Beyond an RX2?
In reply to maxuci, 5 months ago

A fixed-prime RX2 is the obvious proof-of-concept for this technology. I think I read that a matching lens has already been patented. But can this technology be generalized to multiple prime focal lengths, zooms, and ILC?

Focusing even a prime lens is a matter of making slight changes in focal length, no? Does this imply that zooms as well as primes could be designed for a curved sensor?

It also suggests that third parties like Sigma and Tokina would be reluctant to offer lenses for such a specialized lens mount at least until sales reached a certain threshold. So, if Sony were to release, for example, an ILC with curved FF sensor, the only lenses you would be able to use on it in the near to mid terms would be the ones Sony released over time. And surely Sony is already over-extended in the area of lens design and production.

Or could there be an adaptor to allow use of traditional lenses? Even though the curved sensor advantage would be lost, at least the camera could then be used more generally.

Also, the lens has to be specifically designed for the sensor, so, there will be limited application outside of fixed lens cameras.

I don't see why Sony has to change the lens design!

The way I understand it, the curvature only helps with straightening the light entering single pixels far removed from the centre.

Current leneses are designed to focus on a plane. Lenses for this need to focus on the spherical surface
