I never really looked into MFT(micro four thirds) cameras before and didn't really take them seriously. I already own 3 full-frame cameras and if I'm ever going to get into a new kind of camera system, it was probably gonna be medium format, something like Hasselblad H5D with much bigger sensor, not smaller.
I don't know about you, but I ALWAYS run into "Damn, I wish I had my camera with me right now" kind of situation almost every day. They say 'The best camera is the one you have with you', and I just could't agree more. Sure, I could just use my iPhone, but the quality isn't just satisfying.
Due to smaller sensor size, MFT cameras produce a lot less bokeh than the full-frames. Some people might find it as a disadvantage, but I think it creates a great opportunity to challenge yourself to capture the moment solely by your composition skill without depending on your fast prime lenses to do your work for you.
