Canon L 2526A004 400mm
Combining a constant f/5.6 aperture with Super UD glass and a 1270g build, this 400mm prime delivers sharp handheld telephoto reach. USM autofocus provides fast, quiet operation, and full-time manual focus plus internal focusing enhance precision, while the built-in hood and detachable tripod mount simplify field use. It’s best for wildlife photographers who need a lightweight super-telephoto without stabilization, though the f/5.6 aperture and lack of weather sealing limit low-light and harsh-environment shooting.
