Canon’s Air Sphere coating minimizes ghosting and flare to give you greater contrast and excellent color neutrality. Air Sphere gives you minimal distractions and aberrations. The 12 pin high-speed communication system processes data to your from your RF lens to your Canon EOS R camera faster than any other lens/camera combination. The RF 24-105mm f/4L lens’ large diameter rear elements capitalize on the short flange back of the RF system to contribute to the high optical performance of the image projected onto a large Full Frame sensor. The large diameter mount and the short back focus are ideal tools in maintaining higher brightness of f/4.0 maximum aperture. These two factors mean the front section of the RF lens can be physically much smaller than conventional EF lens architecture.Control RingAll RF lenses incorporate a control ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the Canon EOS R camera’s main dial and quick control dial, the ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder.DurabilityThe RF 24-105mm lens was built to handle the rigors of professional use.
