Bill, If you had the camera in a focus priority mode such as the default "S" autofocus mode, and it is too dark for the camera to focus, or verify focus, It WILL NOT fire. You have two options at this point. 1.) switch to a release priority mode such as the default "C" autofocus mode, or change the "S" mode to release priority via CSM# 2. 2.) go to manual focus. Please don't take the following comments the wrong way they truly are intended to be constructive. You've sunk a heap of $$$ into your system. Sit down w/ your instruction manual and perform every function in there. As you are comfortable with all of the options learn where all the buttons are, so well that you could find them in the total darkness. I'm not sure in what capacity your using your F5, But as for me being a wedding/event photographer, I often find myself in situations where I cannot see the buttons on the camera. Knowing where they are has saved me many a time. You also may want to get in the habit of keeping a Mini-MagLite or equivalent on you when you expect dark situations, there great when you can't see to load film. Hope you come to love your new tool as I have, Wayne Jordan Jordan's Photography Trussville, AL P.S. call me if you decide to toss it, I'd love to shoot you swimming after it when you came to your senses!!! :-) ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
