This is a professional telephoto zoom for Canon's EOS-R mirrorless system.
Fulfilling the dream of mirrorless and quite different from Sony's bloated 70-200/2.8 GM, this Canon RF 70-200/2.8 is much smaller and lighter than any similar mirrorless or DSLR lens. It's about half the length of other 70-200/2.8s
Canon expects the lens — and full specifications — to be available towards the end of 2019.
The RF 70-200mm F2.8 L IS USM is a must-have for any professional photographer, especially for those shooting weddings, sports or wildlife. This lens is a great all-around, high-speed, medium telephoto zoom lens and does well to round out any camera bag
