Hello! I'm deeply into configuring my new E-PL5, and have a few questions. 1. What are the function buttons on this camera? There are the letters "fn" next to the "checkerboard" button and the "magnifier." Does that mean that both of these can be programed as a function? 2. I want to program one of the above buttons for spot metering. Is this possible, and if so, how? 3. Is there a way to see the effects of IS in the LCD/viewfinder? That apparently can be done on the EM-5, but I don't see it on the E-PL5. So far, I'm really liking this camera, after 8 years with a Canon 10D. There are a few issues to be ironed out, but I'm looking at the little (a bit too little is one) Oly as a paradigm shift for me. Thanks!
