Many of these opinions and impressions are instructive and forces one to contemplate established views and personal opinions. Still there is one potentially unsettling strand in all this. All information presented on the Lug is of equal democratic value. And so it should be. No room for gurus or authorities here. As Orwell noted in his Animal Farm: all animals are equal, but some animals are more equal than others", so not everything we refer to (magazine articles, books, 'some authoritive but anonymous source', personal observations) has equal stuture or stands the test of time and/or careful analysis. Our collective knowledge and wisdom will only progress as long and in so far as we are willing to neglect or disregard 90% or more of what we know, like to know, cherish as fact or have known or be informed about in the past. Assume that an optical designer in front of Leica's computers would use optical formulae from the thirties, however valuable they might have been or would disregard modern optical theory because somebody values the quality of old lenses. To be specific: maybe we Luggers shoud read less about Leica, would dump all of our folders, magazine articles and books and start to disbelieve and question everything ever written or stated about Leica and related topics. On image evaluation the bottom line is user acceptability: when an image appears to be pleasing or acceptable to a viewer and has sufficient detail to convey the intended message, the result is OK. We might like to have different parameters or more precise and quantitative measurements. Still the only judge is our own eye. I am always surprised by the large amount of questions about the relative and absolute performance of a lens and the many differing or even conflicting answers. The recent small thread about the D3200 development figures is a case in point. Why believe whatever is said and then following the advive of whomever sems most convincing. A simple test (one film and a sequence of exposures) in a standard developer is all that is needed for one's own judgment: no need to study magazines or go for numerous advices. (Note that the D3200 figures go from 6 to 15 minutes). Do it yourself would be my sincere recommendation. Some benchmark figures may help to get a base line (may I humbly point to my reports): the rest is private experiment and judge ones own judgement. My Xmas thoughts, based on extensive discussions with my brother. Erwin
