He might have some legit points. But I object to the snarky sarcastic tone. If someone wants to buy a Nikon Df to take pictures at $3000 rather than spend the money on a new car or the like, that’s none of his business. The D600 is essentially the same sort of camera for $2000 so you are spending the extra $1000 for the retro styling.
On this blog we have countless art sculptures that have no functionality and cost lots more than $1000 to build. Until Datamancer passed away, many of us queued up to spend $1000+ on what was essentially a $40 keyboard in drag.
The Df does not pretend to be anything it isn’t. It is simply a lighter weight, cheaper version of the D4 with one major feature taken out for people who want to be seen with a stylish camera but don’t want to lug a D4 about. It is certainly not for everyone. In fact I would suggest it is for the sort of person who goes round with a PA to look after them.
Nikon only needs to make 10,000 or so a year to mop up the lower spec D4 sensors and they will have no shortage of buyers. They come out with bling editions every couple of years, the last one was a gold plated D5200. They sell out without any difficulty at very high prices.
