If I were to announce…

that Canon introduced the world’s best interface for flash control–a Speedlite interface that was big, colorful, and easy-to-understand–you would think it was news…right?  You might also think it was fantasy. Well, it’s real and I’m three years late in making that announcement. It happened in mid-2007, when Canon released the 1D Mk III camera and the 580EX II Speedlite. The world of off-camera flash should have shook back then, but I did not feel anything. Thereafter, with every new Canon DSLR annoucement, there should have been major aftershocks. We Canonistas have had a revolutionary Speedlite user interface in our hands for three years and no one is whooping about it (not even the marketing department at Canon). Are you still scratching your head trying to figure out what I’m talking about? It’s the ability to control every aspect of an EX II Speedlite from the back of our cameras–on menus that are big, colorful, and easy-to-understand.

I discovered this capability quite by accident about a year ago when I bought my first 5D Mk II and paired it up with my then year-old 580EX II. I literally tripped into the ‘External Speedlite Control’ menu while looking for something else on the my camera’s LCD monitor. So, for the past year, I’ve gone from being barely able to find the ‘External Speedlite Control’ menu to thinking of it as an indispensable part of my Speedliting technique. I’m sure once you come to understand the potential, you’ll see it as indispensable too. And, if you’ve never seen a good reason to upgrade to an EX II Speedlite, you’ll likely change your mind about that too. I sure have.

My days of struggling with Canon’s miniscule icons on the Speedlite LCD panel are over.

I’ve not been shy about sharing my thoughts on the challenges of the Canon Speedlite interface. In fact, my July 2009 rant on PixSylated (‘My Canon Speedlite Wishlist‘) has been expanded by the comments of nearly 400 other photographers – which is the record for all of my blog articles. Much of what I discussed in the Wishlist has to do with icons and menus. Well, for the past month or so, I’ve been thinking that it’s time for a re-write of the wishlist. Now that I have the on-camera menu control of my Speedlites, I’m a much happier camper.

Pop quiz #1: which of the above two interfaces do you find easier to understand? Your assignment is to disable the on-camera master Speedlite so that it does not throw on-camera flash at your subject (most often, that’s a very good idea). On the left, you have the 580EX II LCD. You have to look for the three lines coming out of the Speedlite icon and then figure out which of the buttons to push so that the three lines go away (hint: when in doubt, always try the ZOOM/EverythingElse button). On the right, you have the menu choice from the LCD on my 7D. Even without my reading glasses, I can see it clearly.

If the Speedlite has a button or dial for it, you can read it on your camera’s LCD.

So, what Speedlite functions can you control on your camera’s LCD? Every last one. Seriously. You can even Zoom the Speedlite from the back of your camera.

^^^ Change the mode on your Speedlite

^^^ Change the zoom setting on your Speedlite. (This does not change zoom settings on slaves).

^^^ Change the sync mode for your Speedlite.

^^^ Turn the wireless system on or off.

^^^ In Manual mode: set the power level for each Group

^^^ Change the ratio mode (E-TTL) or the number of groups (Manual).

^^^ Set the A:B ratio.

^^^ Set Flash Exposure Compensation for Group C.

^^^ Change the settings for Multi/Stroboscopic Mode: output, hertz, and number of flashes

Custom Functions on-camera. A new way to translate the Dead Sea Scrolls.

If you’ve ever tried to change a Custom Function on a Canon Speedlite, you’ve encountered what is probably the most-cryptic system of digital control in the entire photo universe. Having to pry open a hidden cover and move microscopic switches would be easier than decoding the nuances of 0 and 1 on a Speedlite LCD.

Hidden tip > The one Custom Function that I always want to disable is the one that saves power by putting the Speedlite to sleep. I carry lots of batteries. I want my Speedlite to stay on and vigilent; waiting for me to give it something useful to do. So, on the 580EX II, the 430EXII, and the 430EX, I set C.Fn-01 to 1. On the 580EX, I set C.Fn-14 to 1.

Now, cue the Halleluia Chorus, Canon’s world’s-best camera LCD system also gives you the ability to read all of the details about a Custom Function and its options in plain English (or French, or German, or whatever language you have your camera set to).

