So I’ve bought some macro lenses of ebay for 11$ and they work great. I’m able to print 25 micron XY, without modyfying the lens. Also even 38 micron works better than by default, since you’re able to adjust focus ring to mid range resulting in more of the projection in focus. Also it’s possible to get resolution slightly lower than 100 micron but grt full plate in focus, useful for printing large objects.
There is some spherical aberration, but for my jewelry pieces it’s insignificant. However, for the next step I will create a photoshop action that counteracts aberration, then I can batch process all the images.
here’s the link to the lenses
