When you're ready to shoot, just unlock to extend the lens barrel, lock it in place for stability and capture your shots, then unlock, retract, and store again to easily move to your next destination. Gapless Double-Layer Diffractive Optics (DO).
The use of gapless dual-layered diffractive optical elements helps reduce chromatic aberrations so your images are clear and detailed for high-quality results all around. And because one DO lens has the optical characteristics of multiple lenses, this contributes to the lightweight of the lens itself, as well. High Image Quality at a Fixed f/11 Aperture. Impressive results are always the goal and with the RF 800mm lens and its use of diffractive optic elements, chromatic aberration can be virtually cancelled out to achieve clear images with minimal to no color fringing, even at a fixed aperture of f/11. This means detailed results of landscapes and more, even from a distance.
Steady and clear images aren't always the easiest to come by, especially when shooting with a super-telephoto lens, but with the powerful image stabilization function in the RF800mm, you can feel far more confident it won't be an issue. Whether shooting handheld or with a monopod, the built-in IS with up to 4 stops of shake correction helps to significantly reduce camera shake to stabilize the image and get you the results you want and need.
Lead Screw-Type STM Enables Smooth Autofocusing. The use of a lead screw-type STM focus motor means smooth and quiet autofocus can be achieved whether you're shooting stills or tracking a subject while shooting video.
While it's nice to be near-silent anyway, it's especially important in instances where you're trying to capture the flight of a wild bird or the relaxation of a wild animal. With the STM feature of the RF 800mm, you can capture the scene while significantly reducing the chance of the subject being disturbed. Control Ring for Direct Setting Changes. Like all RF lenses before it, the RF 800mm lens comes with a customizable and easily accessible control ring so you can change settings like shutter speed, aperture and ISO while still looking through the viewfinder.What's in the Box.
