In addition, your 16-85 is a header in DX format, and cannot be used on D700. Only 50mm and 85mm headers can be used, which makes the wedding very inconvenient.
Furthermore, for a half frame, because X 1.5 is required, for an 85mm lens, it is more advantageous outdoors.
If the landlord wants to get on the D700, he has to follow a 24-70mm f2.8, and 30,000 can't fight. Because I heard that all 24- 120mm production was stopped.
It is recommended to use D300s, which is enough.
