This cable requires a separately available Promote Control HDR bracketing controller unit.

Using a separate shutter cable with Promote Control offers the following benefits:

• Enables Bulb Ramping mode
• Provides Mirror Lock-Up functionality
• Allows automated exposures longer than 30 seconds
• Ensures faster camera reaction to shutter release, especially in "High Dynamic Range" mode
• Activates "Manual Hold" mode
• Enables arbitrary shutter speeds in "One Shot" and "Time Lapse" modes
• Allows pre-focusing the camera using the Promote Control "Focus" button
• Enables basic Promote Control shutter release functionality even when out of battery power

This shutter cable is compatible with the following cameras:

Nikon D4, D4s, D3, D3s, D3X, D2X, D2Xs, D2Hs, D2H, D200, D300, D300s, D500, D700, D800.

* Promote Control firmware update 2.49b or later is required for Nikon D800.
