We talked with Mathew Frazer from Panasonic about overheating of DSLRs and mirrorless cameras and how Panasonic deals with heat dissipation in LUMIX cameras. Digital cameras generate heat. With resolutions, framerates, and bitrates getting constantly higher, the image processing components need to perform faster. Just like with computer components, high performance results in heat buildup. Professional cameras usually deal with the accumulated heat by incorporating one or more active fans for better air circulation. Smaller, weather-sealed mirrorless and DSLR cameras represent quite a challenge when it comes to heat management. Recently, the topic of camera overheating got often discussed after the new Canon EOS R5 and R6 cameras got introduced. At CineD we decided to start a series of discussions about camera overheating directly with camera manufacturers – starting with Panasonic. Cameras and Overheating – Panasonic Our interview partner was Mathew Frazer from Panasonic US. He told us how the company tackles heat management in LUMIX cameras. Mathew mentioned the dangers of too much heat in a camera. First of all, the image can show shading or degradation when the internals get too hot. The issue also can be that a camera overheats and shuts down without wrapping up the recorded file. In some cases, the user might end up losing the file altogether. According to Mathew, Panasonic makes sure that this never happens with LUMIX cameras. Panasonic LUMIX S1H.
