A wide-angle zoom lens with a constant F4 aperture that covers a wide range from the ultra-wide to standard ranges. Without having to change lenses, you can capture a wide variety of shots, such as dynamic expressions that can only be captured with an ultra-wide-angle lens at the wide-angle end of 17mm, and natural landscapes and snapshots with an angle of view close to that of the human visual system at the telephoto end of 50mm. In addition, by maintaining a maximum aperture of f/4 throughout the entire zoom range, exposure remains consistent even when changing focal lengths, making this a recommended zoom lens for both still and video photography.
High optical performance delivers detailed images throughout the entire zoom range. Effectively positioned 15 lenses in 13 groups, including three LD (Low Dispersion) lens elements, two hybrid aspherical lens elements, and one GM (Glass Molded Aspherical) lens element, efficiently suppresses chromatic aberration and other aberrations, resulting in clear, crisp images right down to the edges of the frame. Another notable feature is the rich bokeh, even at the maximum aperture of f/4, which accentuates seasonally vibrant trees, flowers, and other subjects in natural landscape photography, resulting in captivating shots.
The 17-50mm f/4 inner zoom lens is easy to handle and well-balanced, weighing just 460g and measuring 114.4mm in length, providing a well-balanced fit even when paired with a camera body. The lens also features a fixed-length inner zoom for easier framing when shooting still images and video, and for easier balancing with video equipment such as gimbals. This inner zoom mechanism ensures a tightly sealed lens barrel and excellent dust and weather resistance. Combined with its easy-to-handle size, it's ideal for active scenes like mountain climbing and outdoor activities. The AF drive of the 17-50mm F4, ideal for still and video shooting, employs a linear motor focus mechanism, VXD (Voice-coil eXtreme-torque Drive), achieving the highest level of speed and precision in its class. Its smooth focus on moving subjects, excellent tracking performance, and fast-paced shooting are a reality. The quiet AF operation makes it ideal for still and video shooting in environments where silence is essential. Incredible close-up shooting capabilities expand the scope of expression. The 17-50mm F4's minimum focusing distance is 0.19m at the wide-angle end and 0.30m at the telephoto end. The working distance at the wide-angle end of 17mm is just 5.7cm, reducing the stress of not being able to get close to the subject. By being able to get closer to the subject, you can capture a large subject and blur the background, and you can easily adjust the focus without changing your shooting position even in places where movement is limited, such as indoors.
Highly convenient and easy to use. Lens design takes convenience and operability into consideration. Equipped with a focus set button.
Simple weather-resistant construction and grease-resistant coating for comfortable shooting. [Accessories] Flower-shaped hood, lens cap. ■ Specifications ■
