Originally posted by Winder Canon and Nikon both have issues right now with mirrorless. Canon wants to do everything in-house and they are trailing Sony in the technology needed to make a competitive mirrorless option. Canon is using 2 Digic 6 processors to do what Sony is doing with a single Bionz processor. Canon doesn't have the BSI or copper technology. The speed of the AF has a lot to do with processing power and how fast you can read information off of the sensor. Canon has fallen behind. Does Canon even have an R&D department anymore? They are like the Ricoh marketing department.
Not all lens adapters are cheap. You can drop $650 on a lens adapter with full electronic functionality. No different than a good teleconverter.
Nikon has been working on it and I think they have the same problems. They depend on 3rd party for just about everything and while Sony can build an integrated imaging pipeline in-house, Nikon is trying to piece together parts for different manufacturers.
My own feeling is that alliances are the way forward as the big three manoeuvre around each other. Nikon, for example, could look outside the imaging biz for software and processor expertise (Apple, Microsoft, Nvidia, etc). Nikon have a top-drawer branding to trade. The smaller outfits need to find a shelter in tie-ups with the bigger ones or they won't remain viable. Olympus has clearly already sussed that one. Fuji, Ricoh and co have it to look forward to. The software/processor challenge must be huge, and well beyond all save the largest companies, but it's the engine of these machines and their future, I guess. Nikon and Canon will change, though. They don't have a choice. Thus, more armchair strategy from the Summertown laundrette
