The Nikon D300 made quite an impact when it was first launched - enough to prompt us to conclude: 'There's simply no better semi-professional digital SLR on the market.' And, in many respects, it is still the camera to beat in that class - nearly two years later and it is still able to command essentially the same price as at launch (though the strong Yen has pushed all prices up). And this success appears to have left Nikon unsure how to improve on its APS-C flagship.

Although the many of the additions to the D300S are simply those that we've seen appear on Nikons since the D300 arrived (virtual horizon from the D3, movies from the D90), one genuinely new feature is the inclusion of contrast-detection autofocus that operates while in movie mode - a first for a Nikon DSLR. It's not the quickest focusing you'll ever see, though, and you'll also need to make use of the external mic socket if you're to avoid the distant generator chuntering or asthmatic rodent sounds that autofocus motors seem to so accurately mimic.

The D300S inherits the non-latched memory card door we first saw on the D700, but now with both a CF and SD slot behind it. As you'd expect at this level, the exact behaviour of how the camera writes to the two cards can be defined: use one after the other, write backups to the second card, RAW and JPEG to different cards or split stills and videos. In fact many of the changes make the D300S even more similar to the D700, including Nikon's now-standard multi controller with separate central button that, on this camera, initiates movie recording when in live view.

The continuous shooting speed has been given a bit of a boost, with the camera now capable of shooting at 7fps using its own battery and 8fps with the MB-D10 battery grip. The settings display screen is now, in line with most current DSLRs, interactive, allowing most shooting settings to be changed more quickly, a couple of extra Active D-Lighting options ('Auto' and 'Extra High') have been thrown in too. Finally the 'Quiet' drive mode first seen on the D5000 also makes an appearance.

However the arrival of the distinctly pro-targetted Canon EOS 7D and the accomplished but more wallet-friendly Pentax K-7 could make Nikon's gentle refresh of the D300 look insufficient. (Due to the similarities between the two cameras, some product images come from the D300 review)
