Important note: 43mm lens cap is what the EF-M 22mm F/2 uses.
I’m pretty certain this means the RF 16mm f/2.8 is going to be *absolutely* tiny.
The EF 40mm f/2.8 even used a 52mm filter thread, which is 9mm bigger!
In fairness, by the time the R3 ships the RF 400mm f/2.8 and 600mm F/4 should hopefully actually be available, which covers most of what the high end sports photogs use. I would say a 100-300mm f/2.8 would be the perfect lens for the R3, but Canon will definitely keep us waiting on that.
