While every machine is different, if a lens is transmitting 60% contrast at the 30 or 40 cycle line out 15mm wide open then you have a really good lens. If every manufacturer would just publish MTF charts for real production lenses then most of the nonsense about my lens is better than your lens houey would stop. 0.02 Don dorysrus@mindspring.com -----Original Message----- From: lug-bounces+dorysrus=mindspring.com@leica-users.org [mailto:lug-bounces+dorysrus=mindspring.com@leica-users.org] On Behalf Of Jeffery Smith Sent: Saturday, January 01, 2005 8:33 PM To: Leica Users Group Subject: Re: [Leica] Intro It's really a shame that there is not accepted means of evaluating lenses using a meaningful barometer. If someone would get a 36x24mm 20 megapixel rangefinder, stick each of the Leica, Voightlander, Rollei, and Konica M lenses on it, shoot at a decent target at each f-stop, then at least we could have a gut level feeling for resolution, contrast, distortion, etc. Isn't there one rich camera buff out there who will do that for us? Please ? ;-) _______________________________________________ Leica Users Group. See http://leica-users.org/mailman/listinfo/lug for more information
