Not really. That is a different issue, and applies for smaller sensors. You *really* want to use a full frame sensor...but, as stated, when used with a full frame digital sensor, the light rays, for even normal lenses, just like with real wide angle lenses, cause "vignetting". > I acknowledge that my knowledge of optics and optical issues is > more than a > little limited.

IMO, it's not worth it if you can't make it full frame. They'd be better off doing something with the R "body". Austin - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
