Well here is a little something to get your heads around. I’m not sure on the physics or the tech behind this post but I do know the maximum published sync speed for non Speedlight flash kit is a measly 1/200th of a second with the Canon 5D and 5D mk2. Not any more! The techniques used in this post were hinted to me by Martin Hogeboom in a cafe in Amsterdam last week and I vowed to give it a go and see if the rumours are true. All the exif is intact so please learn from it as you wish.
My little box of tricks - What's in the Sto-Fen?
I drilled a small hole then used instant Araldite to secure a peanut optical slave into the lid of a Sto-Fen diffuser. I attached heavy duty Velcro to the side of the Sto-Fen and my Plus 2 transceiver. Then I made a lead - female PC to 3.2mm mono mini jack. I cut down an old PC extension lead rather than attach a fiddly PC connector.
Here is the kit all assembled on my 430 EX2 flash unit.
And another shot from the rear. The Stofen / PW set up simply pushes on the top of the flash without the need for anything else.
Here's the set up. Full blasing sun, clear deep blue sky, and my Broncolor Mobil A2R flash unit with it's bare faced flash head.
Here is the Bron set up. Full power 1200Ws unit triggered by a PW Plus 2 tranceiver.
Here are the settings on my 430 EX2 flash.
Well here is shot 1 using 1/8000th second at f/2.8 with ISO 100.
Here is the same shot with the flash switched off.
Here is an f/2.8 close up at 1/8000th. Remember we are in full sun and it is almost obliterated.
1/8000th at f/2.8 with flash.
And here is the shot above without the flash on.
Again here is a close up at 1/1000th at f/2.8. All the exif data is intact on these shots so please learn from them the info you need to further experiment.
And without flash.
Back onto 1/8000th second for good measure. Flash set to 3m distance barefaced with built in 60 degree reflector (equivelent to a Speedlight on 24mm setting)
As above but without flash.
A more regular setting might be 1/2000th at f/2.8 for a fashion shot. Here it is with flash.
And here it is again without flash.
Rewriting the rule books is fun at times. However these especially dull pictures are simply to illustrate a technical phenomena. You may be interested in these findings in order to freeze action or to use shallow depth of field in your flash lit portrait work. Whatever your need, be sure to feedback and ideally post links to your pictures that use high speed non Speedlight flash. This may work with Elinchrom heads and Skyport – Who knows.
