In Year 2009, I was introduced to the m4/3 format cameras like the Panasonic GF1. After using it, my "myth" mindset towards smaller sensor size like the 4/3 format which was introduced by Olympus are inferior to APC size or full frame size sensor was gone.

I realized smaller sensor cameras have their advantages. The lens with larger aperture can be relatively smaller in size and the ultimate advantage of Olympus is that their out-of-camera Jpeg pictures are really rich in colors and sharpness compared to Canon DSLR.

End of the day, which ever brand we choose, we need to know the limitation and work towards it to create a better photo.
