At the end of July, 2009, Nikon gave the D300 a makeover to bring it up to date with some of the latest technologies. Upgrades included the now obligatory HD movie mode, but this time with a contrast based AF system. (The D90 and D5000 use manual focus only in their movie modes). It also now has dual memory card slots for SD and Compact Flash cards. It inherits a virtual horizon indicator from the D3, has a tweaked D-Lighting system, a quiet shutter release mode, and a 7 frame per second shot rate. The changes may not tempt some D300 owners to upgrade, but D90 owners, and entry-level DSLR owners, will be looking to this as their next big camera upgrade. And maybe you will too, because the D300s is one of the best Nikon DSLR cameras.
