I've not used a Nikon APS-C camera in awhile. My last one was the Nikon D90.. quite a bit has changed. Note that I have not owned and rarely used the D7000/D7100, so for upgraders this might not be a good mini review. I've been using the Nikon full frames for awhile (D600, D810, Df) and been wanting to get a crop factor camera for birding/macro purposes.
Few observation/gripes
1. I can't find the 'ISO display and adjustment' option. My d90/d810/df has it. The only way i can get ISO to show on my OVF now is by enabling EasyISO.
2. The top LCD is now very simplified. (Numbers are larger too) I cant see the AF selected points on the top panel now. (Since there's no tilt, i tend to use that to see the AF point and angle the camera from waist height
3. The shutter is signifcantly quieter then my D90 in my opinion. On a noisy street, its quite discreet.
4. Wifi works well with my iphone. No password when u first enable, but its easy to configure it via the phone. (Wonder why nikon dun let u configure via the camera) You can select images to be send to smartphone/wifi on next connect. (Something that seems to only exist on builtin-wifi cameras.. I don't get that on my df+wifi adapter.. I wished i could just use a dedicated button in play screen to instantly mark my photos. (On my D810 + eye-fi i can use lock to mark photos)
5. I didn't get to test NFC (iphone user.. haha) and its enabled by default on the camera. I switched it off.
6. Liveview autofocus is decent. I don't plan to use it but its good to have. The AF points in OVF mode is very well spread out and I doubt I need to use liveview to autofocus on the edge. (Note that the aperture behaviour is like the D600, you need to take a shot to change the aperture)
As mentioned, I'm new to APS-C nikons, and if any of the above is obvious to you, I apologize.
