What Is Focal Length?

A lens's focal length (mm) determines how wide or narrow your frame is. Smaller numbers = wider angle, larger = more telephoto. 50mm is closest to the human eye on full-frame. APS-C sensors apply a 1.5–1.6× crop factor.

Prime vs Zoom Lenses

Prime lenses have a fixed focal length; zoom lenses let you vary it. Both have real advantages — choose based on your shooting style.

A lower f-number lets in more light and creates a blurrier background (bokeh). Use f/1.4–f/2.8 for portraits, f/8–f/11 for landscapes.
