How long is the range of Canon ST-E2 speedlite transmitter in practice?

I just ordered a used but working Canon ST-E2 speedlite transmitter because it was so cheap that it cost practically nothing. However, the ST-E2 hasn’t arrived yet. My flash has support for ST-E3-RT as well. My camera doesn’t have the “easy wireless” flash, meaning ST-E2 is necessary for this camera model.

How long is the range of a Canon ST-E2 transmitter in practice (not in optimal conditions)? I understand that it uses infrared. Is the infrared so powerful that it can bounce off walls indoors? How about outdoor shooting, does a ST-E2 work well outdoors?

Does ST-E2 require line of sight when shooting outdoors? If a flash is situated behind the camera in outdoor conditions, will it trigger? If not, is it possible to put some kind of reflector (umbrella?) in front of the camera but still outside the field of view to bounce infrared backwards?

At least my Canon flash has the sensor in the front, but fortunately the head turns 180 degrees, so I can always position the sensor in such a manner that it’s facing the camera.

The reason I’m wondering is that I ordered a new ST-E3-RT which is taking quite long to arrive (the shop where I ordered it from still doesn’t have the product, and it will take 2 weeks for them to have it in stock), before finding the used ST-E2. If it seems ST-E2 is enough for most conditions, I could cancel the ST-E3-RT order the cost of which is approximately 5 times the cost of a used ST-E2.

Apparently, professional photographers used infrared triggers for a long amount of time until Canon created a radio based system, so it can’t really be that bad, right?

As another benefit of ST-E2 apart from the price, it works with older Canon equipment, meaning I can order used flashes which are quite decently priced when compared to new Canon flashes. As third benefit, it saves 50 grams of weight compared to the radio model.

Can a Speedlite 430EX II be used on a Canon EOS 6D?

I recently purchased a Canon EOS 6D, but my Speedlite 430EX II is not working with it. Is this flash not compatible with the 6D? When I go to Menu –> External Speedlite Control, flash firing is enabled.

However, when I press ‘Flash function settings’ or ‘Flash C.Fn settings,’ it says “This menu cannot be displayed. Incompatible flash or flash’s power is turned off.” (power is definitely not turned off :))

What is the issue?

Yongnuo YN600EX-RT II Flash Speedlite

I have a typical newbie question. I’ve done HDR for a couple of years now and I see its limitations, so I’m ready to start using flash.

I do real estate photography with the Canon EF-S 10-18mm lens on a 77D. I’m not quite comfortable using manual mode, so I set it on Av with f/6.3. Almost all the homes I shoot are less than 4000 sqft.

I plan to use a flash or two on stands just outside of the frame. I assume I’ll have to use a diffuser because of the ultra-wide angle lens.

I’m thinking about buying this flash. My question is, is this overkill? If not, what would you recommend?

Also, will it work in E-TTL mode using the Canon Easy Wireless system?

Thanks, Bruce

Why isn’t my Canon Speedlite 580 working on my 5D Mark II?

I was shooting at night and my flash was working perfectly, all of a sudden I tried taking another picture and it stopped working. I was using it on ETTL mode, the pictures looked underexposed with no signs of flash, then I tried using it in manual, what happened next was an overexposed picture because of the flash’s light. Because I realized it was kinda working in Manual mode I set the ISO to 100 and a very fast shutter speed and it did the job, but this means that there is no way I can use my flash with the right exposure. I tried using my flash on my canon 60D and it works perfectly. Hope someone can give me an answer?

Unable to trigger my Speedlite YN565EXIII via optical trigger using a Canon 750D (Rebel T6i)

I own a Rebel T6i and a Speedlite Yongnuo YN565EXIII. I’ve tried several times to trigger the flash off-camera (on a tripod with a softbox) and I’ve had some very unsatisfactory results.

With the speedlite on a tripod I’ve set it to ETTL slave mode (Sc mode). On the camera on the camera I went to Flash Control >Built-in flash settings in there I’ve set the following settings:

  • Flash firing: Enable
  • E-TTL II meter: Evaluative
  • FLash sync. speed in Av mode -> 1/200
  • Channel: 1
  • Group: A

Here’s a image of the flash settings as it is right now: Flash Settings

On Buillt-in flash settings I have the following:

  • Flash mode: E-TTL II
  • Wireless func: (Set to the icon of the dedicated flash only)
  • Channel: 1
  • Firing Group: All
  • Exp. Comp: 0

Here are some images of my camera settings:

First screen: First screen

Second screen: Second screen

I have the sensor turned to me as I take shots of my speelite on a tripod. I’m literally taking pictures of the optical sensor:

Here’s how the speedlite it’s positioned: Speedlite position

I think its important to say that Im shooting on full manual mode. Now to the problems.

1) Most of the times when I use the pop up flash to trigger the speedlite, the built-in camera goes off, however the speedlite isn’t triggered, even though I’m pointing the built-in flash directly to the sensor at a distance of around 1.5 meters (about 5 feet I guess). The speedlite goes off on an estimate of one time every ten attempts. The batteries are new and I wait about 5 seconds between each new attempt.

2) When the speelite goes off, most of the time it doesn’t affect the exposure of the image. It’s like, it’s out of sync with the camera or something like that. My room it’s pretty dark, and even when the speedlite goes off the image it’s completely dark.

3) Sometimes (a good amount of times) the pop-up flash of my camera doesnt go off even though its set to go off and my room it`s completey dark. Does the built-in flash has a recharge time or something like that?

I’ve also tried using the speedlite (and built in flash) on manual slave, instead of E-TTL slave, but got the same problems.

Im trying to learn off-camera flash techniques and I was relying on the optical trigger, as I dont have a wireless one, so if anyone has a suggestion on how to fix this I`m eager to try.

Can I use my old Canon Speedlite 277T with my new Canon dSLR?

Actually it’s my dad’s flash that he bought many many moons ago to use with his old Canon T70. I don’t have a flash but have borrowed his to try out, but he mentioned that some flashes will send too much voltage down to the camera and can damage the camera. That’s the last thing I’d want to happen to my new baby (a 5D Mark II).
