On the 2nd and 3rd paragraphs of this the writer explains that he is in 2017. The article is obviously a bit old but seems to have some useful information in it.

I read the article, I think he needs to update some of his information. The author brings up the Nikon D800 and compares it to the other cameras he likes. He should have used the D850 which is a more current model. Also when he talks about Canon Professional Service he didn't mention there are different levels and depending on the level, you have to pay for your membership. Nikon Professional Service is free.
