>We seldom talk about 3D printing lenses because most techniques can’t possibly produce transparent parts of optical quality. However, you can 3D print something like a lens, as [Luke Edwin] demonstrates, and get all kinds of crazy pictures out of it. [Luke’s] lens isn’t really a lens, per se. There’s no transparent optical medium being used to bend light, here. Instead, he’s printed a very fine grid in a cylindrical form factor, stuck it on a lens mount, and put that on the front of a camera.

The japs made good glass, and better than most, close to German Quality, but only close. They are a proud honorable group of zipper heads.

Yes. Hoya was good quality for a good price. I have no idea how they stack up now, just that my eyeglasses have Hoya lenses.
