One of the Mirrorless system cameras main advantage is the size reduction compared to DSLR cameras. And according to top sources at CanonWatch (Click here) Canon is about to change that by announcing the smallest DSLR camera ever made. And it almost sounds like that is the way Canon want to go to compete against the various MFT or NEX cameras. Their EOS-M camera was not able to gain any noticeable favour from the market.
We hope to see some pics of the camera soon. I am sure it will be smaller than a GH3 and maybe even smaller than an E-M5!
