While the second card slot and slightly improved performance are welcome upgrades to an already brilliant camera, the new video recording mode and live monitor view are a bit disappointing compared to other premium models. The D300s is still utterly superb and one of the best DSLRs on the market, but don't trade in your D300 just yet.
And so the D300s marks a neat upgrade to the D300, but the £1499.99 price tag might mean you think twice about upgrading. Because, if you already own the D300, then unless you desperately need the HD video capability, the slightly improved frame rate or the stereo audio capability, then the D300 would probably be perfectly adequate. If you’re buying into the Nikon DX system for the first time, or are trading up anyway, then on balance, the extra couple of hundred quid (the D300 popularity means it still retails for around £1300, though you’ll find it for less by shopping around) might make sense.
The Nikon D300s updates the excellent D300 as Nikon’s flagship DX format DSLR. While superficially very similar to the D300, there are major additions “borrowed” from other models such as the virtual horizon system introduced on the D3 and HD movie capture from Nikon’s D90.
Another stunning new Nikon DX format DSLR that combines the performance and handling panache of its predecessor with HD video and other neat toys that may just make it worth your reaching for your cheque book.
