A trend currently underway in the world of optics is to reduce size and weight with the same focal length and aperture compared to old optics, especially reflex ones. At home Canon those who have started shooting with the pentaprism have always found themselves at a crossroads when choosing from the 70-200mm catalogue: opt for the bright F2.8 and stabilized version, with relative weights and dimensions, or choose (also for economic reasons often ) the small, light (and very functional) 70-200mm F4 zoom.

Now (price aside) the choice is much more simplified, as the new Canon RF 70-200mm F2.8 L IS USM It comes with a weight of 1.115 gramsi.e. 25% lighter than the EF version. The lens is 199 mm long and has a diameter of 89 mm (82 mm filter holder). offering internal zoom mechanism. To better match the kit of photographers and videomakers, the new zoom will be available both in the black version, both in the ‘historic’ one of the white L sports lenses.
Canon RF 70-200mm F2.8 L IS USM adotta un design da 18 elements in 15 groups3 aspherical, 2 Super UD, 1 UD. The aperture has 11 blades and the lens has a physical aperture ring, as well as customizable buttons. The minimum focusing distance is 49 centimeters at the minimum focal length and 68 centimeters at the maximum focal length.
The optics are stabilized with OIS systemcapable of working in collaboration with the camera bodies’ IBIS stabilizer to achieve up to 7.5 stops of stabilization on a camera like the Canon EOS R1.
The optics allow you to take advantage of the RF 1.4x and RF 2x teleconverters to further extend the focal lengths in the telephoto direction up to 400mm.
As seen for the new pair of Canon RF 24mm F1.4 L VCM and RF 50mm F1.4 L VCM fixed lenses, great attention has also been paid to the video world in this case, adopting the same structure as the RF 24-105mm zoom F2.8 L IS USM Z: in this way the two lenses are perfectly interchangeable when mounted on gimbals and follow focus systems.
