"Over the last few years, we’ve seen how Sony has made some pretty huge gains in the photography industry. This is especially true for the mirrorless market and plenty of photographers have switched from DSLR cameras to Sony mirrorless cameras. Even still, I predict that once Canon releases its mirrorless cameras, it will eventually dominate that industry too.
I’m assuming some of you may have some snarky (and more than likely humorous) comment about how Canon might if it actually released a mirrorless camera. We can comfortably allay those thoughts because Canon has stated it will be focusing on mirrorless, even if that means its DSLR sales are cannibalized. Many of the rumors are suggesting that Canon will be releasing a mirrorless full-frame camera within the next few months and once it does, mirrorless will officially be on the road to becoming mainstream"
Man
Canon explain it
