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.

Ergonomic Handheld Transmitter

Compact in size, the transmitter has a rounded handle with a finger grip on the rear so you can hold it securely while operating. The transmitter houses an internal 2.4 GHz antenna and has a BNC spigot that will accept an external 434 MHz antenna. The focus knob has a brake and adjustable hard-stops for repeatable focus pulls. The hand unit has an integrated spectrum analyzer that can determine the best frequency for transmission.

Dual-Channel Receiver

With dual outputs, the receiver can drive up to two motors that connect via 7-pin LEMO. The receiver is capable of calibrating motors to the lens without the aid of the transmitter. When connected to a camera via the serial output, start/stop can be remotely controlled from the transmitter.

Hardware Upgradeable

A separately available upgrade module can be installed for controlling a second lens parameter. When installed, the hand controller will gain a sliding adjustment encoder with a marking stripe that can be operated with your left hand.