Pop quiz #2: which of the above two Custom Function interfaces do you find easier to understand? Silly question, I know. Left: LCD panel on the 580EX II. Right: LCD monitor Canon 5D Mark II. Both screens are asking the same question.

Putting the pieces together.

So, what do you need to get this great functionality? You need the right Speedlite (you have 3 choices) AND a compatible camera (you have 17 choices). The reason that I never discovered the on-camera control for the first year that I had my 580EX II is that I used it in a 5D. The original 5D cannot communicate with a Speedlite this way. It was when I parked the 580EX II on my first 5DM2 that the magic door appeared.

For the Speedlite, it must be on of the following:

• 580EX II
• 430EX II
• 270EX

For the camera, it must be the EOS 1D Mark III or have been introduced after the 1D Mark III. Basically every Canon EOS and Powershot camera introduced from mid-2007 on has this capability. Here’s the current list of cameras that will communicate with a compatible Speedlite:

• EOS-1D Mark IV
• EOS-1D Mark III, 1Ds Mark III
• EOS 5D Mark II
• EOS 7D
• EOS 50D, 40D
• EOS Rebel T2i, T1i, XSi, XS
• PowerShot G11, G10, G9
• PowerShot SX 1 IS, SX 10 IS, SX 20 IS

So where do you find it on the camera menu? Good question. It’s not in the same place or labeled the same way on all cameras. Rather than balloon-up this article even more, I’ll do a follow-up post soon. Basially you want to look for something that says “Flash Control”, “External Speedlite control”,  or something similar.

^^^ left: Rebel T2i, center: 50D, right: 5d Mark II

Maximizing the power of the Canon LCD-control system.

Obviously, the initial benefits of controlling your Speedlite from the LCD of your camera is that the screen is much easier to read and understand. So, if you have just one Speedlite, the system will remove the obstacles to activating the functionality that you want.

The real magic happens when you turn on the wireless system and move the master off-camera. I’ve written elsewhere how fond I am of using an extra-long E-TTL cord. (Read this article for the basics.) So, think about the power of moving your master Speedlite off-camera and still being able to control all of its functions from your camera. Once you get the hang of controlling the Speedlite from the back of your camera, it will save you valuable time during a shoot.

Here are the three main advantages provided by this unique combination of shooting wireless with the master moved off-camera on a long E-TTL cord.

You can use an off-camera master to add valuable light to the shot. Normally, if my master is in the hotshoe, I will disable it so that it does not fire during the shot–so that it does not throw on-camera flash at the subject and kill the quality of light. Don’t worry–the disabled master sends the instructions to the slaves. Moving the master off-camera, means that it can now communicate instructions to the slave(s) AND contribute valuable light (meaning the it creates light that has interesting shadows).

You can position the master in a position where the slaves can see it. The Canon user manual assumes that all the slaves will be in front of the camera and within the 80º spread of an on-camera master. I’ve never found this to be typical of how I shoot multiple Speedlites. Also, if a slave has to look towards the sun to see my on-camera master, it will likely not see the instructions. This happens frequently when I’m shooting high-speed sync outdoors in full sun. So, being able to move the master off-camera means that I can put it in the most advantageous spot for all the slaves to see it.

You can put the master and slaves inside a softbox. The challenge of using a softbox with a Speedlite is that the Speedlite throws all its light out the front–so there will likely be a hotspot at the center of the softness. In contrast, a studio flash has a cylindrical tube that throws the light sideways. While I am quite fond of the convenience of the Lastolite Ezyboxe Hoshoe (which mounts a single Speedlite at the back), when I need more light, I use the Westcott Apollo. The unique design of the Apollo is that the flash is mounted inside and pointing backwards. This allows the light to swirl around before it flies through the front. So, by using the Lastolite TriFlash and an extra-long E-TTL cord, I can mount a master and two slaves inside the Apollo and control everything in E-TTL or Manual from the back of my camera. Amazing.

Feel free to gloat, just a bit, Canonistas.

^^^ Left: Canon 5D Mark II with 580EX II. Right: Nikon D3x with SB-900.

