A while back I decided to ditch the Canon ST-E2 wireless trigger for a number of reasons – those being:

1. It relied on line-of-sight
2. It didn’t have a very good range
3. It wouldn’t work with non-Canon gear

I, like many others, have been salivating over the new developments in radio trigger technology.  And, at my last job, I had access to multiple lights, strobes, and such for experimentation.  So, in order to do said experimentation, I decided to invest in some Cactus Triggers that I purchased off an online web vendor (I forget the vendor off the top of my head – search the archives and I am sure it’s there…).  Much to my chagrin though, it would not work with my Canon 550EX flash.  So, when I left my previous job, it was back to the ST-E2.  In order to spur some motivation to invest in some more serious lighting gear on my own, I decided to sell the ST-E2 to fund the purchase of some Cyber Syncs.

Long story short, I ended up with no off-camera method to trigger my one flash unit.  So, I was back on-camera.  Needless to say, ambient light photography was a large focus for that time period.  Well, after the economy stabilized a little for the household with my state job, I decided to invest in the Cyber Syncs – but as a measure of insurance, wanted to make sure the devices would work in my 550EX (the 550EX does not have a sync port).  So, a quick email to them revealed that a neat little device from the folks over at Flash Zebra would make the Cyber Syncs compatible.  A mere $14 later and the device arrived late last week (while I was in SC).  So, next month the Cyber Syncs will be making their way to my doorstep.

In the meantime, I have these Cactus triggers, and I thought with the inclusion of a sync port, perhaps I could jerry-rig something together.  With the sync port going out to what looks to be an RC-mini, and the receiver also going out to an RC-mini, I needed a way to join two RC-mini’s together.  A quick dig through my various buckets of cables and connectors revealed a dual mini that is normally used to connect to headphones to a single audio.  Worth a shot, since it’s only about $50 total invested.  I connected everything together to get this:

On your left is the trigger that came from Cactus, to the RC male.  A reducer on that took it to an RC-mini male.  In the center is the well-hidden PC-sync device that came from Flash Zebra.  (For a better picture, see below…)  A female sync port on that was able to connect to the male sync port that was included with my Cactus gear.  That also went to an RC-mini male.  These are both connected on the right to the y-connector that you would typically see two headsets connect to the same audio source.  The technology is the same, so it’s worth a shot right?  (No pun intended…)

I fired off a test shot from the 40D and it worked!  So, how well would it work?  What kind of reliability would there be?  I took the flash into the next room and fired the trigger from a further distance away…about 20 feet.  Flash!  Then I took the trigger around the corner and fired it.  Flash!  How cool is that?  Another set of tests was needed.  One where radio waves wouldn’t bounce all over the place – outside!  If you recall, I interviewed Scott Eccleston from Weekly Photo Tips a while back, and a recent post of his armed me with a good testing method of the Cactus triggers.  Armed with the inspiration of this video, I enlisted the aid of my wife and took to the great outdoors.

I began with a fresh set of batteries in both the trigger and receiver, as well as the flash.  Starting from ten steps away from the flash, I tripped the shutter – flash!  Twenty paces – flash!  Thirty paces – flash!  Fourty paces – nada.  Hmmm…tried again – nada.  So, I moved back to 35 paces – still nada.  A couple steps closer and it flashed again.  About four more tests at this distance and I had 100% flash rate.  Starting back to my wife, I counted the paces, 1-2-3… all the way to 33 paces.  At an average gait of 3 feet per pace, that’s an outside range of 99 feet!  Considerably better than the ST-E2 and at a third of the price!

For posterity’ sake, and since I am in a very casual way reviewing the PC-sync adaptor from Flash Zebra, here’s a better shot of just that device.

Also for posterity sake, here’s a view of the trigger that attached to the hot shoe of the 550EX:
