I had pretty much decided to get the 12-50 with my OM-D but is it really worth the $300? I have an E-PL1 with the 14-42 kit lens that originally came with it. It's a pretty capable lens and I only use it about 15% of the time -- my 20/1.7 stays on my camera most of the time. I know the 12-50 has the power zoom which is handy for shooting video but from a picture quality standpoint, it is that much better than the 14-42 that I already have? $300 better???
