Nikon previews pro-grade D4S camera with faster autofocusing

Nikon D4 DSLR

The D3300 isn't the only DSLR that Nikon will show at CES. The camera maker has revealed that it will preview its next-generation flagship camera, the D4S, at its booth on the show floor. While Nikon isn't saying much about the new pro cam's advantages over the D4, it's already talking up a new imaging engine that should deliver faster autofocusing -- no mean feat when the D4 is already quite nimble. It's still too early for any launch details, but you can be sure that we'll take a look at the D4S as soon as possible.
