SPEEDLITE 300EZ

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.
