I have a very small bag I've been using for my EPM1 and the kit lens. It holds that and an extra battery and that's about it. That is what I wanted. But I just bought the Oly 40-150 and my tiny bag won't hold even the camera with that lens mounted. What I want is a small bag just big enough to hold my camera with either the kit or the 40-150 lens and the other lens and a battery. Unfortunately, it is hard to tell what will work or what will be bigger than I want by looking online. Do any of you have any recommendations for a bag that size? Thanks!
