The Rf24-105mm F2.8 L Is Usm Z is the world's first 24-105mm focal length lens combined with consistent f/2.8 aperture. With its constant f/2.8 max aperture, full-frame coverage, and its ability to zoom past the traditional 70mm roadblock to a true portrait-length 105mm, this lens is an incredible standard zoom solution for many different applications. An optional, dedicated Power Zoom Adapter Pz-E2 transforms the video operation possibilities with its smooth and versatile zooming. Even in low light, this lens will excel for weddings and events, photojournalism, portraiture, studio work, and video creation.Outstanding Optical Performance with Consistent f/2.8 Maximum ApertureBy taking advantage of the large diameter Rf mount and short back focus, the Rf24-105mm F2.8 L Is Usm Z is able to achieve a maximum aperture of f/2.8 throughout its entire zoom range. This enables you to continuously shoot up to the frequently used 105mm without switching lenses, opening a world of possibilities for both photo and movie shooting.Supports Optional Canon Power Zoom AdaptersThe RF24-105mm F2.8 L Is Usm Z crosses the worlds of photography and movies. The optional Power Zoom Adapters Pz-E2 and Pz-E2B enable smooth, high-precision zoom control during movie shooting. Plus, attachment and detaching can be managed without the use of a special tool. The Power Zoom Adapter Pz-E2B comes equipped with a 20-pin port for compatibility with cinema or broadcast lens accessories such as zoom servo grip or focus demand. This lens and Power Zoom Adapter combination makes unassisted single-person video shooting operation easy and within reach.Eleven Aperture Blades for Rich BokehWith eleven aperture blades and a large f/2.8 aperture, the RF24-105mm F2.8 L Is Usm Z produces a beautiful, almost circular bokeh effect - even when stopped-down. The wide aperture also allows for faster shutter speeds in low light situations and helps prevent subject blurs.Iris Ring for Precise Lens Aperture ControlThe RF24-105mm F2.8 L Is Usm Z is equipped with an iris ring (aperture control), the first among RF lenses. This allows video users to manually control exposure adjustment and the degree of background blur while shooting video, with click-less, smooth operation similar to the operability in a cinema lens.Close-focusing to Under 1.5 ft., Max. Magnification 0.29xWith a minimum focusing distance of approximately 1.5 ft./0.45m, the RF24-105mm F2.8 L Is Usm Z lens helps you get close to your subjects. The maximum magnification is 0.29x at 105mm, allowing you to capture subtle details more expansively and clearly. Focus shifts during zooming are minimal - plus, it supports focus breathing correction3, in which the camera digitally corrects for changes in angle of view caused by focus movement during video recording, especially during closeup shooting.Optical Image StabilizationFor consistently sharp results, the RF24-105mm F2.8 L Is Usm Z features built-in optical Image Stabilization, providing enhanced shake reduction for up to 5.5 stops of shake correction. When paired with an Eos R-series camera that has In Body Image Stabilization (Ibis), the Coordinated Is allows for up to 8.0 stops of correction4. This means more reliable handheld performance and clear detail in low-light situations, without having to increase the Iso or decrease the shutter speed. Additionally, an Is Mode switch is featured for the first time among Canon RF standard zoom lenses.
