Combining a constant f/4 aperture with 5-stop optical stabilization, this 45-100mm zoom delivers sharp results across medium-format sensors using 3 aspherical and 2 ED elements. Its dust- and weather-resistant build operates down to 14°F, backed by a near-silent linear motor for discreet autofocus. This lens is best for landscape photographers who need a rugged, stabilized telephoto zoom for unpredictable outdoor conditions.
