"MC" has it right (and also see "z's" post, below). You

may prefer a wide-angle lens with considerable barrel

"distortion" to minimize extreme WA effects with rounded

subjects (though this will not "correct" too-close

a viewpoint...). For more on why even a moderate WA lens

with no "distortion" can make people look bad, and a

VERY much wider fisheye can show people near the edges

looking "OK", see:

www.David-Ruether-Photography.com/articles.html#perspective and

www.David-Ruether-Photography.com/perspective-correction.htm.

BTW, the WA "distortion" appearance is due to the

perspective difference between the perspective type of

most lenses and the perspective type of our vision,

which is closer to "fisheye"...
