Hi, I'm sorry, I know there have been a million "what kind of camera should I buy" threads, but I need a hand and don't know exactly how to search within my parameters. Please assume I know nothing about photography. Wife bought a Kodax 4MP (LS743?)that works great...for everything except that I can't focus on the things I need to photograph like tool marks, serial numbers of guns, etc. I guess I need a manual focus? I don't think the "autofocus" feature can be overidden. From what I've seen, 3MP will take adequate resolution. I need input on the least expensive digital way to shoot close-ups. Guess I need something with a detachable flash, too, due to the tricky lighting of close up shots, and SIMPLE is good. I had a Pentax K1000 many moons ago, when dinosaurs roamed the earth, and it worked good. Many thanks.
