I currently own a GH13 and have the ability now to trade with someone, my GH13 body and a Rollei lens for their HMC40. However, the HMC40 has a "nicked" front element, which shows up as a black area in footage until zoomed to about z30. Other than that, the HMC40 is in great condition with only about 40-50 hours on it. Should I keep my GH13 or do the trade? Post your opinions please. By the way, I also already own a T2i setup with a large amount of gear and a couple rigs.--------------------Thanks-Kyrankyranford@gmail.com
