Is the Nikkor 10mm f/2.8 good for landscapes?

It's good for wide angle dramatic landscapes, yes. But you can use any lens to shoot a landscape - even a telephoto can be used to isolate a particular element in a landscape.

This particular lens is for the Nikon 1 system - are you aware? The crop factor would give it an equivalent field of view to a 27mm lens on a 35mm camera system.

Yeah

If that is the focal length you need for the style of photos you want to take, then yes. I personally use a 50mm or 100mm lens for landscapes.

It'll be fine… Reasonable IQ and large max.aperture - Good features to have.

The widest I use for landscapes is a 14mm f/2.8 on a full frame camera.
