I didn’t say that. The M line ‘competed’ with Canon’s APS-C DSLRs, especially the xxxD series. In fact, it still does (and in Japan last month, the Kiss X10/250D was the best-selling ILC, and the Kiss M/M50 and their MkII versions were close behind). Canon has no problem with that, why would they suddenly be afraid of FF DSLRs ‘competing’ with FF MILCs?
I’m putting ‘competing’ in quotes because it’s really not competition. Whether Canon sells a DSLR or an MILC to a customer, it’s a sale. You may want to brush up on your business acumen.
Sure. That’s why Canon has given the RF lenses advantages over their EF counterparts in many cases. A 24-70/2.8 with IS. A 28-70 f/2. A 15-35/2.8 with IS instead of a 16-35/2.8 without, and now a 14-35/4 IS instead of a 16-35/4 IS. Et cetera.
But if a 5DIV user wants to buy a 16-35/2.8 III or a 5DIII user wants a 5DIV, Canon will happily sell them.
So far this year, the MILC : DSLR ratio has been 56:44. Last year, it was 55:45. Barely a majority for mirrorless. I really don’t understand why people seem to think Canon would just abandon nearly half of their market.
