This is the most obvious physical difference between the Nikon D600 vs D800. The D800 is 123mm high, while the D600 is 10mm shorter at 113mm. Part of this is due to the lower overall body height, and partly the low-profile pentaprism, which Nikon assures us is a true prism and not a pentamirror, and which still offers a 100 percent field of view.
The D600 follows the design of the D7000, using magnesium alloy for the top and back panels but polycarbonate elsewhere. The D800, by contrast, has an all-metal chassis. We can expect the D600 to be resilient, but the D800 to be more resilient still!
7. Memory card slots
Nikon was cautious with the D800, providing both Compact Flash and SD card slots. This ensures a degree of compatibility with older professional Nikon D-SLRs, but in the longer term it’s a serious compromise because in order to use both card slots, photographers will have to carry two types of card. With the D600, Nikon bit the bullet and swapped to twin SD card slots, which – in our view – is a strong advantage. Both slots are compatible with the fastest UHS-1 SDHC and SDXC cards
8. Wi-fi connectivity
Oddly, the D800 was not made compatible with the WT-5 wi-fi transmitter launched alongside the D4. The only alternative is the old and cumbersome WT-4a. The D600, however, has a low-cost WU-1b transmitter which connects the camera to a smart phone or tablet for basic camera control, live view and photo uploads. That’s a big plus point for the D600 – particularly as this only costs £65$60 or less (and not £500/$700 plus, as for the WT-4a or WT-5).
