The gist of my question is this: How long before Canon releases a camera with the sensor technology it seems Sony and Nikon currently possess? The sample images I've seen so far from the 5DIII and D800 have me underwhelmed with Canon's offering, especially at the price. My initial thought was to sell my lenses (a few L primes, the 50 1.4 and 28 1.
and move to Nikon. I want to go FF, but I want great low-light and superb focus. If I can't get both, I might as well go for the superior resolution of the D800. There doesn't seem to be anything in the 5DIII for me other than existing lenses and familiar UI.
The alternative would be to invest in glass and wait for Canon to start using Sony sensors. I could get a 70-200 2.8 IS II and the new 24-70 2.8 II for five grand or so and wait a few years for the 5DV, the 3D, or some other mystical unicorn.
I have no problem waiting a few years. I'm happy with my T2i and current glass, but I really want to add a FF at some point. Is there any reason to suspect Canon will go elsewhere for better sensor tech (and WB tech while they're at it?).
This is not a trolling post, btw. I've been eagerly awaiting the 5DIII for years and hovered over the pre-order button dozens of times. I have the money to spend. I'm just flabbergasted that they allowed the most important/anticipated product release in the companies' digital history to fall flat on its face like this. (My opinion of course and based on the handful of images released thus far).
