Nice to have another film shooter! but why did you jump to an F5? Yes it offers many features, but it does not benefit a beginner to use such a camera imho, and the price point is also very high still. The N90s on the other hand is a very good choice for someone starting out, it offers pretty much all the pro features minus continuous speed and build robustness and a few other non-critical doodads. I would suggest grabbing the manual for your cameras either in print or online.
