This allows you to actually focus on far away objects without hitting the stop, making it difficult to "home" in on proper focus. Some lenses, with special glass, focus beyond infinity to take care of temperature differential. Infinity will be different, depending upon the temperature of the lens. Direct hot sun vs freezing blizzard, etc. Jim At 02:48 PM 3/13/99 +0800, you wrote: >Hello everyone, > >My infinity question is refering to R8 with tele lens.
