Canon Speedlite 90EX (EOS-M) - master capable on all EOS bodies?
« on: November 10, 2012, 11:38:08 AM »
just found this post on German foto community http://www.fotocommunity.de/forum/d-slr-fortgeschritten/drahtloses-blitzen-mit-speedlite-fuer-alle-eos-359176 which claims the small external Canon speedlite 90EX which was released alongside the EOS-M seems to work as a wireless master flash [line of sight, optical] on all Canon EOS DSLRs. Mastering capabilities almost equal to the 580EX.
3 groups and best of all HSS mastering on top.

I cannot verify, sicne this speedlite is not available yet were I live and furthermore I have a 7D with pop-up master flash built in. Although that one will NOT do HSS mastering.

If confirmed, this would be a really interesting and cheap option for owners of EOS bodies without pop-up flash, namely 5D/2/3 and 1D/s/X.

just checked the Canon website and it confirms the 90EX works as master-flash.

http://www.usa.canon.com/cusa/consumer/products/cameras/speedlite_flash_lineup/speedlite_90ex#Features
For a number of advanced lighting setups, the Speedlite 90EX can be used as a master transmitter to control multiple flash units - wirelessly! Through 4 channel optical light pulse transmission, the Speedlite 90EX can control up to three groups of slave-enabled flashes, controlling power from 8:1 to 1:8 in 1/2 stop increments. It can transmit up to approximately 16.4 ft. indoors, up to 23 ft. outdoors.

@wickidwombat: thanks.

So aside from ST-E3 and 600EX-RT (with radio and line-of sight wireless) there are now 3 options for light-pulse line-of-sight wireless mastering available from Canon. Each with it's own set of advantages and disadvantages:

* master-capable flash, eg. 580EX/II
functionality: master triggering, 4 channels, 3 groups (A,B,C), 1. curtain and HSS; AF-assist (both IR and flash) 
Upside: powerful fully featured flash functionality; downside: bulk/weight, cost   
   
* ST-E2 - same capabilities as 580EX/II, AF-assist (IR);
Upside: small&light, "cheap"; downside: no flash functionality on its own

* Speedlite 90EX
same as 580EX and ST-E2, but no AF-assist; basic, weak (fill) flash capability 
Upside: small& light, cheap; Downside: no AF assist functionality

Plus another option available on newer EOS bodies with master-capable pop-up flash:
* 7D (3 groups of slaves), 650D (2 groups), 60D, 600D (1 group)
functionality similar to 90EX, minus HSS master capability, but plus AF-assist (flash only) 
Advantage: built-in, no extra item, no extra cost; Downside: available only on newer APS-C bodies; no HSS in  wireless mode

Unfortunately neither one of the "small, light & cheap" options has all desired functionality. 

And regrettably none of Canon's wireless mastering options offers 2nd curtain sync whereas all of Nikons's wireless CLS options do provide 1st, 2nd curtain and HSS in wireless mode - but they got no radio wireless as of yet. ;-)

I'm still amazed why Canon didn't add 2nd curtain wireless at least to the new 600rt protocol - since rt is not backward compatible anyway, it would have been easy to add this feature as ettl-iii. But maybe it'll be on the 660rt :-p ?

I'll have to check again but I was fairly sure second curtain sync was able to be enabled in the camera menu when i had the 90 ex on it, the tiny size and weight are definately a good plus for this little guy

@wickidwombat: could you please take a look into this feature, once your time allows? I am fairly certain 2nd curtain Sync will not be available in wireless mode. However, I would be more than happy if I were proven wrong on this one and would immediately order a 90EX. :-)
Thanks!

In wireless mode the menu option for 2nd curtain sync changes to high speed sync.

big gripe with canon and not allowing 2nd curtain on off camera flash

A couple of observations from using the 7D. The on-camera flash must fire for the trigger to work. (The flash has no effect on the exposure as it is synced to fire before the shutter opens, but it must fire.) This has a tendency to overheat the flash very quickly. Once it overheats, it shuts down until it cools off. The net result is that you are out of business until it cools down. Embarrassing and frustrating if you are in the middle of shooting a portrait.

I don't know if the small 90EX fires when you use it to trigger a slave or if it is subject to the same overheating, but I wouldn't be surprised if it does overheat quickly, given its small size. Just something to be cautious about.

After several embarrassing and frustrating incidents, where the flash quit triggering my 580 II's, I decided to go for the Yongnuo knockoff of the ST-E2. I'm not a professional, so I could not justify the cost of pocket wizards. The Yongnuo is less than half the price of the ST-E2, has worked very well and even rotates in the hotshoe so it can be aimed better at the strobes (something the RT-E2 doesn't do). If it dies on me, I can always use the 7D's on-camera trigger, but this way I have a backup. Just something to factor in.

The effective range (about 5 meters) is very limited, plus it states that AF assist beam does not fire in wireless mode

Just out of curiosity... I am away on holidays and don't have the manuals lying around. How many meters does the ST-E2 cover, as well as the 580 EX II and 600 EX RT  that I have too? I have only used the ST - E2 to control my three flashes in a studio, so I have not been concerned about the meters yet, but it is interesting.

This is so awesome. I got the 90EX bundled with the EOS M (and it wasn't advertised as such, so a true bonus), and now I can use the 600EX-RT truly off camera at last! What an awesome function to add to such a tiny flash unit.

I was going to suggest this and their lights rather than screwing around with optical triggering.  There is another thread here somewhere (here) discussing what it can do.  The idea of firing Canon-type wireless lights with a different-brand body is intriguing.

I'd probably do better to invest more time and less money.

Here's a quick question....

Can you use the flash to trigger two off camera groups (yes), while at the same time using it to provide fill flash?

If it works like the 60d's built in flash the answer has to be yes.... but I'm not sure.
Upgrade  path.->means the former was sold for the latter.
