Canon L EF 17-40mm USM 40mm
Combining L-series build quality with a constant f/4 aperture, this 17-40mm zoom delivers consistent exposure across its range and features a Super UD element with three aspherical elements to curb aberrations. Its weather-sealed, 499g body and ring-type USM motor provide silent, fast autofocus with full-time manual override, making it a durable and portable wide-angle option. This lens is best for full-frame landscape and architecture shooters who need a rugged, affordable ultra-wide zoom with a constant aperture.
