The problem with the Df is not that it's an intriguing and interesting little camera. Nikon has no problem with intriguing and interesting. Like I said, 24karat Gold Plated Lizard Skin DSLR. The problem with the Df, is Nikon didn't put in the proper effort. It doesn't sell not because it's got a "retro" design. It doesn't sell because it probably has one of THE WORST control designs on the face of the planet. Stacked dials? Seriously? That's about the most useless control mechanism I can think of. Nikon rushed the Df to market. Again, probably because they felt they had to, in order to attract more interest in a niche line, because...well a) that's what they do, and b) they are having a hard time selling things like the D800 (it's total sales volume is a fraction of the 5D III.)
If Canon put their mind to releasing a retro-styled DSLR, I would bet good money that not only would they do it, they would do it right, do it on their own time table, and when it finally hit the shelves, it would sell well. Why? Because it wouldn't be impossible to control, and people would know that it had that Canon guarantee of quality behind it. It would have been thoroughly and properly tested and field vetted before it hit the streets. It would have Canon's superb and superior customer service backing it up.
Will Canon do it? Well, probably not. I'm sure some people are demanding it, but again...Canon responds to the most critical demands first and foremost, and they only have so much money to spend on R&D.
I agree about stacked knobs and what about the 1/2 stop shutter dial....hullo? The Df is a nice looking camera, but that's exactly who Nikon have gone for...looks over substance. It's an ok camera but it's UI is severaly limited. Most selections have to be made in the menu system which kind of misses the point with a retro styled camera. I suspect that a lot of buyers who are attracted to this camera want to "look" like a photographer over actually "being" a photographer. It's the strength of the images which count and not what the box looks like.
I have an old Canon A1 and AE1 program. I bought them new a long time ago...do I use these at weddings to give the impression I'm a real photographer? Certainly not! I'm hired fro my skill and reputation and not for the camera in my hands...lets fact it, anyone with deep pockets can buy a pro camera but that doesn't make them a professional.
