refocusing the lens on an action camera with a narrower field of view lens (90 degree). Still not a perfect macro but a good close-up can be achieved: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rBWDJaA43AE.html
@@MatthiasLebo It has some limitations and the DOF is surprisingly narrow despite the small sensor. The focus is fixed, so it cannot follow the subject, but the camera is below 200 Euro, so it's not that bad
Thanks for having me! I didn't give my top secret top, but I will now.... The secret is to film a critter that is so cool, that if its bad quality video, no one notices.
Usually I dial down the power unless I want to take some more special macro shots (black background) in which case I use a snoot light like the Backscatter MW4300.
I wouldn't use a magnifying glass. That seems awfully complicated and I'm pretty sure the results are not going to be the same. I would use one like this, depending on your GoPro model: amzn.to/3iJ05ER
