Hard disagree. The RF 35mm is both very good optically and exceptionally versatile due to its close focus capabilities. While the AF speed is not laser fast, unless you are going from macro range to long distance, AF is actually very quick. So if you're shooting candid portraits or street shooting, the AF is plenty fast enough.
Was going to say, I certainly havent noticed it being "slow" when using it, Ive had plenty of L lenses in the past too. The old 85mm 1.8f EF, now that was slow, lots of AF hunting if I recall! Love the 85mm focal length though, really sits in a happy place for me. This RF is very tempting.
