BCNranking published the top 10 best selling mirrorless interchangeable lens cameras in Japan for the period of January to September October, 2012. Some interesting points:
- Fujfilm is completely missing from the top 10 list.
- Canon is already at the #3 spot after they announced their first mirrorless camera in July, 2012.
- Nikon 1 J1 sales are better then I expected (ranked #6).
- In January 2012 sales of mirrorless camera made for 52.4% of the total cameras sold in Japan (in September 2012 this number dropped to around 45%):
