@filipc, thanks for clarifying that. I hadn’t heard of action cams having trouble with heat until some pretty high temps, like 50C+.
Like you said, it’s a common problem for smartphones. I’ve had decent results with the Garmin Virb Elite. For anyone with just a camera, you may still be able to nab one for @$150.
Think of these things as tools. Multi function tools are great but they have their drawbacks. Having a tool that specializes in one thing, an action camera, helps a ton.
