Jacobson Blimp for the F2
Nikon makes a generic soft leatherette blimp case, CS-13, to reduce the motor drive sound but it's hardly effective.

The Jacobson sound blimps, however, can reduce the sound level by 25dBs, and that's about 20 times quieter. They are not cheap, about $1000 new, but they can be hired for about $25 per day. It's perfect for weddings, on film sets etc, when any loud noise is prohibited.

The Blimp Case, type F2/DP-F, below is dedicated for the Nikon F2.
