I watched the online Nikon Z6/7 Hands-on Panel Discussion (twice) as well as watched or read user reviews on numerous web sites, but I still don’t understand why I should want or need this new mirrorless camera. I currently own a Nikon D810 and two Nikon Df’s along with a variety of AI-S, D, G and E lenses. What are the compelling reasons why I should add this camera to my current Nikon product collection or replace one of my existing cameras? And if for some reason I need a mirrorless camera, wouldn’t I be better off buying a Fujifilm XT2 with a Nikon F mount converter?

QED re Andy.

I am sorry this has become muddied up with personal things. I hope we can stay with a good discussion about perspective being changed by lenses, referring to examples. A lot purportedly showing that lenses do not affect perspective were shown in the other thread, "Does perspective change when you change the focal length?" Those examples were dealt with, primarily showing that their claims were false (with real pix and noting overly controlled situations), and the explanations were very poor, lacking in required knowledge of linear perspective. So, you might want to go there first. Certainly not required.

I suggest we stay with the examples, and show why and how they are wrong if that is your decision.
