In this case I'm saying m4/3s is the bigger sensor over the 1/1.7" type sensors that are in Canon s110 or Nikon P7700. So, you're on vacation and realize you forgot all your m4/3s gear except what is already on it, which is the crappy 15mm f8 body cap. You also have your your Olympus XZ-2 or Panasonic LX7 with you so you just opt to use that. But, that's your wife's camera so you're forced to use m4/3s. Sure, you lose 4 stops being stuck at f8 but there's still light outside and ISO800 is no problem so no big deal. Anyway, I've been in this situation. What is it about the larger m4/3s sensor that makes the images so much better; even with m4/3's worst lens. It's the color, I believe; but why?
