The Sigma 50-500mm APO DG OS HSM F4.5-6.3 is Sigma's latest version of their 50-500mm superzoom lens, commonly known as the "Bigma". Introduced in February, 2010, it replaces the old 50-500mm F4-6.3 EX DG HSM and features a slightly modified optical formula, losing half a stop at the wide end in...
The first version of this lens earned the nickname Bigma for its 4.25-pound heft and huge size.Now comes Son of Bigma ($1,600, street), lighter at a little less than 4.2 pounds, yet with a number of optical improvements including image stabilization.Like the original, this 50–500mm boasts the...

Sharp at all focal lengths., Stunningly good bokeh, Good AF., Outstanding OS., Killer Range., 500mm handheld!, Lightweight (relatively speaking), Price
Only f/6.3 at the longest focal length, Still somewhat heavy when compared to say, the 300mm f/4. That said, you get a lot more reach with the Bigma OS., Some minor chromatic aberration, especially in high contrast situations, AF has trouble with cluttered shots (brush in front of the subject).
