|  | | |
| | | The fixed head and lower power flash output of the 300EZ makes the 430EZ a more attractive second-hand buy for a type B camera, though the Speedlite 300EZ could be good value if this is all you need. A-TTL flash mode. Guide number of 30 (ISO 100m) at 70mm zoom head setting. Coverage down to 24mm. EOS magazine, December 2003, page 38 Type: energy-saving, automatic, electronic flash unit uses A-TTL metering system to measure light reflected from the film surface. Clip-on type with directly coupled contacts. For exclusive use with EOS cameras.

Flash control system: TTL series control system with preflash function
Flash exposure level control: a maximum of 1.5 BV steps in the A-TTL mode when subject brightness is more than BV5 according to the camera’s metering system
Film speed setting: automatically set by the camera
Automatic shooting distance range: | |
A-TTL normal flash | Approx. 0.7 to 17m | A-TTL rapid-fire flash (min.) | Approx. 0.7 to 3.9m | A-TTL rapid-fire flash (max.) | Approx. 0.7 to 12m |

Based on EF 50mm f1.8 lens at ISO 100. (The automatic shooting distance range extends according to film speed.)
Out-of-coupling range warning: if a subject is too far away, the shutter speed and the aperture value blink in the viewfinder at the first stroke of the shutter button
AF auxiliary light: ultra-bright red LED (peak sensitivity: 700mm) Projected at subject for AF flash photography. The effective distance is approx. 0.9-6m (3-19.7ft.)
