Remember there’s a 1.0.5 lens firmware to install first.
Sorry, but I've read and reread instructions, I don't see that is a requirement. Here's from Canon Europe:


Quote from link: "This firmware update is for lenses equipped with firmware versions 1.0.5 or earlier. If the lens's firmware is already version 1.0.6, it is not necessary to update the firmware." (Emphasis added.)

Seems like great news. Now all I need is some Black Friday discounts in 2021, which might give me enough time to save up after 2019's expenditures...

See Canon, this is how you should’ve handled my dreaded 1d3 when the first reports were in :ROFLMAO: :p

I commend Canon for this fix, it was acknowledged very fast, so they pay attention to forums, ha! To punch out the firmware this fast is excellent service. Bravo!

How great it would be to see some before and after shots, or see lensrentals.com assess the fix!

And I suppose the world will never know if anything has been tweaked physically for the next production run...???

With how much software is already working in the RF lenses (Focus by wire, control ring, cropping the sensor to match the image circle, and so on) I believe they would prefer to solve it on that layer rather than touch the production process.

Does the 70-200 really have 2,6 stops of vignetting at 200mm.? I’m baffled...

I still believe Canon was a little aggressive with the MFD claim. Really pushed it to show it is different from the EF version. For marketing. But apparently they are making it work as claimed.
