Great video. Leica’s got a nice one too. Always surprising to see which steps aren’t automated.

Haven’t looked at the video, but generally speaking only cheaper grade lens elements are machine-polished. That’s why they’re cheap. Machine-polishing does not have enough randomness to achieve a top grade lens. Counter-intuitive, but it’s true. Manual polishing combined with the correct process gives the best results.

Yes this does sound very counter-intuitive and would seem to require some substantiation. Certainly many machines work on high to true randomness applications, so there would seem to be nothing technically impossible here.

I’d be keen to know if there is though.

Very nice. This reminded me of the Leica lenses video as well.

My husband (wedding photographer) just showed me Leica’s video. It’s incredible. Either way, it IS refreshing to see the human touch on something so mechanical. Great share.
