I have read through allot of post in this thread stating that it will take a long time, I’m not so sure about that. Sony has already taken the lead role in Japan on the FF market holding over 38% of market shares, it’s not the only market where that has happened. Yes dSLR is still the most sold on a global scale, but it’s dropping fast and it won’t take 10 years before Mirrorless FF cameras will be the dominant force, in fact with annual growth pr. Year then a very realistic scenario is closer to 5 years.
Sony has close to 25% global market shares, making them bigger than Nikon. And while the latter sees sales drop on a rapid scale, Sony is on the rise, at the time it very much look like they will be the biggest brand if this trend continues the next few years. Personally a 5 year horizon is realistic for Mirrorless to be the dominant force in gross unit sales. Especially as Canon and Nikon has entered the development and market.
However the overall camera market is suffering badly, Sony is one of the few sparks in the dark, and only Mirrorless somwhat holds its sales. This is why dSLR will die eventually, these products simply do not hold sales, Nikon had a drop of 26% in unit sales on the APS-C market, 14% on the FF market and 25% on fixed lens market. Canon only had a somewhat positive numbers on unit sales on the FF market, largely thanks to Mirrorless.
Last but not least Mirrorless FF encounter for approximately 60% of the Japanese FF market. This clearly indicate where it will end.
