Quiet, light, and wide lenses for A99 video?

Brand new A99 user here, looking for some recommendations for lenses to use for video with AF on.

My criteria:

Quiet.  Silent focus in AF mode with the onboard mics.

Light, so i can hand hold with one hand easily.

Wider than 50mm.   I have the DT 35mm, which is both quiet and light, but I'm looking for wider than the APS-C mode ~55mm equivalent.  Something in an effective 24 - 30mm range.

From this forum, I've gathered that the Sony 16-50MM is quiet bc of the SSM and good for video.   The range would be fine for indoor video in APS-C mode on the A99...  A bit heavier than I want.

Anything lighter?  Totally okay with 3rd party or Ebay Minolta lenses.

(If Sony would copy Canon's ultra slient, flyweight 40mm pancake, I'd be all over it.)

thanks.
