p.1 #1 · High Speed Sync OCF


Are there any off camera flash High Speed Sync options other than speedlights via IR or the new Pocket Wizards. I'd love to be able to achieve HSS with something more powerful along the lines of an Elinchrom Quadra, Q-Flash or something with more umph than a speedlight but I'm thinking there are not any other options? Thanks!

The only "sync" involved with high speed sync is telling the flash to start pulsing rapidly before the camera shutter opens. Studio flash units are not designed to pulse which is the show stopper.

But if your objective is shooting at wide apertures outdoors a workaround is using ND on the lens to allow the lens to be opened wider than f/11. The downsides of that approach are the need for substantial flash power and decreased AF performance and viewfinder brightness.

...Q-Flash...?


The Qflash Trio has HSS capability. It's less powerful than the classic Qflash models (80ws for the Trio versus 200+ for the others), but it is an option.

Thanks Brian. I was actually trying to figure out if a Quantum Pilot on camera could transmit HSS info to an off camera T5D but it sounds like based on what you are saying that my only HSS option with Quantum is to have a Trio or Pilot on camera with another Trio off camera. Love Quantums just not sure of the Trio is worth it. Now if there is some way to achieve HSS with a T5D......that would make me a happy camper

Sorry, no singing Kumbaya around the fire pit today. The x5Ds are not HSS capable. Too bad, because they are more powerful than the Trio.

Still, a Pilot and one or more Trios looks like a good system in many respects. (But the Pilot is funny looking. The Pocket Wizard Mini TT1 is so sleek and techie, and the Pilot is soooo funky.)

there is a company in Hong Kong that is offering a TTL trigger for Nikon and Canon.
There has been some stuff on Flickr about it by an Aussi Strobist group.

Here is the link to their website. http://www.pixelhk.com/

The triggers are apparently available via one or more eBay resellers.

May be work some research.

What's wrong with the new PWs? I love mine.

The question isn't one of one trigger over another, it's of getting FP/HSS capability with something more powerful than a Speedlite.

that doesn't cost an arm, leg, or kidney?



I've been thinking about different ways to
achieve HSS disregarding strobe location.

practical, ridiculous, or not:

1) electronic shutter camera
-most flexible
-limited only by duration of strobe
-shorter duration strobes are always better
-commonly available dslrs are old with lower resolution


2) brand specific camera + brand specific hotshoe flash
-limited by power of hotshoe flash
-limited to brand specific hotshoe flash


3) focal plane shutter camera
-requires timing curtain opening & strobe firing
-with a strobe t0.5 equal to curtain speed one can only get 1/2 max power of strobe setting and ~1:1 light reduction from strobe thereafter.
-limited by speed of shutter curtains
-the slower the curtain speed of the shutter the longer duration strobe setting needed
-long duration strobes or flash bulbs give better, more even, results
-prone to reduced exposure/gradation from strobe in direction/tail of curtain travel
-faster shutter speeds than curtain speed = wasted power
-less efficient than #2 and requires experimentation

A) Canon:
-must use one of the following:
1) brand specific speedlite mounted on hotshoe capable of HSS + optical trigger
2) at least one PW flex/mini mounted on hotshoe? (maybe multimax?)
3) at least one radio popper mounted on hotshoe? (+brand specific hotshoe flash)?

B) Nikon
-must use any nikon auto FP capable flash mounted on camera hotshoe & use speedlight pc sync port (or camera pc sync port?)


4) Leaf shuttered lens
-dependent upon speed of leaf shutter in the lens
-MF or larger systems
-typically limited to 1/500
-may be possible to use canon 35mm body because it can mount wide array of lenses through adapters, but one pays a penalty with no AF, possibly no ttl metering, and must always use mirror lockup. could be a ridiculous hassle to time ML, focal plane shutter, and leaf shutter for exposure.


5) Mirrors
-When outdoors with/without strobes this could be an option under some conditions

That's what I do with my D50 . I've achieved 1/800th sec at 100 m with the RF602's blog-link and the other day I did some tests and came up with 1/4000th sec wireless flash using an optical trigger . D50 at 1/4000th wireless .
With the basic on-camera flash you can fool the camera into not knowing there is a flash attached and do what I call realsynch flash at any speed .
realsynch flash
With the D50 and an old SB24 I'm getting 6 X the power of a D90 and SB800 .
