Multilayer sensor from Sony ensures smaller lenses

Finally, tiny lenses can have a short registry distance too! The only thing that was missing in the Sony MILC line: tiny pancakes to match the tiny camera bodies.

Innovative Sony multilayer sensor patent shows how to get rid of corner issues.

QuoteQuote:
The short E-mount flange distance has one “drawback”. Lenses have to be larger to correct the incident angle at the corner which usually causes heavy color shifting, huge vignetting and loss of sharpness. That’s why Voigtlander redesigned the Heliar 15mm III lens (here on eBay). And the new design makes the new lenses twice as big as the predecessor.
The fact that this is a multilayer non-bayer sensor seems to be of secondary importance. I find it the most interesting part though.

I also don't know how this would work with their IBIS? The lens would float together with the sensor and thus not be correcting in the right places.

So instead of adding the correction to the lens, making it bigger, you add the correction to the sensor? That way the lenses will need a smaller correction. Sounds interesting, but it might be difficult for third parties or adapted lenses. Definitely an interesting patent, though. Thanks for sharing.

It sounds like this is useful for fixed lens cameras.

Yes, cause it will have negative impact on long tele lenses (on which light rays are quasi parallels cause of the long focal)
