Nice camera, the F100. I've one and it's not nearly as tough as you'd think to figure out. First off, forget all the other books, etc. writen by the so-called experts. They're really good devices designed to separate you from your money and don't offer anything that isn't covered in the owner's manual. You don't need to use AF lenses either. I regularly use mine with old manual focus lenses, and it works just fine thank you.
