I have read on here numerous times (and seen the Offical Canon Instructions) one ofthe disadvantages with the STE-2 is that is must have line of sight with the flash to be able to work. Well at least in my limited testing I would have to say that it is not all true. Take a look at the attached images. I was playing/testing my ST-E2 with my 550ex at work today. I put the flash on a stand with the IR facing the wall behind a cloumn (see 2nd photo). I went to the other side of the room (23 feet away) and lined up almost with the column edge. As you can see in the photo the flash is nowhere to be seen but the flash easily fired. Yes the room had no lights on, but I turned them on increasing the light in the room by almost 2 full stops (1/5-1/30) and the flash still fired. My next test will be outside in the sun to see what results I get.

Indoors you certainly don't need line of sight. I'd be interested to know how you got on outdoors - I haven't tried that myself yet at longer distances.

that's actually my next test. besides a distance test inside. Now I don't expect it to rival a radio popper in all circumstances by any means, especially outside, it's more to see what the actual limitations are beyond what everybody apparently regurgitates from Canon.
I did one more inside with the flash off of the stand and on feet so I could get it next to the wall. I had it behind a metal shelf and turned the IR toward the wall, nothing...then I turned the IR toward the room and pointed the camera towards where the flash was hopefully going to hit and the flash fired..from about 15 feet away. Pleasantly surprised so far.;)
I will keep this updated as I do more tests.

Couple more quick non-scientific test results
Outside range (at night) roughly 71' with line of site
Put the flash behind a tree on the ground, had the IR pointing out and was able to fire the flash from a distance of between 35'-40' at a rough angle of 30-40 degrees..(blinking IR not visible) and ST-E2 pointing straight ahead. Of course the further back I went the shallower the angle needed to be. But at least you can hide the flash and still trigger it within reason..again at night..;)
Daylight tests tomorrow

Indoors the IR signal will bounce off walls. I scarcely think about flash placement indoors with the ST-E2 because it is very reliable in my experience.

Outdoors things get tougher. As a rule it is a good idea outside to try and face the flash units towards the camera.

I'm not surprised at the indoor results. The results of using the STE-2 outdoors has been so inconsistent I have moved away from using the 580 flashes altogether. It does work if you are close and in line of sight outdoors but your results will vary depending on elements in your environment. Nonetheless, interesting results and it is certainly worth the testing that OP has done to get a sense of what their equipment is capable of.


My life is like one big RAW file....way too much post processing needed.

And thats what I found out, as long as I have the IR turned towards the camera/ST-E2, I can reasonably hide the flash and still trigger it...which goes against Canon's documentation on the ST-E2..you know it HAS to have line-of-site..

1 thing I forgot to mention on the distance test last night, the flash wasnt immediate, when I pushed the pilot button to trigger, there was a heartbeat of time difference..I quess for the signal to reach the flash..
