Next month, Canon will release a firmware update that fixes an autofocus problem reported by RF 70-200mm F2.8 L IS USM telephoto lens owners. The company says it's confirmed this lens may produce a 'slightly front-focused' image when the photo is captured at close range with the focus distance set to around the 200mm end of the scale.
Canon will release the firmware with a bug fix for this problem in January 2020, the company revealed on its US website. The new firmware will be intended for RF 70-200mm F2.8 L IS USM lenses running firmware version 1.0.5 or earlier, something that can be checked within the camera's menu.
The Canon RF 70-200mm F2.8L IS USM telephoto lens is available from B&H Photo and other retailers for $2,699.
