FJ80 Speedlight overheating?Updated 21 days ago

Here are a few simple ways to keep your speedlight from overheating:

Lower the Power:

If you're indoors, try raising your camera’s ISO or opening up the aperture. This helps the FJ80 work on lower power, so it won’t heat up as much. In TTL mode, increasing the ISO means the speedlight automatically needs less power, which helps keep things cool.

Adjust the Beam Angle and Get Closer:

Set the zoom of the speedlight to a telephoto length so the light just covers your subject. This allows the speedlight to use less power whether you’re in TTL or Manual mode. And if possible, move closer to your subject. This also allows the speedlight to use less power.

Do not use Modifiers Unless Needed:

When you're shooting fast, it’s best to avoid using things like softboxes or diffusers on the flash—they trap heat and make the light work harder. If you need to use a modifier, stick to single shots or take a few breaks between bursts to let the unit cool down.

What if it still overheats?

If the speedlight overheats, it’ll either slow down or stop firing for a bit to cool off. When that happens, try lowering the power or shooting at a slower pace. For longer sessions, a steady, moderate pace works well—most speedlights take about 2.5 to 4 seconds to recycle.

Does the FJ80ii do better with heat?

Absolutely. The FJ80ii has better heat dissipation, so it handles more intense shoots without as many interruptions. You can shoot faster and longer without worrying about overheating.
