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 equipment.

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 Photoshop Dennis ------------------- What Dennis said. Feli
