Ooops, yes I meant the 17mm TS-E.I presume you meant the TS-E17. The advantage of AF with tilt lenses is in dynamic situations, I’d love my TS-E50 to have AF for portraits, set the tilt first, then select an AF point then get that point on the eye you want and boom.
For what I use my TS-E’s for 90% of the time AF would offer no additional value, but that is a function of the fact that they didn’t have AF, once they do that will change.
I agree the AF function could be of some help but for the few times of use it would mean giving up the silky smooth MF feel of the current lenses for terrible focus by wire.
Additionally we are talking about a 14mm and a 24mm lens here, both of which don't generally get used for portraits, close up or still life photography. Can't say I've ever wished for AF on the current 17mm or 24mm TS-E's.
