Nikon D4s vs D4: 10 Connectivity
Wi-Fi connectivity is becoming increasingly important, and the Nikon D4s uses the same WT-5 add-on wi-fi module as the D4. It’s expensive, but much smaller, simpler and more efficient than Nikon’s older WT-4 unit.
The difference between these two cameras lies in their Ethernet connection. Wi-Fi technology is what grabs the headlines, but it’s old-fashioned wired Ethernet that provides the speed.
Accredited sports photographers can use facilities not available to the public, and in many major venues this includes Ethernet connections.
The Nikon D4 supports 100 Base T Ethernet, but the D4s has a 10x faster 1000 Base T connection.
Nikon D4s vs D4: 11 Memory
There’s no change in the memory card formats. Like the D4, the Nikon D4s has dual card slots – one for Type 1 Compact Flash cards (it supports the latest UDMA 7 standard) and one for the new fast, high-capacity XQD format.
Currently only the Nikon D4 and D4s use this card format, so it remains to be seen if and when it will take off.
Nikon D4s vs D4: 12 Battery
The D4s uses an EN-EL18a variant of the EN-EL18 battery used in the Nikon D4. It brings an improved battery life of 3,020 shots (CIPA standard) compared to the 2,600 shots available on the D4.
Nikon reports roughly twice this life for both the D4 and D4s in its own continuous shooting tests.
