I current own a E-PL2 and a GF2 body. Lenses wise I have the two kit lens Oly 14-42, 40-150 and the Sigma 19mm 2.8. This is the system I am using right now. I recently used my friend’s GH3 and panny 35-100 2.8 combo for an event. I loved the camera and the quality of the images I was able to get out of it. Obviously this setup is a lot more expensive than what I currently have. There is no question that a 35-100 2.8 will give me better IQ everything else being equal. If I do spend the money on a better lens like a 12-35 2.8 and put it on my GF2 rather than a GH3, am I really getting that much more things out of the GH3 that I am not getting out of a GF2? I am not talking about controls, FPS, focusing system. I am just talking solely on IQ of images from normal situations (not like taking pics of car at Indy 500 for example). More important, the colors and WB might be more accurate on the newer body but isn’t this something that can be adjusted in LR4 if I spend a couple of extra mins to edit it instead of spending $1,200 to buy a new body? I do understand the concept of “you can’t edit something that isn’t there” like sharpness and stuff but is it really that different when the sensor size is the same on a GF2 and a GH3? What do you guys think or am I stupid?
