Some more thoughts on DX. Seeing the rumour and then soon after, news of the D7100 got me thinking, positioned as it is above the ‘mid-level’ D5200 and below true semi-pro cameras like the D800. I’m not too sure whether or not I can expect, right now at least, a D400 with such a build. The problem for Nikon would be selling it. Not only is the market for higher-end DX dwindling, it would also mean supporting such a venture, meant originally surely as a stop-gap until FX became affordable. To an extent, with the advent of the D600, this has come to pass. I say to an extent, as that is a mid-range camera with a pretty-much high-end sensor. By having a smaller sensor, you can still make all the por-level features a lot more affordable, due to cost savings. Hence all the mirrorless crop cameras, some of them quite serious machines in their own right.
In the DX world, there have been new lenses periodically released, most of them very good and here I speak of the 40mm f/2.8 macro, 35mm f/1.8 and more recent 10-24mm zoom., but no pro-level models. Even if most people are happy with DX consumer models and a potential D400 with updated sensor, AF etc would be a fantastic camera, the benefits of affordable FX are too much to ignore by enthusiasts. I’m still a DX user but can see why Nikon can only realistically offer FX pro glass right now, which of course works fine on DX despite the huge size of it. To make new pro-level DX glass would divert precious resources and they would certainly like pros to go the FX route after all.
The only problem with this line of thought is the idea that the D600 is equivalent to a D400, as in AF, build and ergonomics it is nowhere close. If I wanted to have those, I’d have to go to the D800, with its slow shooting speed, just as the D700 was the only other option earlier. I’d admit, the D800 is a much more comprehensive camera for our time, with competitive resolution and video with what Canon has been producing all these years. Still, I can’t really afford a D800 right now and I’m not taken with the build of the D600 (or either camera’s prevalent bugs!), Nikon’s taking a huge gamble in effectively raising the price of its semi-pro line to the $3000 mark, plus lenses. Alongside the D7100, with more capability than the D600, I wonder if we may still see a D400 as well. There may even be a new kit lens for it, with constant f/4 aperture. Why? Because even if DX is dying, there is still some life in it, especially for event or sports shooters who don’t need so much resolution. Enthusiast-aimed, f/4 or f/1.8 lenses are aimed at the mass market, whilst f/2.8 zooms and f/1.4 primes are targeted at uncompromising pros.
I’ve always thought the D800’s Achilles heel is its slow speed and I don’t think that would be tolerable in a leading DX camera. Whilst a lot of pros are moving to FX, many enthusiasts can’t afford to, so the gap between D7100 and D800 is massive, only partially filled by the D600, which of course has poor AF for sports or events, not even covering much of the sensor! There is lots of room for a D400, even though the distinct lack of any pro DX lenses speaks against that. People with lots of DX glass may well want a better body to use it on and from Nikon’s point of view, they may also be buyers of expensive FX gear in the future.
