Interchangeable Lens Camera Marketshare for 2012 (Japan)
Canon 28.6%
Nikon 25%
Olympus 14.3%
Sony 13.3%
Panasonic 11.3%
An interesting note about Canon, if you remove the lowend of the DSLR market (Rebels, D3xxx/D5xxx), Canon’s marketshare increases. I imagine the 5D Mark III plays a big part in that, as well as the EOS-1D X.
Canon’s performance in the mirrorless segment cannot be properly measured until the 2013 numbers come in. For 2012, they sat at 2.1% marketshare.
