That is where jargon and unmeasured terms are counterproductive. A bit like awarding whiskies a percentage rating: looks scientific, helps sell magazines, makes the writer look oh so brainy and expert, affects sales but doesn't have a whit to do with enjoying the product. >> I agree that second-hand expertise can be worse than worthless. As the old saying goes, a little knowledge is a dangerous thing. Moreover, the preachings of a false prophet are far more potentially damaging than a lack of guidance. OTOH, it has been wisely observed that it is the height of foolishness to disregard the valid experience of others who know whereof they speak. The challenge, of course, is to discriminate between the valid and the invalid, the true and the misleading. That is, among other reasons, why I admire the efforts of people like Erwin Puts, who make an earnest and very substantial effort to maintain not only scientific but intellectual integrity in their methods of research, analysis and reporting. I also have subscribed to Consumer Reports for many years. Decades ago, CR did a report on compact 35's which rated a certain Minolta lens as superior to the 40/2 Summicron. Specific testing and evaluation criteria were not stated, rendering the evaluation meaningless. However, I did not cancel my subscription in protest, nor did I unload my Leica equipment. After all, I wouldn't buy a window fan or toaster oven without reading CR first. Reports of empirical observations from trustworthy and authoritative sources are far and away the best practical alternative for information gathering in photography, as they have been since the beginnings of the art, or craft or science. That is why I participate in the LUG. By the way, the household Siamese has always been my test target for evaluating lenses. It's the laugh of the processing lab, and my wife begs me to stop disturbing his sleep. I can tell you pretty much exactly what Ted is talking about in terms of resolution of fine detail, at least at the other end of the equation. Strangely enough, the out of focus areas, at close range, can be revealing as well. On a more important subject, which single malts do you favor? Joe Sobel
