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.
I ended up buying this flash after buying the EOS M. The "M" doesn't have a flash and there are many situations where you need one. The 90E was made for the "M" and really should have some with it. I bought it based on the size, but Canon sells other more powerful flashes for less money reducing the value of this flash. Functionally it does the job and plays nicely with other flashes.
