## Customer Reviews

### ⭐⭐⭐⭐⭐ Flir E4 Macro Lens
*by C***S on October 28, 2020*

- Used the 20mm 4" on my Flir E4 (upgraded E8 hack) for Micro Electronic repair.- Made a huge difference in close up resolution!- The 3D printed bracket covers up the MSX camera image. So all you get is thermal only. But image is clear enough to not need MSX overlay (I think. Time will tell).- If I had to do again. I would order a larger diameter, to get rid of the circle effect in the image. See photos. But it's really not that bad, with the 20mm.- In short. Major upgrade!
