Review - Canon Speedlite 600EX-RT

[RustyTheGeek]

An efficient light weight lighting kit is more valuable than an expensive heavy lens that you will rarely use.

I guess I'm not sure how two or three 600EX-RT flash units along with possible stands, light modifiers and batteries can be considered "light weight" compared with a lens but you're right if compared to a bunch of studio strobes. As for subjective value or assumed rarity of use compared with a lens, my flashes come out a lot less than my lenses in the types of walk around journalistic shooting I do. And these large flashes are actually larger than most lenses, the 70-200/2.8 being one exception. (I use a small RD2000 flash most of the time but I would love to have something similar in size from Canon that was controlled ETTL wirelessly directly out of the camera.) YMMV. My flashes would be used a LOT MORE if I could control one off-camera flash straight from the camera and not be forced to have a big ass flash attached to my hotshoe for the sole purpose of controlling another big ass remote flash that was the only one I wanted to use in the first place. (Carry two large flashes just to use/control the single active large off-camera flash = stupid PITA to me.) The ST-E3-RT controller is about the size of the RD2000 flash I use now but still requires me to hand carry the 600 flash because I can't mount the 600 anywhere. That's dumb. At least put a hotshoe on the controller. But no! Find a pocket, backpack or between your knees for that flash when you can't hold it all the time in your other hand when focusing, etc.

Hence the natural thought progression of ... lose the ST-E3-RT controller all together and put that functionality into the camera itself. Now just carry one flash and let it live on the camera when not used off camera. One flash, multiple uses. Simple but for some reason not within Canon's grasp to offer.

Putting ST E3-RT funtionality into the camera is a great idea and I think it is "within Canon's grasp to offer" ... but IMO it would have negative imapact on the camera with:
[list type=decimal]
[*]decreased battery performance of the camera (as it also needs to provide additional power for that function)

[*] If they produce new powerful batteries to support the camera with the in-built ST E3-RT functionality, the cost will add up not only for the camera but also in having to buy spare batteries (going by Canon's recent pricing strategy, I bet it will be very expensive) ... also those who are not interested in wireless flash photography will have to pay for a feature that they do not want.

The rt control needs only short bursts of radio activity, I doubt it'll be such a wifi drain as constant wifi operation with high data rates (eos remote).

The real drawback would be that like the 6d, there has to be some part of the camera w/o metal casing to reach enough distance/power and/or low battery consumption - but unlike gps this part hasn't to be where the built-in flash is (Rebels) or would be (6d).

Hi all:

Have been accumulating the system as I can afford it, I now have the ST-E3 controller and four flashes. A couple of comments after the review:

-The price of the flash has actually been slowly falling. The last two I paid $529 from Adorama in person.

-One thing I'm unhappy with is that if you're shooting in low light you really need a 600 as a controller if you want the IR focus assist. Of course you can turn off the flash on the shoe if you're using it as a controller with other flashes off camera.

-It's easy to mix with studio strobes. If you use the ST-E3 to trigger a 600EX being used as a hairlight or something, the 600EX will then optically trigger a studio strobe in a softbox or whatever. I use it together with my older Elinchroms like that.

-As far as the filter issues, I use a Honl speed strap along with their filters. I'm sure there are other workarounds as well.

-It definitely took time with the manual to figure it all put, plus looking at Neil's Tangent site, and some of the videos at canonlearning, but I'm quite comfortable with the system now and love it.

-I wounder why a controller can control just about anything on a slave, but not the zoom range. That would have been cool.

Overall am very happy with the 600EX-RT system.

Fyi: Celebrating the first anniversary of the 600ex-rt I put up a poll about the rt successor of the 430ex2: http://www.canonrumors.com/forum/index.php?topic=13229.0

1. Wireless flash RF wouldn't affect battery life that much. It doesn't seem to affect the 600 series flash's battery life much does it? The flash only uses four AA batteries, no special high capacity batteries there. Although now that I think about it, perhaps an integrated high capacity battery system on a full size flash might be a good thing with even faster recycle time and longer life. Let me think... use the same LP-E6 battery in the flash too... hmm. That might be something cool... Eh, Nahhh.
2. Cost is rarely a reason to not do things in photography. Canon charges somewhere around 10 million percent profit margin already and everyone seems to pay it for whatever they choose to release lately. Just look at the 1D-X, 1D-C or 1D 4K or even the 5D3 as examples. Not to mention the newest lens prices lately running into the stratosphere. Somehow I don't think integrating flash control into the camera will make much of a diff.

Or Canon would rather sell the same body worldwide and deal with the flash separately. Different countries have different RF regulations.

 

[RustyTheGeek]

Well, good point and you may be right but don't they already have different models for different countries? That's just part of the game. Just a few more hoops for the lawyers to rangle and the design techs to manage. Shouldn't be a show stopper. Maybe pick an available freq that works in both countries? Or have two freq. Pretty easy to manage two different freq or RF modules at the assembly level I would think.

