Manual focus is really a non issue on a lens this wide, using the simple hyperfocal settings.

For me, infinity was easy to find, and lack of auto-focus was a non-issue

And the only complaint is about pillow shaped distortion, that for some people is annoying and others a non issue.)I suppose for someone shooting an APS-C camera, like many Sony NEX, the lens hood thing might now be a big issue (at least not as obviously visible, thought still not in the right place or doing the right thing), but on a full frome camera, the hood actually obscures some of the image on the copy I got.