Now, here is another truly mind-blowing bit of news…the Nikon CLS does not have this full range of on-camera LCD capability. Sure, I’ll say it again. Nikon CLS does not have the breadth of Canon’s on-camera capability for controlling Speedlites.

Last week, I was tutoring a friend about how to use her Nikon Speedlights. At a particularly troublesome point, I said, “let’s pull it up on your camera’s LCD, here like this…”. When we could not find a way to do it, I phoned Mr. Hotshoe’s assistant to ask where to find the on-camera Speedlight menu. He couldn’t think of how to do it and put Mr. Hotshoe on the line. There was some of the usual Canonista-to-Nikonian confusion in our dialogue. I was eventually asked by Mr. Hotshoe “why would you want to do that?” Later, it occurred to me that this question was analogous to being asked by my dog, Ruby, why she would want to see the world in color. Not that my sensei, Mr. Hotshoe, resembles a golden retriever in any way…other than perhaps in his enduring loyalty to friends, but I digress.

Not wanting to doubt the ubiquity of Mr. Hotshoe’s expertise in all things Nikon, I still could not believe that this technology does not exist in Nikonlandia. So, chalking it up to the possibility of one of our lost-in-translation events, I phoned my buddy MD Welch (his Notes-From-The-Field blog here) — who shoots Nikon corporately by day and Canon for his personal work. If anyone could translate my query from Canonista into Nikonian, MD could. So he went to work the next day, fired up the D3x with an SB-900 and went searching. When he came up dry, he phoned a couple of other Nikon pros and asked them. “Nope” was his succinct report. “Can’t do it on Nikon.” I now call him Mr. Bernstein and refer to myself as Mr. Woodward, because I think we’ve discovered something really big that no one is talking about.

So there, if you’re feeling puny because you shoot Speedlites rather than Speedlights, strap an EX II Speedlite onto your camera, find the ‘External Speedlite Control’ menu and go to town.

55 Responses to How To Control A Speedlite From The Back Of Your Camera

  1. Mike Spivey says:

    I agree with all the stuff you said. Now, we need one more thing to make it really good. I've got "External Speedlite Control" on the My Menu page. But I have to press that, then "Flash Function Settings", then turn the dial 2 clicks to "Wireless Set" and press to get to the good stuff. What I really want in My Menu is "Wireless Set" but I can't figure out how. Doesn't seem like a lot, but when you have a model waiting on you, it's an eternity.

    Am I missing something?

    • Syl Arena says:

      Mike – I've let Canon know that it would be great if menu had option to open up exactly to where it last was. The system would totally rock then. Still, since I do this frequently, I've gotten to be really fast at it. I'd rather have menu system capabilities as is, than not have it at all.

  2. brian from nj says:

    Great stuff! This rocks with the 7d's wireless capability.

  3. mamo says:

    this sounds very interessting! but this is not available in the good old 5D? :-(

  4. Simon Jacobs says:

    This post is a joke? Please?

  5. Frank says:

    This is great stuff! Now, when are you releasing your Speedlite book? Been waiting for it so i can finally learn how to use flash on my 5DM2.

  6. Harry Lim says:

    Mike: I wonder if maybe you can set one of your custom function settings or add the setting to your "favorties" menu to cut down on the time. Just an idea, I haven't tried it myself.

    Syl: Good info, but this doesn't work with the pocket wizard system. :(

  7. Mike Spivey says:

    I agree. I guess the issue is that My Menu does not support sub-menus. But I too, am getting used to it. Punch, Punch, spin the wheel backward two clicks, punch.

  8. Having spent a couple of hours on an outside shoot last night, fiddling around in the dark trying to control my 580EX II and my 430EX that's slaved to it, your article warmed my heart, Syl! Tried controlling everything with the 580 attached to my EOS 550D's hotshoe – fab!

    However, I use a long E-TTL II cable to get my 580 off the camera, so I can actually use it to create useful light as well as the master flash. Unfortunately the flash controls on the back of the camera disappear when I use the cable. Does this mean I'm stuck with using the 550 only on the camera's hotshoe? If so it dies seem a bit if a waste. Any thoughts?

