Unless I planned on using the the lens on an old EF body I’d definitely go for the RF since it has the newer mount with faster communications capabilities. It will be interesting to see if any noticeable differences exist as people get a chance to try the RF version, especially if they already have experience with the EF.

Canon themselves have said it's the latest EF lens in RF clothing. It can't shoot more FPS or focus faster. It doesn't have the highest available stabilization stops like a true RF redesign. Just look at pictures of the RF version and you can see there's a silver adapter bolted on the end. They didn't even design new white lens body down to the mount. It's no different than if you did it yourself, except you can't remove it later.

I'd definitely get which ever was cheaper. Honestly, I'd get a used EF 400mm II. Save about half and the pictures will be the same.

Can you show me where they said it doesn’t perform AF any better? All I remember reading was that it has the same optical formula.

It's the exact same lens with the same motors, how could it perform AF better?

If it’s just the identical lens with an adapter attached, why didn’t they release it months ago????

Ask Canon.
