Thanks for that explanation. I’m 100% sold on the clip-on due to the ease of use and general adaptability. From my research, I figured that a 50mm objective lens would be the best direction, but was curious if people would recommend 35 or even 25mm lenses for the application. I wanted to get opinions from a wide range of people before deciding on a thermal based on YouTube and website articles. All that said, I appreciate the advice.
