Thought this link may be of interest for the pockect cam crowd with the smaller lens. These seem to be high quality extremely small wide lenses - 0.25 - 0.3 - 0.45
. Ive never used one just stumbled on to the site.

Interesting Matt. Problem is the shot of the vehicle does little to tell you how much these lenses distort. Of course I expect distortion at these very short focal lengths, But a picture containing some straight lines woul've been useful (but perhaps off-putting from a sales point of view).
