So even though Canon currently offers about twelve EOS cameras and about 70 EOS lenses, and fantastic wireless flashes and other accessories, the introduction of this one little $600 camera at the bottom of the EOS line in Asia only makes you conclude that Canon will not be a "viable platform". Because you are personally moving to a smaller format, you conclude that the entire EOS platform won't be "viable"?
No, that's not the only time Canon let users down. They just seem to stuck in the old sensor era and for several previously released products, I don't see any evidence that they will ever come up with a camera that has better sensor than last 2-3 generations, while the gap between them and the competition is widening - fast.
From current situation, I can envision that in 5 years time, other systems will have a FF sensor of 40MP no-AA sensor with 15-16 stops of DR and good ISO, while Canon still keeps cranking out the pathetic 18MP APS-C sensors. And I'm saying that with a high probability of it becoming the fact.
Sure, we can all fool ourselves to say that the 5D3 sensor is good enough. But for how long? How long can you fool yourself for?
It's again pathetic to see that the brilliant 24-70 II on 5D3 would only give you the worse quality photo as the Tammy on a D800E in terms of resolution only (forget about DR). Good glass being wasted.http://www.lensrentals.com/blog/2013/01/a-24-70mm-system-comparison
