I'm going to Japan for the first time at the end of the month and decided to upgrade from my OM-1 to a well-loved OM-4. I've been using my 1 for about three or four years now and I think I've gotten quite good at getting the shots I want but I've never used something with fancier features like spot-metering, though I figure wort case scenario I can put it in manual mode and use it like my OM-1. I'll have a week and a half before my trip to play around the the 4, any advice on how to get the best of my new* camera?
