HTML5: get device camera information (focal length,...)

Question

Is it somehow possible, in javascript, to retrieve technical information about the device camera, such as focal length?

NB: my goal is not to extract EXIF tags from an existing file (like in Read meta data from image file with javascript) but to find information about the current device camera.

Coming to a Firefox browser near you (apparently in version 39):

https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/enumerateDevices.

The MediaDevices.enumeratedDevices() method collects information about the media input and output devices available on the system.

Doesn't look like it will contain the information you want, but potentially will be available in the future. W3C Editors Draft.
