InfiRay Zoom ZH38 review in pair with Pulsar Helion 2 XP50 PRO

I finally managed to take Zoom ZH38 thermal imager for review. A lot is now said about the unit on the market and I was greatly interested in how zoom lens will perform against normal lens without zoom. As one of the best samples of thermal imagers with non-zoomable lens and more or less similar field of view I decided to take Helion 2 XP50 PRO. I have to say that ZH38 has two positions of focus (19mm and 38 mm), but comparison was only at higher magnification (38mm) to match Helion's magnification and field of view. Also I should mention that Helion 2 XP50 PRO is slightly higher in price. Zoom ZH38 is a good unit for the money and performs well, however there are some things that you will not see without comparison. The findings about Zoom ZH38 are in the video.
