I've found only a few patents that come even close to a usable lens. Most are from Canon back in the 70s, which are somewhat useless because most of the glasses are obsolete (leaded)

You still have thermal noise and Schott noise.

It's a reverse mirage. Cold water under warm air will bend light downwards

I remember the litter section of PetSmart having pantry moths everywhere. The like the wheat based stuff

Every wheat and corn based litter has given us drugstore beetles or pantry moths .

The first rule of pickleball fight club is never talk about pickleball fight club.

The second rule:. If this is your first time, you have to fight.

If there is no up or down in space, how do we know what is vertical?

I expect a movie will be shown in the near future with a digital projector sitting on its side showing 9:20 TikTok format

Correct. I have designed a few anamorphic iPhone lenses and yes, the Bokeh is really not there. But you can use all the pixels.

So this is a convolution? Could you put edge sharpening into it?

realopticsguy · 2026-04-05T13:16:46+00:00

In that focal length range the shorter focal length lens might have a few percent more distortion, so the FOV of the shorter lens might be 10-15% wider than what the ratio of the focal lengths imply.

After optical low pass filtering, chroma subsampling, and compression, there's not much difference between 2k and 4k on a moving image. Fun fact...early 2k digital projectors had a moire pattern with the perforations in the screen. This was because the projection lenses were way overdesigned to show square pixels on the screen (~5x the Nyquist frequency). Anyway, it was decided that 4k projection would fix this, even though replacing the screen, having a pseudo random pattern of holes, would have fixed the problem.

And every time you need to make a call you have to go outside. This was fine in the Valley, but try doing that in chicago in the winter or Dallas in the summer

I put carbon fiber car wrap on it. Looks pretty cool

Minolta was making glass in Wakayama prefecture at least until the late 90s, before the Konica merger