Not a good idea to use the camera battery. Li-ion chemistry is optimal for sustained, moderate-current discharge, and a flash needs brief, high-current discharge to fill the capacitor. A Li-based battery in a flash means long recycle times (that's one reason why the popup flash on a Rebel/xxxD is very slow to recharge, whereas a 430EX II with NiMH batteries can keep up with the first part of an 8 fps burst.

Yeah, excellent point neuro. Forget I said it. Something in the back of my mind was dogging this idea and that's why I did the "eh... naah" thing at the end. I couldn't put my finger on it. Plus, more expensive batteries that can't be charged in the field are also a drag. Since eneloop batteries came on the scene, my flashes work great for a long time and I loooove those eneloops. Sanyo needs to somehow apply this same reliable and foolproof battery technology to the economy.

 

[Lawliet]

Li-ion chemistry is optimal for sustained, moderate-current discharge, and a flash needs brief, high-current discharge to fill the capacitor.

True for LiCo cells, you comfortably get about 15W out of something camera sized, i.e. about 5s recycle time.
But change the cobalt for iron phosphate and the tide turns, you'd fry the caps and the flashtube long before the battery gets remotely taxed - cells rated for cont. 30C and peak 100C+ discarge means multiple full pops a second. (Profotos B4 uses such a battery, something 1/10 the size for a 50Ws flashgun? 8) )

Also, I have been buying gels in the UK from FlashGels who have precut a bunch of Lee filters for the new system.

http://flashgels.co.uk/shop/index.php?main_page=index&cPath=13&zenid=eh3ud620p3jnd0bjjq2702f616

I actually rather like the canon gel holder and the way the gel clips into it. Feels a lot more reliable than the other systems I used on the old 580s.

That's awesome! Long way to send for some gel's - hopefully someone over here will do the same - price is less than Canon's too. I still want my own die-cut: yes I could cut my own with an exacto blade but who has time for that?

There's really no need to Die Cut filters for the Speedlite 600 filter holder - If you look closely, there are some cut out slits which allow you to use a 3"x3" square piece of gel - Those are pretty easy to cut with a paper cutter or scissors.

Laziest guy in the world right here!

I just have *so* many cut out rectangles with little velcro pads on them. So using them with my stack of Honl straps is just the "old way" of doing things I'll stick to. I kind of like manually controlling my WB anyway.

 

[RustyTheGeek]

Just for the record, my bitching is more about wanting more functionality and redesign than cheaper price. Just swapping optical for radio communication isn't a big game changer in my book and doesn't deserve my money. I would like to see Canon do something truly great and shake things up using the big advantage they own... integrated camera functionality together with several models of great performance flashes with reliability and simplicity of use. After all this time knowing what is out there in the aftermarket and designing the current new camera bodies and new flashes, this is all they came up with? How unimaginative and incremental. Yawn.

I don't think it can be done as easily as you think. Different countries have different RF regulations and it may not be practical/possible to design for all of them in one unit. Imagine having to a different 5D III model depending on where you live.

Perhaps, the next generation will bring the comm to wi-fi, which is pretty standardized. Nikon just came out with the WR-1 system -- not a flash, but it still needs to be wired to the camera. It looks like Canon will have a more elegant system for a bit longer.

hey is anyone try 600 ex rt +st-e3 with canon 6d ?

is the HSS work with 6d?
because i want to shoot in outdoor at the sunlight with over 1/2000ss
thx

According to Canon any Canon DSLR made in 2012 onwards can do HSS ... i.e. Yes 6D + 600 EX-RT can do HSS

 

[Marsu42]

Page 51 of the manual covrs functionality with different age cameras. The 6D is a post 2012 camera so has no restrictions.

... but the information Canon gives is not (entirely) correct because even post-2012 cameras like the 5d2 are reported to work with full speed remote flash just fine, it's just that Canon - for marketing or warranty reasons - doesn't say it works and that the ui doesn't support rt and group mode.

 

[Marsu42]

I believe, whilst there is a little wiggle room, the Canon specs are right for consistent and accurate flash.

Thanks for the info (other 1d3 users might appreciate it), it's just that I recently researched the 5d2+rt and didn't find a single report of it not working - though it only has 1/200 x-sync and ymmv of course.

Either way, the 6D has 100% functionality in HSS with the ST-E3-RT and 600EX-RT.

Right, plus it has the newer in-camera ui - and for the guaranteed reliability (though at only 1/180 x-sync) I'll also get the 6d.

 

[JVLphoto]

Yes, but I'd like to see a series of images shot with ETTL in HSS from a 5D MkII to verify correct operation if it was an important function for me. Like I said, my experiences are that it is nowhere near as consistent as ETTL below HSS.

Having said that, it is not a feature I have needed, HSS yes, but not the combination of ETTL and HSS. I am sure when I get post 2012 bodies I'll use it though HSS does work faultlessly in manual mode with multiple channels and ratios on my pre 2012 bodies.

As for the RT system, I really like it, even with the limitations my bodies have, and, when compared to the competition, I don't feel the price is too high. When I was making my choice for intelligent radio triggers the only other option I ended up seriously considering was the Phottix Odin, now they have some really nice functionality!

I also want to put it through some HSS paces. It's just been pretty crappy weather here and none of my shoots have been outdoors. Spring can't come soon enough!
