Comments on: Chris OConnell Strobes Above His Camera’s Sync Speed

Why don’t you guys try setting you on camera strobe to HS and trigger your studio strobe with that rather than using the wireless or the cable? It goes then well beyond 1/500 :) What do you say to 1/8000?…

@Dan – no, Hypersync is basically a system which tells the strobe to fire earlier than normal allowing faster shutter speeds without the result of lost flash power across the exposure. (Or doubling flash power effectively with same output at a twice faster shutter). It does not pulse the lights like high-speed sync.

So is firing the strobe’s twice for the 1/500 sync (twice because only half would ever be exposed if the sync speed is 1/250…) for each frame?

That’s what I’m not sure about, as with HSS with the Hot-Shoe flashes they fire multiple times for so that each part of the sensor is exposed to the flash due to the shutter never being open fully… so are the Broncolor’s doing the same thing? Or is that something that the Pocket Wizards are able to do? basically turn any flash into a HSS flash by firing it multiple times depending on the shutter speed?

No it is not the first 1/500th sync with studio strobes. It may be “the First 1/500th Shutter Wireless Synced Flash Sequence (on a Monday)” With the miniTT1 you can advance the radio sync timing to enable higher sync speeds on most studio packs/strobes. It takes some experimentation to dial it in but you are basically advancing the strobe timing (via the PW software for the mini TT1/Flex TT5) ahead of where it would normally fire to do this.

@dan Guess so…if the duration is short enough you can sync at higher and higher shutter speeds.

I think what he’s probably meaning is that this is the first 1/500s sync with studio strobes (as opposed to speedlites)

I understand HSS but I’m not sure how he’s doing it with those “studio” strobes? Are the Broncolors capable of HSS?

Well hard to if say it’s “the First 1/500th Shutter Wireless Synced Flash Sequence”. The PW flex units can sync well above camera sync using Hypersync with various studio packs including Broncolor. You need to experiment to set the sync timing advance with their setup s/w. The mini-TT1 on camera and any PW on the pack. (although the TT5 on the pack would allow remote control of power for certain packs). I’ve done high speed sync it with Profoto and been a beta tester of the Nikon flex units just coming out to take my D3 above the 1/250th sync speeds with studio strobes. Common with the built in CLS and speedlights but great to now mix studio lights in.

I used the TT5 and Mini to sync two canon speedlites last month. I was able to get them to sync all the way to 1/8000. I was stunned, there was no rear curtain shadow. There seemed to be a slight darkening of the image when you exceeded 1/2000 which I believe was caused by the front curtain not being entirely open in time. Still, it was marginal — a decent trade to sync the 5D MkII up to 1/8000

I shoot with a 5Dmii and have use the Flex and Mini for about 6months now and luv em. High syncs and ETTL so I can change up my flash power from a huge distance away. Great investment for me and my business. Course the high snyc speeds for Canon shooters doesn’t seem like a huge secret now though…

@Lee – I know my D70 and F100 make a “clack – clink” sound, and the various Rebels / D5000 type bodies go more “buzz-whirr” like the servos in an RC plane. Have you had any good experiences with mirrorless/shutterless camers – ala Lumix G1/Olympus Pen? I’m curious how a Canon G11 would do for high-speed sync. (obviously you wouldn’t get 11fps!)