  9. Syl – Thanks for responding. I can't actually see a brand name anywhere on the cable or the hardware at either end. All it says at the camera hotshoe end is: 'For Canon E-TTL II'. This is the one: http://cgi.ebay.co.uk/OC-E3-5m-Off-Camera-Shoe-Co

    I will certainly try the space-shuttle-style turn-it-all-off-then-turn-it-all-on-again approach though, as you suggested. If not, I'll order one of the leads from flashzebra. Many thanks.

  10. Matt Vanecek says:

    Yeah, this doesn't work with PocketWizards. I have MiniTT1 and Flex5. A cord would be super inconvenient. Probably a PW translation issue, but to do anything, I have to lower the light stand, muck about (set the power, turn on 2nd curtain, zoom in/out, etc.). PocketWizards work with the ETTL, but not with the settings, I guess (and I'm not sure the auto-zoom works, now that I think about it. Will have to try when I get back to my gear….

    I've gotten in the habit of using manual mode on the flash, as it's just so much more precise and controllable than ETTL, but it'd sure be nice to be able to control that from the camera via the PW, just like it was a long cord… :)

    Thanks,
    Matt

  11. Brian Dolphin says:

    Syl,

    I think Matt brings up a good point that I was curious about myself. I would like to be able to use this functionality without a cord. Have you found a way to make this work with Pocket Wizards Mini TT1 or anything else for that matter? I was in Adorama today and asked them about this. They weren't sure if it would work. Even if this doesn't work now though the Mini TT1 has a usb port to update the firmware. Do you think this is something they would look into? It seams that at the point we would have the easy user interface on the camera with the range and reliability of the PW system.

    PS. Thanks for the comment on your site about the workshop in NYC. Glad that you are having the workshop. I looked this morning and the link worked great. Adorama updated there site finally. See you in October.

    Thanks,

    Brian

  12. Paul Stackhouse says:

    Brian – Last week I emailed PW the same question about controlling flash via menus when using a TT1 and I got back: That feature will not work; however we hope that future firmware upgrades will make this possible.

    I am still looking into getting TT1/TT5's, a nice feature is the increased power in high speed sync mode. According to this article http://www.robgalbraith.com/bins/content_page.asp… you get more power using a TT5 than having it on camera.

    -Paul

  13. Alexander says:

    Its fun to read about Nikon…
    Nikon has on-camera menu for CLS control on each camera with pop-up flash.
    With pro-cameras you have full control CLS with your flash that work as MASTER-flash.

  14. Hi Syl,

    I'm wondering if anyone else who has tried this with a 580EX v1 has the same issue as I do. I would LOVE to be able to control everything from the back of my 5D MkII, but with the 580EX on the camera I only get a limited menu on the back of the camera. I can change the bottom three menu items, but can't change the top three (eg. Flash Mode, Shutter Sync, and FEB). The bottom 3 menu items aren't nearly as important to me as the top 3, so I'm wondering if it is normal for the 580EX to limit the menu items on the 5D MkII.

    If anyone knows anything about this, I've love to hear from you!

    Best Wishes,
    John

    • Syl Arena says:

      John – The 580EX was introduced in 2004 — three years before the introduction of the communication link that I detailed in the article. To get the functionality that I describe, you have to have one of the three current-generation Speedlites (580EX II, 430EX II, or 270EX) and a compatible camera body (virtually all models introduced from mid-2007 on).

  15. Peter P says:

    Hi,
    For those of us who are not fond of wires to be tripped over during a photo shoot, the ST-E2 remote flash controller is great – It controls my 2 speedlites from my 5DmarkII, grouped into a and b.
    ( Example shots: http://pep.smugmug.com/Restricted-Galleries/Team-… )
    But with this setup, you loose the nice in-camera flash manageability that you so enthusiastically write about. So Canon leaves me these options:
    1) Leave Master flash on camera – not good, for reasons you describe in the article
    2) Get a long wire – not good in 2010 unless you like web-weaving your studio
    3) buy another EX580II as on-camera master with flash turned off. The solution, the Canon salesguys would love. And a bl**** expensive double of my ST-E2
    Right? – or have I overlooked something??

