The Camera Company, Boston, Massachusetts

This exciting new addition to the EOS System combines compact size and affordability with an added dose of features and sophistication. Improving on the previous model, Speedlite 420EX, the new 430EX can now be set into manual flash mode (full power~1/64). Flash compensation can be set on the flash unit, and manual control of the flash zoom head is now possible. Improvements in its circuitry make recycle time 40% faster, and since it is compatible with Canon's wireless E-TTL, it can be used as an affordable "slave unit."
