Canon EF 17-40mm f/4L USM 17-40mm
The constant f/4 aperture and L-series optical design with one Super UD and three aspherical elements deliver consistent sharpness across the full-frame zoom range. Its weather-sealed, durable construction is paired with a remarkably light 57g weight, making it a highly portable ultra-wide option. This lens is best for travel and landscape photographers who need a rugged, lightweight zoom and can work without image stabilization.
