Easy and intuitive operation
Designed for intuitive operation and as a perfect match for the EOS M Digital Camera, the Speedlite 90EX offers a number of sophisticated flash functions that are remarkably easy to use, even for beginners to the EOS line of accessories. Many functions can be controlled effortlessly through the camera’s menu system, such as the AF assist beam (used to ensure accurate AF in low light situations), Canon’s amazing E-TTL II flash metering, FE lock and flash exposure compensation. Even color temperature information can be transmitted back to the camera with a simple touch, so users will achieve great results.

Complex Lighting Setups, Wirelessly And Easily
Wireless master function (optical) allows multiple flash units to be controlled for creative lighting effects
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 ½ stop increments. It can transmit up to approximately 16.4 ft. indoors, up to 23 ft. outdoors. With the Speedlite 90EX controlling each light source according to the specific parameters of a shot, the creative possibilities are endless!

I purchased the Canon 90EX for one reason, to wirelessly trigger my off-camera Canon 430EX II flashes. At the time of ordering this little guy, there weren't any reviews specifically concerning the 90EX's master functions or compatibility with the new Canon 6D, so I though I would contribute to the group. Hopefully you find this review helpful. Feel free to ask any questions in the comments section.

Let's get started!

Is the Canon 90EX any good? The answer is, "YES!!!!" The 90EX is an awesome alternative to everything else out there that will wirelessly trigger your flashes. Here is quick glimpse at what's good and not-so-good...

* Wireless Slave Groups - You can fire with A:B and A:B C groupings. You can have multiple flashes in each group creating an infinite number of lighting varieties.
* Manual Adjust - flash settings can be manually adjusted from on-camera. From 1/1 all the way down to 1/128 on the 430EX II's.
* E-TTL II - Works' perfectly. Also, E-TTL ratios are very handy for quick setups. From 8:1 to 1:1 to 1:8 in half stop increments.
* HSS - High Speed Sync works up to 1/4000 (that's the highest shutter setting on the 6D). HSS can be set from in camera when shooting in master mode with flashes that are capable of shooting in HSS. When shooting with just the 90EX and no external flashes, HSS is not available. You'll only be able to shoot up to you max sync speed (1/180 on the 6D).
* Curtains - both 1st and 2nd curtain work. 2nd curtain is not an option in wireless mode though.
* Easy to Use - The unit has one button, a battery door, an LED light, and a hotshoe lock....that's it. All controls are run from in the camera menu.
* Small - Very compact!

I bought the 90EX as a Master for my Canon T2i and Canon 430EXII flash. Wow, it works incredibly well! I use my 430EXII flash mounted on an umbrella at various angles as a slave flash, and the 90EX has had a 100% success rate in triggering my 430EXII, without having direct line of site indoors.

I also like that it uses AAA batteries rather than 2CR5 like the Canon ST-E2. It comes with a little soft pouch (see my photos above that I uploaded), I would have liked a harder pouch, but it's fine.

The flash is also very small, which I really like. I was shocked how tiny this is (see my uploaded photos above). On the back of the flash (see photos above), there is a power button, a battery cover, and a lock for the flash shoe area. No other buttons, as it's controlled through the camera menu which I like very much.

Overall, I highly recommend the Canon 90EX as an economical Master for wireless flash if your camera is able to control the flash through the menu system.

This flash was introduced recently for the mirror less EOS M compact line of cameras Canon started in late 2012.
However, the flash works with all other Canon cameras with a hotshoe. With pre EX series flash cameras, you lose some critical capabilities for correct exposure, like ETTL, or the II version thereof.

However, with cameras with exterior speedlite control (please look up your cameras manual) you gain the ability to control off camera flashes through optical (using light/from flash as opposed to radio, like cell phones) signals. This is the least expensive solution from Canon for this off camera flash control from a compatible camera. Only the Canon 7D (and 60D) have built-in flashes that do this and none the full frame cameras even have built-in flashes. This tiny flash can control several off camera flashes in separate groups A, B, C and vary the ratio of light the groups throw out all using ETTL II within its limited 15~20 ft range!

Also helps focus assist cameras in low light levels using light bursts, though this can be turned off. Just don't expect it to light up group photos outdoors outside its range. At best, use it as a fill flash on its own outdoors.

The 90EX was designed for the EOS M kit, but works on any E-TTL capable camera. I bought the 90EX to serve as the missing "popup" for my 6D and trigger off-shoe E-TTL Speedlites.

The Guide Number of 30 ft/9m at ISO 100 means the 90EX has power output similar to a popup flash. So what's the 90EX good for? As a flash, it works great for close fill-in flash, snapshots or macro when used on an off-shoe cord. It is not not powerful enough for group shots. With Sanyo Eneloop AAA batteries, recycle is about 2 seconds at full power. I haven't tried alkaline batteries but reviewers report alkaline recycling takes twice as long as rechargeable batteries.

The unique feature of the 90EX is the wireless E-TTL master function: triggers slaves with auto or manual modes controlled from the camera flash menu. In this regard it's better than the dedicated ST-E2 master: brighter and more reliable trigger, controls 3 slave groups rather than only two and is useful as a flash when not performing master duties. The 90EX uses light pulses to trigger so line of sight to slaves is required. Swivel the slave body so the sensor faces towards the 90EX. Reflective surfaces indoors (e.g., white walls) will often carry the trigger pulse even if faced the wrong way. However, outdoors they will not trigger without direct line-of-sight.

Other than an on-off switch, there are no external controls. To set options, use the flash menu on 2007 and newer EOS cameras. On my 6D, everything is operational except for FEB and high speed sync. However, high speed sync is available in master mode (trigger mode). Flash exposure compensation can be set with external camera controls, the QCS or flash menu.

What I like best about the 90EX is it's so small and light I can keep it in my bag all the time. My larger Speedlite gets left behind if I'm not positive I need it. All in all a wonderful petite flash for snapshots, close fill and as an E-TTL controller.
