  • To prevent overheating, stop shooting for a while and place the camera in a cool, well-ventilated area, carry a mini umbrella, use a fan, keep the battery door and memory card slot open, cover the camera with a towel or use cold gel packs, use faster memory cards, and use external batteries or a spare camera for long shoots.
  • Some mirrorless cameras, such as Panasonic Lumix DMC-G85, Panasonic Lumix DMC-GX85, and Panasonic Lumix GH4, are less prone to overheating and can shoot for extended hours without any complaints of overheating.
  • Proper prevention methods and investing in the right mirrorless camera can save your camera from overheating and extend its lifespan.

Why do mirrorless cameras overheat?

Shooting under direct sunlight. But, this is not the only cause. The other reasons can be continuous shooting, lack of ventilation, slow memory cards and sometimes even weak battery life. The size of a mirrorless camera can also be one of the reasons for overheating; a compact size does not allow the heat to release or air to circulate within the circuits.

Why and how can we prevent mirrorless cameras from overheating?

Some mirrorless cameras such as the Canon EOS R6 have been reported to shut down while shooting because of the overheating issue and taking quite some time to restart. Prolonged exposure to heat can damage the image sensors and lenses of the camera. You wouldn’t want that to happen with our cameras now, would we? Here are some tips that you can practice to avoid further damage to your camera due to overheating.

  • The first thing that you can do is stop your shooting for a while if possible and place your camera in a cool, well-ventilated area with proper airflow.
  • If you know that stopping the shoot will not be possible, then carrying a mini umbrella would help in cutting out the sun’s rays and provide the shade needed for the camera to remain cool.
  • Pointing a fan at your camera will also help in speeding up the cooling process.
  • Keeping the battery door and memory card slot open is also proven to be an effective way to prevent the insides of the camera from overheating.

Note: The opened battery door and memory card slot will not affect your shooting or damage the battery or your memory card.

  • Cover your camera with a towel to help control its temperature. You can also use cold gel packs along with a towel – as long as the packs don’t get wet, they are a great defender against the heat.
  • Use faster memory cards, so that your camera won’t have to work twice as hard and the production of the internal heat would be minimal.
  • Since batteries get hot a lot faster than any other part of a camera, use external batteries.
  • If you’re a professional photographer or a videographer, having a spare camera would be useful in case the above methods do not work.
  • After finishing the shoot, be sure to put the camera back in the bag – as cameras can get heated even when they are not used.
