I figured that there was nothing to lose for the price, and so early this morning I ordered this radio flash trigger from China:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270395697932

I could have purchased the single receiver ones for about half the $45.00 price tag (WITH FREE SHIPPING TO CANADA)- but decided on this package with 2 receivers and the interesting flash mount with 2 hotshoes. Also this one has adaptors to attach it to my Elinchrome and MultiBlitz studio flashes - whereas some others only triggered with a hotshoe.

I have been leary of ordering such products from overseas, however my 3D Animator friend recently ordered a ridiculously cheap wireless shutter release for his Nikon D200 (about $10 compared to Nikon asking $130), from Ebay - and the shipment arrived safely from China and has worked just fine for his purposes.

They are a little flimsy and probably more of a throw away item when something gives up. At any rate - they let me know that it is on its way, and I am looking forward to trying this unit out for the same purposes I did when 20 years ago I had my much more expensive Quantum Radio Triggers.

We'll see how it goes and I'll report my findings here.

In some further research I have found that apparently the distances don't live up to the 100 foot (30 meter) claim - - - but there are some relatively simple hacks that can supposedly increase the distance as much as 10 fold:

Increase effective distance on 'ebay' flash remote trigger transmitter with antenna

And this from Flickr which also includes adapting the battery power pack:

Here is a video talking about the the Gadget Infinity remotes (similar to what I have ordered):

Actually one reason that I chose the particular unit that I did, over the other similar ones (even from the same supplier) - - - was that it had 2 hotshoes on the one receiver. I think that would be vital to anyone who like myself, use 2 portable flash units together firing through one umbrella. Apparently these inexpensive triggers, will fire off other units if there are too close together as demonstrated in the above video - - - and so that would preclude using 2 flashes with 2 receivers on the same light stand. I hope that this is a viable solution to that problem.

Last night I also ordered from a different company, a "IR Wireless Remote Control for Olympus E-420 E-520 E-3" for the price of US $8.49 - - - as well as a "Battery for Olympus E-30/E-3/E-520/E-510 BLM1 BLM-1" for the price of US $14.99. FREE shipping to Canada at that. I got the notice this morning that these products have been shipped to me.

I have never had a wireless RC for my camera and will likely not use it much, but can't go wrong to have one at that price. I have several brand name BLM1 batteries for my cameras, but can never have enough during the course of a long shooting day. I also have 3 third party Optex batteries that have served me well. The price of the Olympus BLM1 battery is $89.95 CDN, the Optex is $49.95 CDN (I just purchased another 2 Optex, last week) - I'm really curious to see what $14.95 US (about $18.00 CDN) will give me.

Crazy delivery time - - - I ordered battery, camera remote, free pouch (for ordering 2 items)  from China on July 2'nd - got it today July 9'th. I'm impressed.

I finally got around to editing the footage that Richard and I took last year - - - that dealt with the ISHOOT Radio Flash Trigger testing and antenna modification.

First up was the Shutter Sync Speed Test. I fired the flash at popular sync speeds of 1/125'th, 1/250'th, 1/320'th, and 1/500'th second. The flash fired in all cases, but was ineffective at 1/500'th of a second with my Olympus E-3 top sync of 1/320'th. At any rate - contrary to some claims that I have read on the web, stating that these inexpensive units don't sync properly - - - I found that not to be the case with this particular unit:


<div><embed type="application/x-shockwave-flash" src="http://www.youtube.com/v/EFjmNLzAm-Q&amp;ap=%2526fmt%3D18&amp;rel=0" width="650px" height="392px" wmode="transparent" quality="high" allowFullScreen="true" allowScriptAccess="never" pluginspage="http://www.macromedia.com/go/getflashplayer" autoplay="false" autostart="false" /><noembed><a href="http://www.youtube.com/v/EFjmNLzAm-Q&amp;ap=%2526fmt%3D18&amp;rel=0" target="_blank">http://www.youtube.com/v/EFjmNLzAm-Q&amp;ap=%2526fmt%3D18&amp;rel=0</a>


Next on the agenda was the Flash Distance Test without the Antenna Modification - so that we had a standard to base further tests on. I fired the flash outdoors on a bright sunny day. Starting at a distance of 20 feet, I then moved on to 60 feet, then 100 and 200 feet in deep shadow. The flash was still firing and so we headed out to the nearby road and maxed out the distance for successful firing of the flash - - - at around 600 feet. I was quite pleased with those results:

Here is a video demonstrating the process that we took with the Antenna Modification. Unfortunately I ran out of video tape during the section where we actually did the soldering of the wire onto the board. The unit had been assembled by the time we got another camcorder rounded up. But I think that this little video will give you a good idea what the insides look like and how the process goes as we saw it anyway:


<div><embed type="application/x-shockwave-flash" src="http://www.youtube.com/v/IRXZSunsxTU&amp;ap=%2526fmt%3D18&amp;rel=0" width="650px" height="392px" wmode="transparent" quality="high" allowFullScreen="true" allowScriptAccess="never" pluginspage="http://www.macromedia.com/go/getflashplayer" autoplay="false" autostart="false" /><noembed><a href="http://www.youtube.com/v/IRXZSunsxTU&amp;ap=%2526fmt%3D18&amp;rel=0" target="_blank">http://www.youtube.com/v/IRXZSunsxTU&amp;ap=%2526fmt%3D18&amp;rel=0</a>


After testing the unit with the antenna modification, I came to the conclusion that with this particular device it made little difference in firing distance over the distances achieved with the built in stock antenna. This video contains my conclusions:


<div><embed type="application/x-shockwave-flash" src="http://www.youtube.com/v/e4njE74DVjA&amp;ap=%2526fmt%3D18&amp;rel=0" width="650px" height="392px" wmode="transparent" quality="high" allowFullScreen="true" allowScriptAccess="never" pluginspage="http://www.macromedia.com/go/getflashplayer" autoplay="false" autostart="false" /><noembed><a href="http://www.youtube.com/v/e4njE74DVjA&amp;ap=%2526fmt%3D18&amp;rel=0" target="_blank">http://www.youtube.com/v/e4njE74DVjA&amp;ap=%2526fmt%3D18&amp;rel=0</a>


Why do I call it a "sweet little baby" ? I am comparing to my expensive Quantum radio slave that I used to own - that required a large sender to be clipped on my belt, as well as a large remote unit that I generally velcro'd to the light stand holding my remote flash and wired into the flash (I'm sure since I had that unit, they have become a bit smaller and more versatile).


One thing you may notice in this video as well as others where flash units are being tested - is that even though a flash is firing, it may not be visible in the video. This is simply a result of the short duration of these portable flash units - along with the faster shutter speed being used with the video camera. You'll just have to trust when I say that the flash fired - - - as  I saw it with my eyes and was able to verify it on my cameras LCD after the shot was taken.

Something new that I discovered about this flash trigger, is that being it has a jack that will allow connection to the cameras PC terminal - - - I am able to use my on camera FL50R flash (or any other auto flash) in TTL mode as I always do, and have the trigger fire external flashes that may be positioned around the room (they may be set to Manual or Auto output).

This could work well for ambience or accent lighting in the corners of a room at a wedding, event or party - where I can still roam freely with my camera and flash in Aperture TTL mode.
