Hi, guys. I just got a 14-140 II and I'm trying it out on my EM-5. I've gone back and forth using the lens OIS and then the camera IBIS to shoot a detailed wall map and I can't say for sure if one method is superior to the other. I get hits and misses either way. The only sure thing is that you can't have them both on, they seem to fight each other. I've searched the forums and heard some people say the focal length you're shooting determines what system is best. Panasonic also claims that their newer Power OIS beats the old Mega OIS by 2 stops. What do you guys think, use the IBIS or the lens OIS?
