The short-lived Canon Speedlite 420EZ camera flash was produced from 1987 until 1989. The flash differs from Canon's newer 420EX flash, though it was considered a top-of-the-line model when it was introduced.
Features
The 420EZ can swivel and tilt, and it also has a zooming flash head that will internally adjust to the focal length of any shot. The zoom range is 24 mm to 80 mm, with stops at 24, 28, 35, 50, 70 and 80 mm.
Function
You can use manual control over the flash output and the unit's built-in controls boast a power range from 1 to 1/32. The flash is not compatible with digital cameras but does support A-TTL and TTL automated flash metering with compatible film cameras.
Considerations
Canon's 420EZ does support second-curtain synchronization through a control on the back panel, which also features an LCD. The stroboscopic flash has a range of 1 Hz to 5 Hz, the unit has a Save Energy mode and it weighs 350g. The flash runs on four, non-lithium, AA batteries.
