Hey guys, first post here.. I'm new to m4/3 cameras and came from simple P&S. I already had my E-PL1 shipped to my address and im just waiting for it to arrive. I was just wondering if I also need to get the Panny 20mm f1.7. I'm not a hardcore photographer and most of my pictures are for personal use. I just thought about upgrading to something different and maybe improving my personal pictures. This can range from simple walking around to big events. I've been reading around and people make it sound like it's "a must" to get that lens for the EPL. So, is it something an E-PL1 user can't live without? I mean how much of an improvement does it offer compared to the kit lens?
