First, my thanks to Carlo Guerrero and Pete Su for answering my question about AF Start button on the F100 so copletely. Your response was a great help. The fog has lifted (partially), but I have another question, one that has been bugging me from the start. I have figured most of the AF-L/AE-L button out, but I'm at the point where I need some confirmation or redirection. The manual (page 42) says that Focus Lock can be activated by pressing the AF-L/AE-L switch using ANY exposure method, including Matrix (regardless of exposure mode; i.e., Single or Continuous Servo. The functionality of this button becomes a little more restricted when reading the section on Auto Exposure Lock (page 54). The first paragraph says that exposure is locked by pressing the AF-L/AE-L button in any exposure mode other than Manual. So far so good. The manual goes on, however, to say that "Matrix metering is not recommended since the exposure cannot be properly locked" (???). (It would be nice if Nikon would have included an explanation of why this limitation exists and has nagged at me ever since I read the manual on the N90s.) So all this information seems to tell me that I have the following: Focus Lock with the AF-L/AE-L button in all exposure modes and metering systems. I have BOTH auto Exposure Lock and Focus Lock with the AF-L/AE-L button as long as I'm NOT in Matrix metering or Manual exposure mode. If this is not true, please, someone just shoot me. I guess the question never hit a nerve when the two functions were on separate buttons (Even though AE-L wasn't all that easy to use. Slider buttons have always been hard for me.). There is no question that this camera is a true master piece of engineering. A real achievement for Nikon. The camera has great "feel", slightly better than teh N90s. I only wish that I had availed myself of the opportunity to try on the F5, but my requirements never took me in that direction. I do see where Nikon could have done a much better job on the manual for the F100. It is 35 pages shorter than the manual for the N90s and its complexity begs for a more full/complete expalantion of key features such as Dynamic Focus with/without closest subject priority. I will be working my way through this issue for many weeks ahead. Perhaps "Moose" Peterson or someone else will penetrate the haze with a good tutorial based on their experience with this fine camera. Warren Kneis ([EMAIL PROTECTED]
