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.
A wireless master function (optical) is built-in that allows multiple flash units to be controlled for creative lighting effects. Through 4-channel optical light pulse transmission, the 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. Best of all, the 90EX has a standard Canon hot shoe mount that makes it compatible with all Canon EOS SLR cameras.
The product comes supplied in a plain white box, instead of the manufacturer's packaging. It includes all the manufacturer's accessories.
Top Customer Reviews
This flash is very effective within 15ft. And with the addition of a diffuser ( not included ) the results are very nice. The 90ex is a great buy because it is both a pretty good flash, as well as a master trigger in a wireless system for newer eos cameras, two things that you would need to spend far more on to achieve. I highly recommend you purchase a diffuser along with this flash, because as with other flashes, the resulting images are far more improved. This would make a great back up for a pro doing portraits away from home/studio or as a first time flash user, or anyone just shooting at closer ranges that wants something a tenth the size of their regular flash. Oh, I forgot to mention, with NMH AAA batteries this flashe's recycling time is blazing and seems to flash forever!
It runs on 2 AAA batteries, which will only last for a few dozen shots, so it would be wise to pack additional batteries. On the plus side, the flash with batteries only weigh a couple ounces, so it won't weigh you or the camera down.
This camera will also serve as a cheap wireless controller for other Speedlites, enhancing its usefulness.
The original list price for this flash was $149, which is silly considering the much more powerful 270ex II only lists for $20 more. However, it can be had for under $50 online (including a white box version here on Amazon).
There are no external controls on this flash, so any adjustments will have to be made from the camera.
Bottom line: If you own an EOS-M, consider this essential equipment. Otherwise, consider it to be a wireless controller that can also act as a pop-up type flash.
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.
