Nikon D800 vs D4s
Nikon D800 £1999, $2999
The D4s is built for action, and can fire off a sequence at a phenomenal 11 frames per second. The D800 has a maximum continuous shooting rate of 4fps.
The D4s can shoot up to 176 RAW files before its buffer is full; the D800 pulls up after a 25-NEF sequence.
The D800 has a groundbreaking 36-megapixel sensor, compared to a 16MP chip in the D4s. Both have anti-aliasing filters. If you want more sharpness, the D800’s twin (the D800e) dispenses with the filter.
A vertical grip with extra battery capacity is an optional extra with the D800 (costing £285/$370) but is built in with the D4s.
Maximum expanded ISO setting on the D4s sets a new record, topping out at ISO409600. The D800 can be pushed up to ISO25600
The D4s can use the ultra-compact WT-5 wireless transmitter to send pictures to a computer, or its ultra-high-speed Ethernet port. The D800 uses the clunkier, older WT-4 wireless transmitter.
