Canon has released new firmware updates for the Canon EOS R5 and EOS R6 mirrorless cameras. The EOS R5 specifically sees some AF accuracy optimisation when using the recently announced Canon RF 800mm f/5.6L IS USM and RF 1200mm f/8L IS USM lenses with the RF1.4x and RF2x teleconverters. Both cameras, however, see improvements to the stability and reliability of Eye Detection autofocus as well as AF tracking for moving subjects.

Both firmware updates are available to download now from the Canon website.

Canon EOS R6Firmware Version 1.5.2 incorporates the following enhancement:

I haven’t seen any videos yet showing off how well the improvements work in the new update yet, but I’m sure we’ll start seeing some pop up soon. But, if you’ve got one of these cameras, you might as well just go ahead and do it. Somebody has to. What’s the worst that can happen?
