So you're saying that Canon wouldn't want bring out a new sensor to try and spur sales growth across their lineup?
What - you mean, follow Nikon's lead?
Not doing them much good as far as actual sales of cameras is concerned, is it?
You still don't get it. Canon is selling more cameras than Nikon and Sony right now, with its existing sensors: because most photographers don't care about, or need, the niche benefits that "superior" low ISO DR provide.
So this "improvement" would be an irrelevance to the majority, and will do bugger all to "spur sales growth".
So in order to keep sales up..
- Nikon churns through models
- Sony reinvents the camera
- Canon does nothing except take consolation in knowing it sells more units than Nikon/Sony and just watches sales decline?
Irrespective of whether or not Nikon/Sony have better or worse technology their activity keeps their models current and in the mind of consumers. Shorter product life cycles means that they can react quicker too.
Whether people like it or not, based on past releases, it is safe to expect the 5D4 out next year and not 2016/2017.
