Pocket-sized & inexpensive off-camera E-TTL II flash
I was on a family break last week when the EOS M broke cover, and haven’t seen one in the flesh as yet. However the small Speedlite 90EX that was launched has intrigued me and got me thinking;
Is this a low-cost, pocket-sized flash master for all EOS cameras?
With a guide number of 9m at ISO 100 it’s got less power than just about every built-in flash on an EOS DSLR. However I’m wondering – and still waiting to find out for sure – if it could be a fantastic low-cost master flash for Speedlites using pulsed light. According to the specifications on Canon’s website the Speedlite 90EX acts as a master, and can control three groups of slaves. This makes it more functional than the more expensive Speedlite Transmitter ST-E2 which controls only two groups.
The down side is the need to use a post 2007 camera to control the new Speedlite as it relies on settings made via the camera LCD and has almost no external controls itself.
EOS 40D/EOS 50D & EOS 5D Mark II users this is for you
Get a Speedlite 90EX to upgrade your EOS to wireless flash control
If you have an EOS 40D, EOS 50D or EOS 5D Mark II and a single Speedlite 430EX II this new Speedlite 90EX could enable you to try off-camera wireless flash with full E-TTL control pretty cheaply. Up until now you would need an ST-E2, Speedlite 580EX II or very much more expensive Speedlite 600EX-RT to be the master on the hotshoe. This little lightweight flash should make controlling any of the other slave flashes simple and effective.
I can’t wait to see if my thought turns out as I hope it will, anyone with inside info or facts then please get in touch.
