Come on, guys, digital imaging is in its infancy. If you think the current 
state of the art is anything like what we will see in 20 years then you are 
not using your imaginations :-)  Digital imaging is growing much faster than 
film-based imaging ever did;  looking at this year's products is extremely 
short-sighted in this context.

Software corrections of optical aberations are already being done, as Dennis 
said, in the computer (PhotoShop plugins). It may be a longer time before 
the cameras do the fixes, but it will happen. The lens used to make the 
image, along with the focal length, distances, aperture, etc. are all easily 
recorded, and the image converter can use this information, along with 
profiles of the lenses, to adjust field curvature, barrel distortion, etc. 
This has been discussed by several leading camera manufacturers who realize 
that the game has change - I'm not making this stuff up! ;-)

My point was simply that the future of optical design for digital imaging 
purposes will, in all likelihood, require in depth knowledge of software 
systems in addition to refractive indices and the like. Leica will have to 
learn new skills or become irrelevant. I think they can do it, don't get me 
wrong there - I give the Leica engineers a lot of credit. They just need a 
new owner, one that understands what it means to design and make imaging

I have not heard of anyone correcting optical aberrations such as chromatic
aberration, astigmatism, curvature of field. I would think the digital
information needed to make corrections well exceeds the capture ability of
todays ~13 megapixel sensors.

Certainly barrel and pincushion and vignetting, these are already done in


What Dennis said.
