Df is a great camera, it's a D4 with a much lighter body, it has legendary low light performance and is the Holy Grail of adapting manual focus Nikon glass to a digital FF body, it will natively mount pre-AI lenses back to 1959. It has the AF from a D610 so don't plan on shooting sports with it.
I don't regret my purchase, you can get them cheap. Baker Photo in Oklahoma has a black one for 1700 in EX condition. Check UsedPhotoPro too that's where I found mine and I paid 1430 for it.
