(Annoyingly, this log broke when I tried to save a draft so I have to write it all over again.)
I got this lens a while ago (March 2) and I finally got around to taking some images. I also decided to take more images of the 60mm lens but I didn't keep track of when I stopped taking pics of the 37mm lens and when I started taking pictures of the 60mm one. Also, here's the fresnel lens images to compare, and the fresnels sure look lower quality in comparison
Most of these images have been taken with 2 lenses stacked to emphasise any optical imperfections.
I think these ones are the 60mm lens
