Yongnuo mastering P-TTL and HSS: new YN585EX model

They say:
Itís TIME for P-TTL!

I guess it is the first P-TTL flash option from Yongnuo.

The YN560 also works with Pentax p-TTL but I don't think it has an option for HSS.

I've read it a few times but I don't see any mention of HSS. But any P-TTL is a step in the right direction anyway.

no p-ttl with YN560

Scratch this. I pulled my YN 560 out and though it is fully compatible with Pentax digital cameras, it is entirely manual so there is no support for automatic p-ttl flash.

Its great to see another option in the budget category for a dedicated system flash ..... maybe the K1 is finally making some third party companies sit up and take notice ?

I can see that this flash is designed to work with the Pentax Optical Wireless system, but is it fair to presume that as a Yongnuo it would also work with Yongnuo triggers as part of a multi-flash group manual setup? Also I wonder if it includes a radio transceiver built in for this purpose as well ? A such it would surely be a really versatile unit.

Sawitar, have you used Nikon before ? 'Commander' is the terminology used by Nikon I believe for what Pentax call 'Master / Control' flash, for the on-camera triggering purpose. I only like to emphasise a distinction because the 'commander' mode on Nikon, including their dedicated wireless trigger devices, implies a few extra features with multi-flash control, ratios and groups, that the Pentax system does not have.

Continuing my pedantry with terms, the spec list above includes 'FEC, FEB' .... this I interpret to mean 'Flash Exposure Compensation' & 'Flash Exposure Bracketing' .... on Pentax the term is 'Flash Compensation', and I don't think we have flash bracketing ? If so I'd have thought it would need support through the cameras ?

This is what I wrote in the other thread on the YN585 (maybe they should be merged?)

Probably not, since they don't list radio triggering among the features. YongNuo has a history of parallel incompatible systems, even among their radio triggers. The 565 and 568 canikon flashes cannot be controlled by the 560TX. The new-ish YN685 does support TTL (e or i, depending on version), 603/560 radio, and 622 radio protocols. Still, seeing a P-TTL flash from YongNuo is encouraging.

Looking at the feature list for all the other flashes on YN's website, if the YN585 had a radio receiver, it would say so, near the top. Looks like it is optical P-TTL only. Maybe there will be a "for Pentax" version of the YN685 eventually...

I hadn't seen that on the other thread, sorry. I'm not a Yongnuo user, but I've read comments and heard the frustrations about those sorts of inconsistencies through their range. I think that a Pentax optical wireless flash alone is less attractive than one with built-in radio control as well. Obviously I presume this new flash will work also as a basic manual flash with triggers in manual mode, although the main point of it is likely to be the P-TTL support and functions. HSS will be quite important for this to be very popular I feel.

What, seriously? So if I want P-TTL and HSS, I need this one, but if I want one that works off camera I need a 560 series one. I can't have both?!

I'm not saying that specifically .... It was pointed out earlier in the thread that HSS was not specifically mentioned in the spec listing at the start . It does say 'full TTL support', which I guess could be interpreted different ways .....


looks like we have to wait for more detailed information from Yobgnuo.

I agree - "either-or" would be more attractive. It looks like YN is making some efforts to integrate their various lines. Since the price difference isn't that great between the 685 and the 565 or 586, it's a little surprising that they didn't go the "either-or" direction from the start for P-TTL. Maybe the 585 design has been on the shelf for a while.

It will be interesting to see what the new model number means. There is no 585 for any other brand, which is surprising.
