The Nikon D-500 is in a different world than the Canon camera's being spoken of. Do your research! Also, Ken Rockwell is NOT, an unbiased author, regarding Nikon vs. Canon equipment! He totally, favors Canon, at Nikon's expense, for his own, personal reasons! (Just read, very carefully, all that he says, about Nikon, in his "new" Nikon Information, and then, go back, and read EVERY WORD, that he had previously written, about Nikon! (Back when he was hoping, that they would be sending him, samples to test.) You will find, TWO COMPLETELY DIFFERENT and CONFLICTING OPINIONS of Nikon Cameras! It is very extreme, obvious, and blatant! He now, pushes Canon, as very hard, as he possibly can!
While the Canon 7D Mark II is a fine camera, it isn't in the same league as the Nikon D-500, but rather akin to the Nikon D-7200, which I personally, chose over it, having the ability, to purchase, either one, and seeing the D-7200, to be a better camera, for my general use.
The Canon 7D Mark II shines as a camera for sports/action/and BIF. It is not great, for general usage as the D-7200 is. Actually, the D-500 suits itself, to those same purposes as the Canon 7D Mark II, but it, will do a better job with them; as it's a superior camera.
The Canon 80D, is on the level of the Nikon D-7200, except it's image sensor, isn't as good, (yet, the 7D Mark II's sensor, is downright pathetic!)
Comparing the image sensors that are in the Canon 7D Mark II, and the sensor that's in the Nikon D-7200, this, is the actual scientific, measured data, that DXO LABS, have measured and documented, and is available for all to see on their website, at:
www.dxomark.com.
The overall sensor rating, of the Canon 7D Mark II, is 70, that of the Nikon D-7200, is 87.
70, is very low and poor, 87 is up with the full frame (Nikon) camera's. The measured, maximum dynamic range of these two image sensors, is: 7D Mark II= 11.8 D-7200= 14.6 This is a horrendous difference! The highest ISO that each camera, can take an image, while keeping noise below the prescribed level: 7D Mark II= 1082. D-7200= 1333.
The D-500 hasn't been tested yet, but it will be. considerably better. than the D-7200!
The Canon 7D MK II's strength is it's FPS speed, and that it's auto-focusing system is well suited for sports/action/BIF; the Nikon D-500 even much more so. The D-7200, much better, as a general purpose camera.
The Canon 80D, a good general purpose camera, it's sensor is rated at 79 overall, 13.2 dynamic range, and 1135 low light ISO.
The D-7200 has a better image sensor. You would need to carefully compare these cameras to select one that you prefered. Yet, still, the D-500, is, in a class of it's own!
These are facts and my opinions.
