Remotely control your lens's focus with Chrosziel's MN-150 MagNum Extendable Wireless Lens Control System. This system includes Chrosziel's upgradeable MagNum transmitter and receiver as well as the necessary power and cabling accessories to use the unit right out of the box. The only thing you need to add is a motor. The MagNum unit is compatible with motors that use a 7-pin LEMO interface.

For easy operation, calibration is automatic with lenses that have hard stops. If you use stills lenses that don't have stops at close focus and infinity, a special calibration mode allows you to manually calibrate the focusing distance. To adjust the settings on the MagNum, an OLED screen and directional buttons provide an intuitive interface. Record start/stop can be controlled from the hand unit if the camera is connected to the receiver.

The hand unit is upgradeable for a second degree of lens control. The upgrade kit is separately available and adds a sliding control and a marking stripe to the left side of the transmitter.