    • Syl Arena says:

      Peter – I'm not a fan of the ST-E2. The #1 reason is that, with the ST-E2, the slaves have to be in a relatively narrow zone in front of the camera. I often put slaves behind me or out wide on the side. If you're indoors, then the ST-E2 signal might bounce off the walls and hit all the slaves. Outdoors, under the California sun, this coverage is impossible. I have a handful of other reasons…guess I'll have to dust off that draft article I started a while back and get it published soon.

    • brosepix says:

      "you loose the nice in-camera flash manageability"

      Peter, I am surprised to read this. Not that I have any evidence to the contrary, but I would have thought that the ST-E2 could be controlled by the camera in the same way as a master flash. It has full E-TTL II functionality, which seems to me to suggest it can cover all those C.Fn functions that you canset in the menu.

      Would be pleased to know anything more about this.

      Thanks.

      Neil

  16. TomH says:

    This is great stuff. The custom functions are now in English, without pressing "1". I can't believe I hadn't seen or heard of this before. Thanks!

  17. Gove Johnson says:

    I have a 40D and 580EXII, and the Menu choices for External flash func. setting say "This menu cannot be displayed. Incompatible flash or flash's power is turned off." The manuals for both devices claim this flash is controllable from this camera's menu. What gives?

  18. Bryanphotopilot says:

    For you pocket wizard Mini/Flex folks, they have announced (& started shipping) the AC3 that goes on top of your Mini in the shoe and gives you control (ETTL + or – 1/3 stops OR manual power) for each of the 3 channels A/B/C, and you can have multiple flashes set up in each channel. Mine should be in the big brown truck early next week.

  19. Jim says:

    Great article. Thanks for posting all this. I just bought the Canon 60D, sold my 580EX and am shopping for a "compatible" flash.

    You can add the 60D to the list of cameras with this functionality. (edit your article).

  20. Peter says:

    I have a friend that just went to your workshop and now he thinks that us Nikon users cannot even do high speed sync. So what are you telling those people. I do use Canon by day and Nikons by night. And the Nikon flash system has alwys been more accurate and easier to us, but now with the newer Canon bodys and the II versions of the flash I would call them pretty even. I have done a ton of HSS for outdoor portraits with the Nikon and it works great 90% of the time. Also have used the 40D's and the 580 EX II but only have one so never hard to try. I do like that feature on the Canon and also did not know about it. But now I'm back to doing everyting old school for outdoor flash. My new boss does not believe in new things.

    • Syl Arena says:

      Peter – My comment about HSS on Nikon only related to the fact that there is not a dedicated button on the Speedlights for it. As you likely know, you have to head into the Speedlight's menu system to activate HSS. With a Canon Speedlite, you just push the button on the back of the Speedlite.

  22. Leo says:

    Nikons definitely have this functionality, in fact most bodies allow control of speedlights via the pop up flash. You don't have to buy an expensive Master device to use speedlights off camera (though you can use an SB900 or SU800 to increase range). Both my D700 and D7000 allow control of 3 flash groups in TTL, manual or any mix of these via the built in flash. Many, many older Nikon bodies allow this too.

    Canon is only just starting to introduce this functionality in camera now… most Canon pro bodies don't even have a pop up flash so you have to spend more $ to get something Nikon provide free.

    Hi there! You have mentioned that when you bought your first 5D Mk II you got to pair it up with the 580EX II.
    Do you have any idea how to set it to work in a wireless way? I mounted on 5DMkII, set everything, unmount, and didn’t work in a wireless way. Am I missing something or do I need to buy some extra equipment?

    Thanks in advance.

    • Gerry says:

      you still have to fire your built-in flash to activate the 580 EX II with your 5D mkII and 7D mk II. Canon uses the strobe of your built in flash as transmitter. which is the main reason why I switched to Nikon, this wireless capability minus firing the built in flash.

