Details

## Environment :
1/18/2013 nightly build
unagi

## Repro :
1. go out in the snow
2. go into a building that is warm
3. take a picture, holding the camera still for about 10 seconds.

## Expected :
The picture will be in focus

## Actual :
The picture may be out of focus because the zoom level acts too slow and takes a picture while it's still focusing.

## Note :
1. Probably could use the freezer or fridge to repro this...
2. is there a way to detect that the focusing is completed before taking a picture?  Also it seems like a performance issue that the zoom takes so long...

Regarding note 2: the picture taking process is closed-loop: the camera app waits for the camera driver to report either auto-focus success or failure, and only then takes a picture.

If your lense is foggy (as it would be in moving from a very cold environment to a warm and moist one), this will affect the camera's ability to auto-focus.
this is all hardware -> wontfix
