Something is turning on the 1 ev bracketing steps, normally it is 0 ev indicated if bracketing is off.
Be sure to shoot at the lowest ISO and use spot or center only if you want the high tones of the sky to blow out. Matrix, ADL on Auto and RAW will pretty much take care of any high tone clipping if shooting into hazy bright scenes like your.
The DR of the D7000 is actually very good and has over 11 stops. Film is non-linear in response so it might appear to have more DR but it does not since it compresses high tones before total saturation onsets, leaving little recoverable tone gradient.
Shooting RAW format and processing the files on your computer will reveal that there is a lot more data recorded and tone range captured than can be seen on your monitor. Boosting the contrast a little in post processing, not in-camera, (unless you are shooting JPG) will reduce highlight clipping as will ADL being turned on.
Default settings come from the factory with lower contrast and sharpening than you would probably want. If shooting JPG, create a Picture Control with sharpening and contrast boosted a little and you will see a big difference seen on a monitor. If shooting in RAW, those controls do not impact the image file and sharpening is done in your computer. Stan St Petersburg Russia
