Thanks for all the replies.
I'd explore Zeiss options but AF is a must for me. Children and weddings don't always wait for MF.
I expect people were seeing you were a portrait photographer, and thinking either you were mostly working with posed subjects where you could much more easily use a MF lens. Children (especially running around) and weddings definitely need to have a good AF lens. From what I've heard, the Canon 85L tends to focus slower than many other lenses, although on a 1D body it AF a bit faster.
Really, pros these days will choose L for the build quality, weather sealing and reassurance that they will work and get the job done. Sharp all around and will last a good while
This is my impression as well, and while I'm not a working professional, the weather sealing and build quality are a big factor for me. That said, there are some 3rd party lenses that are seriously challenging Canon's L lenses, such as the Tamron 24-70 I'm considering. Not sure how weather sealed it is, but the build quality certainly seems pretty good, and IQ seems to be better than the Canon 24-70 v1. Sigma, as you've noticed, certainly has a few new lenses which seem to be doing quite well, and something I may consider when I need those focal lengths.
