Hi, I'm trying to take pictures of birds with my E-PL1. I'm using the wild life macro and notice that many times when the camera goes to auto focus it seems to select everything but the bird. Such as leave's, branches etc. I know part of the problem is distance and I need to get a lens with a better zoom which I'm working on. But figured I'd ask for any tricks or tips. I have tried the zoom button with mixed results. Thanks.
