Hmmm .... another comment that has slipped through my filter. OK, I can't let this pass as, iirc, JCO made this comment several times:

I don't understand what the "time difference" has to do with anything. This isn't like audio testing where a quick A-B comparison may be helpful. Here we can use two lenses, take a picture with each one, or several pictures, and in a matter of seconds put them up side-by-side to compare the results. This is photography, so actually looking at the results is a very simple thing, and whether we look at those results immediately or a year later, the images will be the same. Further, the results can be viewed at any magnification - up to 1600% in Photoshop and to almost an unlimited degree of enlargement when making prints, so it's very easy to see just how well each lens focused on a given subject. Would you please take a moment to explain why changing prime lenses and the time difference you mention should be considered a factor?
