[Leica] Software lens correction

[r.s.taylor at comcast.net (Richard Taylor)]

Actually, you're quoting me here and I agree with you completely.   
Technology advances and the best and most successful cameras should  
take as much advantage of new developments as they can.  We will  
almost certainly benefit from it.

Regards,

Dick
