then ?
--
I'm glad you pointed it out . I'm investigate Godox right now. 600TT - and how I can use one.


It says it's multibrand on many places. On some says Canon, Nikon or etc.

I think the flash is the same,

but the radio trigger is - Nikon, or canon, or some other brand.
--
They're gaving the first letters of the brand, in the name of the godox radio triggers.

-
S is for Sony, N, for Nikon, and P for Pentax..

I don't know which of these is suitable for Pentax.

On-board means the flash built into the camera. External is a flash that is not part of the camera.

The Xpro-P is the one you want. It has full TTL and HSS capability with all Godox speedlights and strobes minus the AD360II.
