Canon RF 100-400mm f/5.6-8 IS USM
The constant f/5.6 aperture across a 100-400mm zoom range provides consistent exposure control for wildlife and sports, though the 2268g weight demands solid support. The bundled IP67 weatherproof hard case adds practical, dust- and water-resistant protection for transport and storage. This lens is best for outdoor photographers needing a versatile telephoto reach for distant subjects without a premium price tag.
