When the D3s was introduced at the very end of 2009, we took the rare step of giving it a POP award before running it through our Test Lab. The reason: The D3s was the first camera to break through the ISO 100,000 barrier. Combined with the proven low-light autofocus it inherited from its predecessor, the D3, we knew this would be the ultimate rig for the low-light shooter, not to mention the action shooter craving its 9-fps burst rate for highest-quality JPEGs. In our February 2010 test, it proved to be everything we expected, and more. Its nomination for 2010 Camera of the Year was a no-brainer.
