The RF600mm f/11 IS STM and RF800mm f/11 IS STM incorporate a gapless dual-layered DO lens element made from new materials. Streamlining optics with one lens element that can do the work of at least three Key #3: The capable, multi-tasking DO lens element The lens’ AF mechanism is driven by lead-screw type STM, which realises fast, accurate focusing during still image shooting as well as smooth, seamless focus tracking during video shooting. It is no exaggeration to say that Canon has achieved an f/11 lens design that is truly viable. This is also thanks to the Dual Pixel CMOS AF system on the EOS R system cameras, which can acquire focus even at f/11. When using the RF600mm f/11 IS STM and RF800mm f/11 IS STM, phase detection AF is possible over 40% × 60% (horizontal × vertical) of the image area. It gives you beautiful bokeh even at f/11, but also means that you will be grateful for any autofocus (AF) help that you can get! Super telephoto lenses, by nature, have a shallower depth of field. Yes, you still can enjoy fast, accurate autofocusing Key #2: Autofocus is (still) possible at f/11 Use ISO AUTO mode to achieve the correct exposure via ISO speed adjustment. * As the aperture is fixed at f/11, when shooting in Av, Tv, P and Fv modes, the camera will not be able to adjust the f-number to compensate for other exposure settings. In fact, the benefits of a fixed f/11 aperture outweigh the cons: no aperture adjustment mechanism means you get a lighter, smaller lens that is much easier to carry around.ĮOS R/ RF800mm f/11 IS STM/ FL: 800mm/ Aperture-priority AE (f/11, 1/125 sec)/ ISO 1600/ WB: DaylightĪt f/11, not only you can capture your subject in sharp detail, it is also perfectly possible to achieve a beautiful, creamy background blur. While you wouldn’t be able to adjust the aperture setting to change the depth of field, in actual use, f/11 is sufficient for many scenes, especially when paired with the excellent low light capabilities of the EOS R cameras. But the excellent noise reduction capabilities of the EOS R system ensure that high ISO speed image noise is nearly non-existent. With a narrower maximum aperture, you will find yourself shooting with a higher ISO speed more frequently. It makes the lens so much more portable, you’d use it more than you think! As a result of their efforts, both the RF600mm f/11 IS STM and the RF800mm f/11 IS STM are around 70% lighter than the existing EF counterparts, and are substantially shorter and smaller even when fully extended.į/11 is capable of excellent photos in many scenes The retractable lens barrel design (which includes a locking mechanism): Users extend the lens barrel to shoot, and retract it for storage.īuilding on these fundamentals, the Canon lens developers took advantage of three different features to make a smaller, lighter lens design possible. The characteristics of the RF mount: The large mount diameter and short flange focal distance maintain image quality at a high level. There are two important base features that laid the groundwork for these radical new lenses: How did Canon manage to achieve them not one, but two lenses? “Affordable”, “lightweight”, and “compact” are usually the last words anyone would use to describe a super telephoto lens. Designed to make the joy of super telephoto photography more accessible to enthusiast photographers, these lenses are set to be the new must-haves especially for those who love photographing wild birds, wildlife, airplanes and sports!Īt 600mm or 800mm, you will be able to capture close-ups of candid facial expressions on cautious wild animals, raw emotions on the faces of athletes at the peak of sporting action, or even airplanes flying high in the sky.ģ keys to an affordable, compact, lightweight design Up to now, super telephoto lenses have hardly been associated with the words “compact”, “lightweight”, and “affordable”, but this is set to change with the RF600mm f/11 IS STM and RF800mm f/11 IS STM. Impressive close-up shots, made more accessible than ever Unbelievably compact, lightweight, and wallet-friendly, the RF600mm f/11 IS STM and RF800mm f/11 IS STM are set to bring the joys of super telephoto photography to more people than ever. On 9 July 2020, Canon announced two new super telephoto prime lenses for the RF mount.
