I fell for the hype and bought a Nikon D800. It was a nice camera, but, the 24-70mm G. Nikon's top of the line lens was a disaster. Even now, only a very few lenses can get the best of the D800, and, they are third party lenses, or prime lenses.
Since the big bucks is investments in lenses, I decided that paying more for less was not really the way to go.
I likely would never consider getting a nother high mp body unless it actually delivers enough more when coupled with a lens..
I wasn't talking about a D800 or high MP FF DSLR but APS-C crop cameras.
The Nikon's have 24MP APS-C sensors that are performing much better than the Canon 18MP APS-C sensors.
Now when it comes to lenses, the third party options (Tamron, Sigma) are increasingly producing optics that are very close to the that of Canon but at a huge discount. Buying Canon lenses is becoming less of a quality thing and more of a religious thing.
