Overcoming some of the limitations of a D600

Young people today are so spoiled. Back in the '70's, '80's, and '90's in the days of film, plenty of photographers did fabulous work with the Nikon F2 and F3, both of which featured only a max 1/2000th speed shutter, and only 1/80th sec flash sync.

Very difficult for old photographers like myself to fret over petty issues like these.

The D600 does support Nikon's Auto FP feature in their Speedlight flashes. Although using Auto FP to get faster shutter speeds with flash does reduce your flash range significantly, it still can be effective in providing fill flash in bright settings. Refer to pages 234 and 235 of the Nikon D600 USA manual.
