How to choose a camera lens
Understand compatibility, focal length and aperture, then choose a lens that solves a real photographic need.
Find your focus
Understand focal length, aperture and compatibility before choosing your next lens.

Know what matters
The right lens solves a photographic problem: fitting more of a room into the frame, working with available light, photographing a distant subject or getting close to a small detail. Begin with that purpose, then check whether the lens works fully with your camera.
Our lens buying guide explains focal length, prime and zoom lenses, maximum aperture, stabilisation and the difference between mount fit and full compatibility. It also covers what to check when considering a used lens or a camera-and-lens bundle.
Write down your camera’s exact model and sensor format before shopping. A familiar brand name, or a similar-looking mount, is not enough to establish that every feature will work.
Our guides help you prepare a shortlist; live retailer comparisons are planned. When comparing offers yourself, include delivery, required adapters and the warranty terms in your decision.
