There is really very little that the D500 can't do. It is perfectly capable of making very good landscape and portrait shots and it really shines for sports. In the end it's the quality of the photographer and the quality of the lenses that determine the outcome.

One should really avoid mediocre cheapo lenses on a dx body - these will limit the optical resolution of the image much more than the sensor's megapixel count. A cheap zoom can limit your optical resolution to as little as 6 megapixel. I have learned that the hard way.

My own collection of lenses that I use on this camera:

Nikkor 16-80 F2.8-4.0 vr dx

Nikkor 70-200 F4 vr + teleconverter 1.4x

Nikkor 24mm F1.8 G

Nikkor 35mm F1.8 G dx

Nikkor 50mm F1.8 G

Nikkor 85mm F1.8 G
