I wanted to comment just to state the obvious... obvious to some, maybe not so obvious to others. But before ordering these I emailed Cowboy Studio's with a couple simple questions... then never got back to me. In fact, it was like I sent my email into space... don't expect this company to be on top of customer service via email. I suggest calling them, although, when I DID call them I got an answering machine (yes, like... and answering machine). I bought these triggers anyway... so I figured I'd answer my own questions in case others had the same questions.
Q1.) Do they work only if they can clearly see each other (ie. line of sight) or will they work if the flash is hidden somewhere, like in a softbox or just around a corner somewhere?
A1.) They indeed do NOT need to `see' each other. My first test I had the flash in my kitchen, then I walked 3 rooms away behind my fireplace. Not only was I 3 rooms away, but in between were the standard walls made of plaster as well as a brick wall from the fire place. Yup... it fired perfectly. Next, I put my flash inside one of my wife's leather pocketbook's. I figured if it would fire inside a closed leather pocketbook, it would have no trouble inside a cloth softbox. Indeed, the flash fired perfectly.
Q2.) Does it work like TTL... or... can I at least adjust the flash power from the back of the camera?
A2.) No and no. However, if you set your flash to M, you can adjust the power this way. If you set your flash to 1/2 in M mode, it'll fire at 1/2 power. If you set it to 1/4 in M mode, it'll fire at 1/4 power.... you get the point.Read more ›
Range is not a big issue for me, I've not hit the limit of these Cowboy Studio ones. Honestly, if you exceed the range on these you better be finding a bigger light source than the Speedlight your probably trying to trigger. The wireless is pretty robust as well, I triggered strobes with these through two walls with no problem.
The build quality is better than the generic guys but maybe a hair less than the PocketWizards. Doesn't matter though you can buy yourself about 10 of these for the price of two PocketWizards. So break them, loose them, blow 'em up or whatever and never worry about it. They're built well enough to not give you false pops too. So far I've had exactly one misfire, and that was because of the transmitter not being screwed down tight into my cameras hot shoe. Great performance from these so far.
No TTL support, but I shoot Nikon and none of the high end brands support real iTTL either. This may be a bigger issue for Canon guys who can find radio ETTL options on the high end stuff. Manual flash is not a big deal and being wireless means that these are most likely going to be on stationary light sources anyhow.
The sync speed on these is pretty great, cheap generics don't sync very high usually. My old generics wouldn't sync higher than 1/180, these are fine at 1/200th, bringing them on par with the PocketWizard who is suppose to sync at 1/250th but never does.Read more ›
Basically you stick the transmitter into the camera hotshoe and attach the receiver onto the flash. Then power up the flash and use it in Manual mode to set the strength (e.g., 1/4 strength). Make sure batteries are fully charged and inserted (transmitter will light up if charged, if not, replace the 23A 12V inside; the receivers use 2 AAA batteries each), and that the transmitter and receiver are on the same channel.
Take a test shot. If it's too bright or dark, adjust exposure compensation/flash compensation and/or flash strength until it's just right. Then you can fire away without having to re-adjust!
I bought this set in case one of the receivers breaks; that way I don't have to order another receiver at extra cost.
Way cheaper than many alternatives like Pocket Wizard.... yeah you don't get TTL with this, but frankly even with TTL you may have to make manual adjustments anyway.
It arrived in a nice looking box and was well protected.
First thing I did was bought batteries to test them out. You do not need a flash to test them out, but I recommend you do to no be miss led. For example; I pressed the test button on the trigger and a little red light on the receiver indicates that it received a signal. Now I did this right when I put my fresh batteries in. It did show some miss firing on one, but, when I tested it with my flash (SB900)it never missed fired not one time. It appears to me that the light doesn't pop each time you press the trigger button. However when the flash is on the receiver, it has worked every time.
I Tested it with 2 walls(about 30 feet straight line)between the flash and camera and not one time has it miss fired. I took about 70+ shots so far. Not bad for day one. I do expect them to miss fire but so far the stats are great.
As for the build, It has metal hot shoe mount and metal screw mount. The tightener is plastic and the shoe is plastic. You don't need to tighten the trigger at all. It fits snug.
Update. I got my other flash last week and both receivers still hasn't miss fired.
