I noticed that Rudy Winston made a point of saying that the new f/11 lenses will autofocus on the R5 and R6. That immediately suggested to me that they may not autofocus with, say, the R. This could have something to do with the new Digic processor. If so, kind of a drag.

I was more interested in the new lenses than either new camera. If I decide to splurge it will probably be more in the direction of the 100-500L than the R5, at least this year.

At f/11, they will

Now, the R/RP unlike the R5/R6, are not rated to f/22, so you're ability to use AF with those new DO lenses on the R/RP, is probably limited to f/11.

I suspect though most people don't want to stop down.

Likewise though, using the extenders on the R/RP means you likely would have to use manual focus.

Just to mention (apologies if you already know) that the 600mm and 800mm f11 lenses cannot stop down - rather unusually, they are fixed at f11.
