Canon Speedlite 420EX Features & Specifications

Though TTL compatible with all Canon EOS cameras and the manual-focus T90 SLR, the Canon Speedlite 420EX flash is also E-TTL compatible with all A-type bodies: EOS-1v, EOS-3, Elan 7 / 7E, Elan II/IIE, Rebel 2000, Rebel G, and EOS IX and IX Lite. The E-TTL function gives you features like high-speed FP sync mode and FE lock (spot/partial flash metering). The swivel head of the 420EX lets you bounce the light off the surrounding surfaces, giving your images soft, professional-quality lighting.

This flash also works as a wireless “slave” flash with EOS-1v, EOS-3, Elan 7 / 7E, and D30 bodies. The remote flash firing is controlled entirely by a master unit–such as the Speedlite Transmitter ST-E2, Speedlite 550EX, or Macro Ring Lite MR-14EX–connected to the camera, making it fast and simple to set up. When used with the EOS-1V, EOS-3, or EOS D30 cameras, additional features such as lighting ratio control and modeling flash are also supported by the 420EX.

I use the 420EX and found it to be sufficient for what I do. I have used it to create portraits and it did fine. I have tried to use it at weddings/receptions and it just couldn’t keep up with my shooting. It would also over heat because of the type of shooting. However, using it for not so intense situations, it’s a great option.

I’ve used this flash on several occasions, it’s enough if you don’t expect too much …
It’s not that powerful, it’s therefore a little slow to recycle and it lacks manual settings …
Other than than, it’s a good unit
