Ok, I've seen an E-M1, new, for 650 euro. Wow. I decided that I wanted to keep the E-M10 as long as possible, I got it almost two years ago. But now these offers are tempting and I could sell the E-M10 to upgrade. Pro E-M1: - everything - in particular for me: better IBIS, weather sealing, PDAF (unlocking the 50-200 or the 150), better grip Pro E-M10 - smaller size - save some money Why not? Because it is almost the same tech, my pictures won't get any better (except the many blurry ones) and I do not really want to invest in big lenses because I got into m43 for smaller size. But when I consider the lenses too (12-40, 75-300, etc.) the size difference in the body seems like the last problem. Any thoughts?
