Nikon D4s Key facts
An upgrade from the D4’s, this new sensor is designed to give faster data output, better dynamic range and reduced image noise at high ISOs. The improvement in high-ISO image quality is enhanced by the EXPEED 4 processor, although the megapixel count remains the same, at 16.2.
An updated edition of the 51-point MultiCAM 3500 AF module ensures super-fast autofocus acquisition. The new Group Area AF is particularly useful, enabling continuous AF to track fast-moving objects even when used in conjunction with the ultra-rapid maximum drive rate.
The 11 frames per second maximum burst rate is actually no faster than on the D4, but the D4s makes autofocus and metering possible on a frame-to-frame basis, even at this super-fast speed. It’s a bonus when tracking fast-moving targets.
One similarity to the D810 comes in the shape of the 91000-pixel 3D Colour Matrix III metering module. Live View metering options include full-time face recognition complete with subject tracking, for better results when shooting sequences of stills or movies.
Built to withstand the most demanding conditions, the durable magnesium alloy body is fully weather sealed. It’s a hefty beast, weighing in at 1.35 kilograms, but its size and weight are similar to that of, say, a D810 body with an additional MBD12 battery/vertical grip fitted
Need to know
To enable the rapid continuous shooting speed and smooth image quality at high ISOs, there has to be a sacrifice. Barring the elderly 12.3-megapixel D90 and D300s DX-format cameras, the D4s and D4 share the lowest megapixel count of any current Nikon D-SLR, along with the Df.
