The Canon Speedlite 430EZ is a dedicated electronic flash unit introduced by Canon in 1989 for the Canon EOS film SLR camera system (starting with the Canon EOS-1).
Key Features and Specifications
Guide Number: 43 meters (approx. 140 ft) at ISO 100 (or GN 116 ft at 50mm, ISO 100).
Modes: A-TTL (Advanced Through-The-Lens), TTL, Manual, and Multi-flash (stroboscopic).
Zoom Head: Motorised internal zoom covering 24mm to 80mm with manual override.
Head Movement: Tilts from 0° to 90° and swivels horizontally.
Power Source: Operates on four size-AA batteries (alkaline or Ni-Cd).
Compatibility:
Canon EOS film SLRs using A-TTL/TTL metering.
While it will function with digital SLRs and mirrorless cameras in manual mode, because digital bodies use E-TTL or E-TTL II, I would not recommend it for digital cameras. You would need EX-series or EL-series Speedlites
