A New Bare Bulb Flash Arrives

My guess is that these are so new that very, very few if any have actually used them yet, to say nothing of using them with the CL-360.

But I've been keeping a close eye on the Pixel King Pro trigger, too. I hope someone chimes in at some point.

There is no Pixel King Pro for Nikon yet, but I have tried the Canon King Pro with the CL-180 and 360, and they work fine in HSS (H-Mode), just the same as the YN-622C.

The Cells II does provide about 3 tenths of a stop more light though.

I read the Pixel King for Nikon is released in August, at least in the States.

Elv, interesting point about the Cells II triggering for more light (you mean specifically in HSS mode?). Why would that be?

Rumour has it that the Nikon version is due next month. Rumour. Conjecture. Surmise. Wishful thinking, perhaps? Can't be too far away though, there are prototypes floating about on test.

Yes in HSS mode. It has to be due to the pre-syn timing in some way.

I have another timing adjustment device, so I should be able to see if there is possibly more to gain yet over the Cels II, I just haven't had a chance to experiment with that yet.


But also at 1/250th, you can get 1/3rd of a stop more light when using full power with the Cells II as well. Because the Cells II is faster than the CL-Tx, and the flash duration is somewhere around the same as the shutter speed there, so it has to sync up right on time to get all the light out of the flash tube while the shutters still open.

Thanks, yes they mentioned they are speeding up development of the Nikon version on their website. It sounds like they must be reasonably close.

Woh, 1/3 stop? That's significant. Is the King Pro Cells speed or CL-Tx speed?

Where did you get up to with this? Did you find some setting that are working reasonbly well?

Unfortunately once the troll starts there it doesn't make much sense anymore.
.

I got HSS working but had to go back to standard channels to have the just introduced setting up to -4000 in the latest firmware. I am not a big user of HSS and rather stay under 1/250s and use a polarization or ND filter.

HSS is not very efficient and when I go to full power I have a flash duration of 1/300s which is enough to go to 1/8000s. In which you loose also a lot of emitted light because it is just bouncing of the shutter which is only opened by a fraction and moving over the sensor plane.

Hahahaha I don't see it as trolling but more as talk that is not contributing to the topic. I think the message has been received and hope it will be on-topic in the future.

Thanks for the reply. And very much agreed. I'm extremely unlikely to band or velcro any of these pieces together. I'm looking for a cleaner solution if at all possible.

Is there not an accessory you can find that already has such a hole already or a that has the 1/4-20 built in so you don't have to retrofit like this?

The following images show an option for mounting the FlexTT5 to the SpeedPro Bracket. I just placed an order for this right-angle cable from a seller on steal-bay to replace the straight cable. It should make it less prone to accidental breakage.

BIC,
That looks good. BTW, if you want to get the tube deeper into the Bowens adapter it can be done by carefully fitting the head through the adapter before mounting it on the cold shoe. Once you've got the tightening knob past the vertical bracket the head can be moved well into the modifier.

Here is the post in this thread. Forgot that I'd posted it here. Thought it was in another thread.

Are the connections solid here? I have the flash with regular foot connected directly to the tt5 and moved around a lot during an esession the other day and no problems. I constantly check for tightness even with an sb900 attached.

I used your attachment method in the beginning, but always felt like the plastic foot on the FlexTT5 represented a weak point. I haven't had any issues with my setup, but I regularly check all the knobs for tightness. Better to be safe than sorry.

See THISpost. No special configuration was needed on the PW's. It's not exactly HSS, but it does allow the Cheetah's to be used at any shutter speed.

I am bit confused with what you are saying as your link is pointing to use of YN622 _C_ for Canon. I still would love if Nikkor316 could share how exactly he went after it as him and I are having identical setup.

Did you make any progress here? As David mentioned you can only use the PC sync port on the the YN-622C receiver to get the pre-sync signal required.

There's nothing to do really other than connect it up and put the CL-360 into H-mode. Even when its not is H-mode you should get similar results from the Hypersync.

Which camera body btw?
.

Thanks David and elv.

I was having trouble with the YN622C's that I have, where the center pin of the PC sync pin was pushing the socket of the YN622 inside.

Finally managed to plug it into one of the YN622C I had (only 1 of the 4 I have has a usable PC sync port now, gotta fix em soon) and the sync is working fine upto 1/8000.

Ok, outside HSS (H-mode) the Cells II, YN-622C and King Pro are all pretty fast triggers, its the CL-TX which is slow there. (The Cells II uses the CL-RX so that RX is not the problem).

With HSS (H-mode) on, and at higher shutter speeds, its the early pre-sync timing that matters. In that case only the Cells II is ahead so far. So YN-622C and King Pro are equally behind about 3/10ths.

But with a timing adjustment (like PocketWizard has) it may be possible to get even better results than the Cells II in H-mode.
