The digital lens will undoubably cost more: it is newer and likely will have Auto focus and Image Stabilization.
An APS-C-specific lens *WILL* be smaller, with the emphasis on it being designed for the smaller sensor.
There is nothing "digital" about smaller lenses -- the size of the sensor will dictate the size of the glass.

Michael and Michael,Isn't the difference between older lenses and digital lenses the size of the lens? ie the digital lenses can be made smaller (and cheaper) since they only have to cover the area of the sensor be it C-APS size or 4/3 format size? Digital lenses will therefore be limited if one then goes to a full size 35mm sensor camera later on?RoyYour older analog "medium to long" lenses will work just fine with new digital sensors.
Use of wide-angle, analog lenses on modern digital camera "might" pose a problem, but then again, they might not. YMMV.In a message dated 1/4/2009 8:43:33 P.M. Eastern Standard Time, editor@xxxxxxxxxxxxxx writes:Your older analog "medium to long" lenses will work just fine with new digital sensors.
