What is the Red Flag on the Olympus Trip 35? How It Prevents Underexposed Photos

What is the “Red Flag” on the Olympus Trip 35?

A simple mechanism that helps prevent failed shots

The Olympus Trip 35 features a small but important safety mechanism known as the “red flag.”


It appears when there isn’t enough light for proper exposure and prevents the shutter from firing—helping you avoid underexposed shots.

This system is also found in other Olympus auto-exposure cameras, such as the Olympus PEN EE-2 and Olympus PEN EE-3.

When it appears

The red flag shows up in low-light situations—such as indoors, at dusk, or in shade—where proper exposure isn’t possible.

When it doesn’t

With enough light, the flag stays hidden and the shutter works normally.

This simple behavior is what makes the Trip 35 so easy to use.

Final inspection

Before shipping, we carefully test each camera:

• Does the red flag appear in low light?
• Does it stay hidden in proper light?
• Does the shutter operate correctly?
• Does the light meter respond consistently?

Ready to use

The Trip 35 is simple—but only when everything works as it should.

Each camera is thoroughly checked so you can enjoy shooting with confidence from the very first roll.
