Apologies - this is pretty much a cross post from DPreview but the numbers are quite interesting so I thought you would like to see them. BCNranking has released the market share data for mirrorless cameras in 2013. A bit early you say? Yes well the data only goes up to the 23rd December. BCNranking is pretty accurate as it covers over 50% of retail sales. Note this is data for Japan only - obviously the US data will be different. Amongst the individual camera market share... 1) The big winners are Nex 5R (well it came first), EOS-M came second and up from 2% last year 2) The big losers are Nikon J1 - winner last yea, Panasonic GF3/5 combined sales 13.5% last year 3) Yes the Olympus EPL and EPM are insanely popular but then again they were insanely popular in 2012 as well. The market share figures for the individual brands Olympus 29.1 Sony 26.1 Panasonic 14.2 Ricoh 9.8 Nikon 9.34 Canon 9.25 By a process of elimination that places Fuji at 1.9% (BCNranking doesnt compile numbers for Leica and Samsung). It should be noted that the Fuji X100 series is not included in mirrorless ILCs. I only have the market share in 2012 for the top 3 brands at hand. Olympus is slightly down from 29.8% in 2012 but retains its leadership position. The big winner is Sony up from 20.1% to 26.1% and the big loser is Panasonic a distant third at 14.2% compared to 23.3% last year. From memory the big loser amongst the smaller manufacturers is Nikon down from 15% and the big winner is Canon up from 2%. M43's market share is down from 53.8% in 2012 to 43.3%, reflecting the rise of Sony and fall of Panasonic - Panasonic was market leader 3 years ago. Really nothing terribly surprising in the numbers. Perhaps what is interesting is what is not really in the numbers. The E-M5 is down in 17th but it only came 11th last year. There is no sign of the GH3 although no GH2/3 last year too. No E-P5 - goes to show what happens if you produce a good camera and then totally misprice it.
