|Nikon D750 with AF-S 24-120 f/4 VR|
- The D750 is not an outright action camera.
- It is also far better than an entry-level FX camer.
- It doesn't solve DX users needs
... With those points out of the way, it's fair to say that the D750 is an extremely capable camera in its own right. Nikon threw the proverbial kitchen sink into the D710. Except for the full metal body and "pro-level" control layout of the D810, the list of features not on this camera is fairly short. Though it's "another 24mp camera" the D750 has broader market appeal than the D810 and ticks off more of the check boxes that enthusiasts watch for than the D610. In other words, it's not as much of an "action camera" as people had hoped for, but it is ostensibly being set up to be a big part of Nikon's FX lineup. In that sense, the D750 is like the middle part of a restaurant menu; it's the option that they think most people will pick. It looks affordable next to the premium option, but it brings in more money that the value option that they hope you will steer away from.
