Here is another interesting product that was on display at the 2025 CP+ show in Japan - the ZNONZ II lens captures an image by using diffracted light:

ZNONZⅠ makes an interesting “lens” that doesn’t use any lenses because it captures an image using diffracted light. The founder, Tatsuoki Takeda became tired of clinically perfect photography and decided to do something new with zone plate photography, which is a style of pinhole photography. The lens mount is a universal Leica M mount, and there are two types of lenses “Type I uses an amplitude type zone plate, while Type II uses a phase type zone plate.” They both are turret type that can produce four different images that is operated by the dial on the side that is similar to a wristwatch dial, but it to keep it from being misaligned with the optical access a geneva mechanism was developed for a mechanical feel.

Additional informtion on the lens is available here and here:
