@jkallmeyer, Hey Jack, I hope you had peaceful holidays. I would like to see the picture taken with the smart phone lens. Can you upload it to the fossil list? I guess that the bad spherical aberration is the prize you would have to pay with such a setup. Can you make a photo from a grid to see how strong the spherical aberration is? That would help a lot. I would furthermore like to see a pic from the same grid with a Pro camera to verify. Can you do that? That would be great. Thank you!
All the best
Ronny
