No matter how obtuse or exagerated or irrational this person's beef is. . . . it does make you remember that it was NIkon that had better AF and better ISO and DR . . . . . dare I say "ETC, etc etc."
Like most companies, sometimes I get the odd feeling that Canon buys the cheapest rods and the best hooks to get most of the fish in the sea.
It does make you wonder why a company that creates these 150MP sensors, and manufactures all these medical systems, etc etc etc, that they can't be at least on par with ISO and AF with Nikon . . . until NOW, anyway. Even the better mnenue system on the Nikon and ergonomics . .. until NOW.
I love Canon, and I appreciate Nikon.
It's just a bunch of random hate. I skim read it.
The odd thing for me is that people think the grass is greener on the other side.
I know Nikon shooters. My friend bought a d4. He's found his viewfinder has a section which is out of focus. I held his d4 in my hands and it was really quite uncomfortable in my hands. There's loads and loads of problems with the d800 - some pretty significant ones it seems - and a retailer recently said that Nikon is lying to them about when their cameras are arriving.
Things are not perfect on either side and the sooner people realise that, the better
