What Is a Prime Lens?

A prime lens is a lens with a fixed focal length. That means it does not zoom in or out.

For example:

35mm
50mm
85mm

Unlike zoom lenses, you move your feet instead of rotating a zoom ring.

Why Should I Buy a Prime Lens?

When I switched from a kit zoom lens to a prime lens, I noticed three big improvements:

1. Sharper Images

Prime lenses are usually sharper because they are optically simpler.

2. Better Low-Light Performance

Most prime lenses have wide apertures like:

f/1.8
f/1.4

This allows more light in.

3. Beautiful Background Blur (Bokeh)

If you love portrait photography, prime lenses create that soft blurred background look.
