Large APS-C (23.6 x 15.8 mm) sensor
Large sensor in Nikon D80 ensures a good low light image quality compared to smaller sensors, and it also provides higher pixel quality compared to smaller sensors.
Making fine focus adjustments using live view is more precise than using a viewfinder. Very Low Resolution Sensor: 10.0MP
Landscapes photography is where you need the maximum resolution. Unfortunately Nikon D80's 10.0MP sensor doesn't deliver much and limit you with smaller prints and less fine details. No Environmental Sealings
Landscape photographs are taken outdoors and you should be prepared for all kind of weather conditions.
