Just ordered a 2nd hand PANASONIC 14-140MM 4-5.8 (old version) via scamazon. I am pretty new this whole lens thingy and dipping my toes in by using a Yi M1. The PANASONIC LUMIX G VARIO LENS, 14-140MM, F3.5-5.6 is a little to costly right now, but If I decide to buy a really good body this would prolly the route I think I would go (for my uses).
