RE: [Digital BW] Photodo MTF graphs

Hi Paul, The links have been broken for ages, and like you I assumed the image files were missing. Not so. I noticed very recently that it's just that the image references contain explicit IP address that are no longer valid, presumably because the servers were moved without the HTML being updated to match. If you right-click the "X" image and choose properties, you can see the URL contains the bad IP address. Copy/paste that into another browser window and replace the address with www.photodo.com and presto, you'll see the chart. For example, the link for the Canon 50/1.4 USM: http://193.14.88.41/pix/lens/mtf/CAEF5014.gif (broken) http://www.photodo.com/pix/lens/mtf/CAEF5014.gif (works fine) BTW, as you are probably aware, the lens pages take an age to load on most browsers because of the broken reference. You don't actually have to wait for the "X" placeholder to appear, you can just right-click the empty space after the results summary. Doing a Select All makes it easier to see where the placeholder is (generally just underneath the "D" of the Distortion result in the summary). HTH -= mike =-

Any idea as to what has happened to them or if they are available elsewhere? Those and the (other?) Swedish tests are about the most reliable I've even found, even if they seem to have stopped updating them long ago.
