Re: New generation of "digital" lenses: only a commercial strategy?

Well, so guys.. one more reason (I already was oriented in this direction).. to wait for CCDs or CMOS with 1 : 1 correspondence with 35mm format

In this case (1:1 coverage) should a good old generation lens perform like a new "digital" lens ?

better for that situation.

David is correct. The problem is with wide angle lenses. The light
rays at the edges of the image strike the sensor (CCD or CMOS) at
an extreme angle. The currently available 14mm lens for 35mm film
cameras is a 21 for digital. Those of us who shoot film have been
spoiled by zooms down to 17mm. Its not currently possible to design
a non-fisheye lens wider than than the 14mm. But something like a
10mm lens could be designed if it only had to service the pro
digital SLR.
