...For example, I’ve shot with the EF 16–35L, 35L, 40/2.8, 50/1.8, 135L, and 70–200L, and it was quite clear that the autofocus performance of the 40/2.8 and 50/1.8 was not on the same level as the 70-200L.
On higher-end lenses such as the RF 28–70mm f/2L and the RF 50mm f/1.2L, the Canon versions still don’t match the autofocus performance of their Sony counterparts, possibly because Sony uses more motors (four) to drive the heavy glass elements.
Comparing 7x more expensive lenses with the cheapest there is and finding differences. No, not much wow-factor there. But you may still have a point in that AF may be slower than necessary from the economic angle of view. Could Canon be the only one to do this? Any bets for?
As for the heavy hitters, both Canons are from 2018, the Sony 50 is 2021 and the 28-70 is from 2024. The conspiracy inclined do, of course, find the obvious pattern that Canon has made the Version 1 slow, so they can milk the market by getting a faster v.2 out far sooner than Sony has to. Who can say? Could be! Or not!
Yes, I do hope Canon improves all the slow focusing L glass, including the RF 85/1.2… the RF variant is somehow as slow as the EF variant.
