1) Nikon has not been sitting on its hands. The D500 did not suck, and a 200-500 f/5.6 IS lens for $1,400 is something a lot of Canonites would give their left nut for.
If you are after reach on a limited budget, the D500 and the 200-500 F5.6 combo blows any Canon combo in the same price range out of the water. The 7D2 and the D500 are a fairly even match (I would put the D500 ahead) as some features are better on one, and some are better on the other.... but for reach with a Canon lens at that price?
Yes, I am a Canon shooter, but I am neither blind or delusional. Nobody is ahead on everything and people need to evaluate based on their needs, not some opinion on the internet or a review site.... and when you evaluate, look at body, YOUR ergonomics, lenses, flashes, accessories, batteries, software, service, support, sealing..... everything!
