Description from the seller
This is an Olympus Electronic Flash G40, a vintage flash designed for Olympus IS film cameras.
Features: The flash head can be rotated both horizontally and vertically for customized lighting.
Power: Runs on 4 AA batteries.
Functionality: It features a comparison table on the flash itself.
In good, working condition.
The Olympus G40 flash, designed for the IS-series film cameras (such as the IS-1000/2000/3000), does not fully fit or natively work with modern Olympus digital models (Micro Four Thirds or E-System).
Fit/Mount Issue: The G40 is designed for a proprietary, older hotshoe system. While it may slide onto a modern standard hotshoe, its electrical contacts do not align with modern digital cameras, and it has been reported not to fit securely or at all on some, including older digital models like the Camedia C-5050.
Functionality Issue: The G40 uses an older, proprietary TTL system (dedicated to IS/OM series) that is completely different from the digital Olympus TTL system. It will not function in automatic TTL mode on a digital camera.
Potential Usage: The only way to use the G40 on a digital camera is in Manual Mode or by using it as a generic "slave" flash (if triggered by other means), as the G40 lacks a standard, universal hotshoe connection.
For modern Olympus digital cameras (OM-D, PEN, E-system), it is recommended to use FL-series flashes (FL-36, FL-50, FL-600R, etc.) or modern third-party options (e.g., Godox/Meike/Neewer with Olympus-specific TTL).