      • Syl Arena says:

        @Gerry. Just to be clear, there is no flash built into the 5D-series. You are correct that a flash will be seen as this is how the master (on-camera flash or external Speedlite) sends the instructions to the slave(s). However, just like in the Nikon system, the master can be set so that it sends the instructions to the slaves and then remains dark when the shutter opens. Canonistas call this “master disabled.” Nikonians call this “commander mode.” With Canon’s new 600EX-RT, the two-way communication between master and slave is entirely invisible in the new radio mode. Perhaps it’s time for you to consider switching back?

  25. agelos says:

    i have a canon eos 40 d
    does anyone knows why?

  26. Jules Boisvert says:

    While it is great to control the speedlite with the camera menu setting, using a long cord cause me an issue because the camera think that the speedlite is hotshoed on the camera and if the head of the speedlite is straight-ahead direct flash (no tilt and no pan) then E-TTL II is using the distance between camera and subject to calculate the flash power.

    This means that if the flash is positioned closer to or farther from the subject than the camera or using a diffuser then the flash metering (E-TTL II) may be thrown off.

    For people using long e-ttl cord, what do you do to bypass this issue? Do you tilt or pan a little the flash head to make sure E-ttl II does not rely on distance?

    Thanks

    • Syl Arena says:

      I’ve not found this to be a problem. The distance data is only a small portion of the ETTL calculation. The majority of the ETTL process is based on measuring the actual light coming back in through the lens–which works fine with long ETTL cords.

  27. Jules Boisvert says:

    Thanks Syl for sharing your experience.

    So, maybe I have a problem with my 5d mark iii, because when I use my speedlite with a Lumiquest Omnibox and an E-TTL cord and if the speedlite is farther from my subject than my camera then I always got an underexposed picture (in e-TTL II mode)…but if I use the wireless mode instead of an E-TTL cord then my picture is well exposed. In both cases the camera and flash are at the same position with the same settings…the only difference is one use the E-TTL cord and the other one use wireless.

    This problem is much less evident when the speedlite is closer to the subject than my camera (in this situation I got pretty same exposure).

  31. Andrew L says:

    Thank you for bringing this forward, Syl. I saw your B&H video a while ago but came across a specific flash and I wanted to ask about its compatibility. I came across a either a used 550ex or a 580ex. I’m not sure which one it was. I have a 5D Mark II and a 580ex II with a long E-TTL cord. At the moment I’m looking for an affordable slave for the kit I just mentioned. I can’t seem to get my 420EX to work as a slave with what I have, so I was unsure if the used unit would work. Do you happen to know which features might not be compatible? For example, high speed sync, groups/ratios, any other normal features that would be present if I were shooting with two 580EX II units.

    I have checked to make sure all of my abbreviations are correct in terms of Mark II models etc.

    Thank you for your help!

    The flash unit will not flash. I go to the “external speedlite control” window and select it. Then select “flash function settings” and upon selecting this I get a message saying “this menu cannot be displayed. Incompatable flash or flash’s power is turned off”. My flash is on of course. What next?

    • Syl Arena says:

      @Jim –

      The message indicates that your camera cannot communicate with the Speedlite. Make sure that the flash is pushed forward fully in the hotshoe. Also, make sure that the locking lever is closed tight. If this does not work, use a pencil eraser to gently clean the pins on the flash and the contact points in the hotshoe. Sometimes a bit of oil can break the communication. Be sure to blow the eraser rubbings cleanly away.

  35. Brian says:

    Is there any way to use the master speedlite off camera without having that ettl cord from the hot shoe? Can you use transmitter? I would love to be able to control my slaves/master from my camera without having to keep the cord connected. Is that possible?

    • Syl Arena says:

      Brian – By definition, the master must be connected to the hotshoe. So, if you have a transmitter, like the ST-E3-RT in the hotshoe, then the off-camera Speedlites are all slaves. Without a transmitter, ETTL cords are the only way that I know of to move a master off-camera and have it control slaves.

Trying to use the 580EX-II with the on camera menu results in an incompatible flash message. Then I turned everything off and back on and again end everything worked as the article state. Suggest that those with this problem try turning everything off, re-installing the flash and then turning everything. I don’t know why but it worked for me.
