Good news for sports and wildlife shooters. Canon has released new firmware for five of its super telephoto lenses. These include the popular Canon RF 100-300mm f/2.8 L IS USM (buy here), along with four of the company’s big primes.
The primes are the RF mount 400mm f/2.8L IS (buy here), 600mm f/4L IS (buy here), 800mm f/5.6L IS (buy here), and 1200mm f/8L IS (buy here) lenses. All very big, all very expensive lenses.
Canon RF Telephoto Lens firmware updates
The new firmware updates are largely just to improve the panning assist mode when shooting with an electronic shutter. However, firmware updates will often include other undocumented updates and fixes, too.
So, even if you’re not facing issues with panning assist mode, it’s worth updating if you use these lenses.

This firmware incorporates the following changes.
- It is now easier to focus even during fast zoom operations.
- In electronic shutter mode, the control of panning assist after the second shot of continuous shooting has been improved.

The four prime lenses in the Canon RF super-telephoto firmware update all share the same patch notes, with just one item.
