I literally just barely finished switching all my Canon stuff to the m43 not 1 month ago. Bought the P15, O25, 045, 060, 9mm BCL and a couple slower zooms. My pictures are turning out fantastic. I like all of the lenses. So why am I already comparing different lenses and contemplating lens swaps? Maybe my 15 and 25mm overlap too much. Maybe I should get the 45mm macro and 75mm f1.8 instead. Should I have got the 17mm f1.8 instead of the 15/25 pair. 12/25 instead of 15/25? Should I sell it all and just go with Leica 15 and 42.5? I'm ill, I tell you.
