Funhouse of a lens for dramatic effect. Allows shots likely impossible with most other lenses. Not a low-light lens - don't even think about it. Unmatched for carshow, airshow, nature shots where wide is what you want. long end fairly sharp.
Wiiiiide; Great for confined spaces; Amazing perspective in right circumstance; Reasonably priced, considering; Long end fairly sharp
Easy to shoot your feet accidentally; Forget using it in low light; Distortion at periphery at 8mm but what would you expect Not FX; Funky lens cap thingie
