I vividly remember my experience with AFD lenses. 24/2.8 and 135/2.8 (IF design) were faster, sometimes noticeably so, than 35/2, 50/1.8 and 50/1.4 which extend during focusing. So I guess we'll have to agree that we disagree on that.

IF/RF designs are faster than extension systems unless somebody messed up the mechanism. I would agree here.
