Kinds of Nikon Camera Lenses?

I want some Nikon DSLR camera lenses. I'm mostly interested in shooting everything, I like bokeh photography a lot, also I like to shoot slow motion (water drops etc.)

Another teenager who likes bokeh… Yay… Check out Nikon's website. Http://shop.nikonusa.com/store/nikonusa/en_US/list/Camera_Lenses/categoryID.43887400

Nikon's lenses could be classified into 3 types.

Consumer-grade AF-S. Cost is $
Pro-grade AF. Cost is $ to $$
Pro-grade AF-S. Cost is $$ to $$$

More or less.

If you have an entry level Nikon (D3000 and D5000 series) then you can't autofocus with the Pro-Grade AF. So your only options are the Consumer-Grade or Pro-Grade AF-S lenses.

If you have an advanced camera (D90, D7000, D300, D700, D3s, etc), then you can autofocus on all three lens types.

But the lens has nothing to do with shooting water drops, or what you call bokeh. Those effects are done with using the proper exposure and composition techniques, and can be done with just about any Nikon lens.

There's a misconception that bokeh = blur.

This is incorrect.

Blur, or a blurry background, is the result of a shallow depth-of-field.

Bokeh is the quality of the blurry background, not that the background is blurry.

So you could have a background that is blurry and that has good bokeh or bad bokeh. Good bokeh means the background is pleasing; and terms such as milky smooth, cream cheese, and buttery are sometimes used to describe this. Bad bokeh is usually a harsh looking background, and even though it is out of focus, it's harshness detracts from the main subject.

Bokeh itself is dependent on things such as the lens design, number of diaphragm blades in the aperture, and so on.

To get a blurry background, which is needed for good or bad bokeh, you have to have a shallow depth-of-field, which is comprised of three things:

1. The closer the subject, the shallower the DoF
2. The longer the focal length, the shallower the DoF.
3. The wider the aperture of the lens, the shallower the DoF.

All three things work in conjunction with each other. So to get the most shallow depth of field, open your lens wide open, adjust for the longest focal length, and get your subject as close to you as you can.

Any DSLR and lens combination can do that to some extent. If your combination is not as good as you would like, get a faster lens (wider aperture) or a longer focal length lens.

And which DSLR do you have? There's no bokeh photography, bokeh is an "effect" that depends on the lens and its aperture. Slow motion water drops also have nothing to do with lenses.
