Dustin Abbott completed his exhaustive review of the Sigma 500mm F/4 OS Sport lens.

From his conclusion:

The Sigma 500mm F/4 OS HSM Sport is a unique lens.  It’s a third party option competing in a space dominated by first party lenses.  It’s an expensive lens that doubles as a relative value.

The size, weight, and expense of a lens like the 500S makes it clear that it isn’t for everyone.  Lenses like this take a lot of skill to use well (and strength, too, if you try to handhold it).  A lens like the Sigma 60-600mm OS Sport is going to be more affordable and versatile, and, if you have a tight budget, a lens like the Sigma 150-600mm OS C can give you some incredible images for under a thousand bucks.  But there’s no question that the 500S gives you a different kind of versatility.  The ability to shoot in more lighting situations with both better autofocus performance and image quality.  The ability to get incredible subject isolation.  And, when adding teleconverters to the mix, an incredible amount of reach while retaining autofocus ability.
