It was hard to get a free moment at the Nikon booth here at WPPI due to all the interest in the new D4 and D800 cameras. When the crowds died down a little bit yesterday, I was fortunate to get a chance to speak with Steve Heiner, a Senior Technical Manager for Nikon. We talked a little bit about the new metering system in the D4/D800 and how major improvements have been made on an already incredible system. As Steve mentions, Nikon's Matrix metering has long been regarded as one of the best in the business. Even though the D3/D700 are great cameras (I've owned both in the past so I can personally vouch for them), Nikon was really lagging behind in the HD SLR market, but finally we now have two incredible movie making machines. Here is Steve talking about the D800/D4's upgraded metering system and some of the new features on both cameras that you may not know about. -MZ
