They will readily tell you when you call their in-house experts that work for this end, that they have perfected a camera that uses digital technoloogy and can accomodate their line of lenses without having to change your accessories.
Kudos to them! I admire their dedication to the end user. But, the Leica digital camera is not exchangeable with their film cameras a accessories. Sigma is primarily a lens manufacturer.
You just refuse to 'get it.' By saying nobody is redesigning SLR lenses for digital cameras is simply not true.
The lens designer I spoke with worked for Hasslebald (spelling?) and put lenses in satelites for digital, or electronic, download.
Jeff, you are simply not talking to camera dealers and manufacturers, but sitting at home spouting some sort of acrid skeptcism without research. Please, go to your local library and get, by interlibrary loan if necessary, Rudolph Kingslake's books and learn something about lens design besides some trade names. Gauss principles are different with electronic capture, for example. Bone up, buddy. :)

What I don't like about this post, is that Jeff infers manufacturers are fooling us. Good digital cameras have different lenses. Some manufacturers have designed their cameras to adapt to film lenses. The LF backs used by pros are made with such modifications.
Canon doesn't offer "digital lenses." Nikon doesn't offer "digital lenses." Sigma offers "digital lenses." That tells you exactly what is going on.
Nobody is redesigning SLR lenses for digital cameras, at least so far. Some companies are marketing their lenses as "digital lenses" in order to boost sales. It's really simple.
And I'm still wondering about the lens designer. Which cameras does he design lenses for?
