Note: The NT4 is a heavy mic, and Rycote does not recommend mounting it on a camera hot shoe since it could damage the housing. If you do choose to go ahead with this, please see the information below.
Our recommended shock mount for the NT4 is the InVision INV-BH. This is suitable for microphones between 19 and 34mm in diameter, and up to 500g in weight / 500mm in length. Relevant product details (including order codes) can be found here:
A 3/8" hot shoe adapter will also be required to use the mount:
