Why we recommend this ▼

The 14mm f/2.8 ultra-wide prime delivers sharp astrophotography images with its fast aperture, two aspherical and two ED elements, and weather-sealed 641g body. A de-clickable aperture ring and smooth manual focus with a lock ring make it equally suited for silent video work and precise night-sky shooting.

Canon EF-S 10-22mm f/3.5-4.5 USM

54.5 Wildlife/Sports Score
10-22mm22-27Canon EF-S
Why we recommend this ▼

With an ultra-wide 10-22mm zoom (16-35mm equivalent) and a fast, quiet ring-type USM autofocus, this lens weighs just 385g, making it ideal for travel. Its 3 aspherical elements and 1 Super-UD element deliver sharp, detailed images across the frame, though the f/3.5-4.5 aperture limits low-light performance. Best for landscape and travel photographers seeking a compact, high-optics wide-angle zoom for Canon APS-C bodies.
