What is a excellent Nikon lens for portrait and landscape? I still want to be able to have the bokah in the background

Guys what is a excellent Nikon lens for portrait and landscape? I still want to be able to have the bokah in the background - 1

A medium telephoto lens will probably produce pleasing out of focus backgrounds when shooting portraits, IF

* you place the subject at least 30 feet ahead of any background
* if you make sure that the background is neutral, not full of busy shapes
* use the largest lens aperture to produce shallow depth of field
* place the subject close to the lens

Wide angle lenses are 1) used for shooting landscapes and 2) have too much depth of field to produce pleasing out of focus backgrounds.

That's what the 18-55mm is for.

Learn to get the best out of it, and you'll be able to answer this question for yourself.

I'm guessing that you're shooting a DX body. Like Andrew pointed out, the 18-55mm kit lens is very versatile. However, if you want to "kick it up a notch," then the Nikon 17-55mm f2.8 would be an "excellent," albeit expensive, choice. See link.

You asked for one lens for doing portraits (short tele) and landscape (wide angle) with bokeh. The answer is the kit lens. Yes, that 18-55mm you already have. It has short tele at 50mm up and wide angle at 24mm down. For bokeh, if you set the subject far away enough from a glittery background and put the camera as close as possible to the subject using f/5.6 at 55mm then you'll get bokeh, all right.

In a perfect world, you'd have two lenses for this: an ultra-wide like the 14-24 f/2.8 for your landscapes, and a 24-70 f/2.8 for your portraits. As a one-lens option, the 24-70 f/2.8 would be the lens to get. Go to photozone.de to see how sharp the various lenses compare from Nikon, Tamron, Sigma and Tokina. You just may be surprised.

Thank you for teaching me a new word - BOKEH!

I just realized that I'm getting old when "depth of field" becomes a one-word art style!

You need lenses which open up to a wide aperture - as wide as possible. With film, this used to be f1.2, f1.4, f1.8. I'm not sure what digital can do nowadays.
