Nikon D7000 fast 50mm lens, bokeh?

What's a good and fast 50mm DX lens for photo and hd video for my Nikon D7000? And why? Preferably, a lens that results and cream like bokeh.
If you can post a link that would be great.

Nikon Nikkor AF-S 50mm f/1.4G

Love this lens for those closeup shots. I needed a lens with a high F stop and I love to take portrait shots and it works great for them. The background blurs just like I needed it to!"

The Nikon AF-S 50mm f1.4 should give you the results you want. On your D7000 it will have the equivalent angle of view of a 75mm lens on a full-frame DSLR (D700, D800, D3, D4) which makes it a good portrait lens on your camera.

You are not going to get the best cream cheese type bokeh with a 50mm lens.

You will get limited depth of field, but only average bokeh.

To get great bokeh, look for a lens such as the Nikon AF 80-200mm set at 200mm and f/2.8.

The reason the 200mm lens is so good is thatt he DoF is very narrow, and when you add to that the 9 blade aperture diaphragm, it makes great cream cheese bokeh.

Here is an example of the creme cheese bokeh with that lens. The green background is just grass on the ground about 4ft behind the bird.

And if you want good Hollywood bokeh, this lens does that too:

By the way, cream cheese bokeh describes a smooth milky-like background. Hollywood bokeh is how points of light act, and if they are not sharp or have donut shape, that is usually considered the best.

Here are a couple examples of bad bokeh:

This bokeh is harsh, and the result of a cheap lens:

This bokeh has donut holes in it - very bad looking, and comes from a mirror lens.
