This ergonomic Chrosziel Magnum 3-Axis 2-Channel Wireless Lens Control System controls up to 2x motors (not included), plus remotely controls standard lens encoder motors for true FIZ with the hand unit (focus & iris) and the zoom rocker (for adding zoom control). Dual band transmission is included with either GHz or MHz band options. Use the included spectrum analyzer on the unit to identify the best low interference transmission frequency.

MagNum Hand Unit

This remote lens control system was ergonomically and functionally optimized in cooperation with actual users. The Hand Unit features a smooth-turning handwheel with two variable mechanical stops (VariLock II), infinitely adjustable fluid damping (VariFluid) on the large scale wheel itself, plus mechanical locking device and the optional inclusion of scale discs or rings. It offers a contact-less, dust-proof slider bar with variable mechanical stops.

Secure your hold on the MagNum with a convenient finger grip on the rear of the unit. A hand strap and padded neck strap ares included for safety and comfort. 

Monitor and navigate the UI on the MagNum's OLED and its directional buttons/keys. You'll be happy to learn that the unit weighs only 1.27lb (approx. 577g) so you can operate this on long shoot days with ease. Using the user interface, you can view either imperial or metric when determining tape distances. For convenience, you can mount the MagNum on either side of the camera, because it offers both left and right hand support by reversing the OLED display.

Use the internal 2.4 GHz antenna or connect an external antenna to the BNC port. Be sure to make use of the spectrum analyzer included on the unit so you can select the ideal transmission frequency.

Make use of the mechanical lock on the focus wheel to prevent unwanted focus changes or the end (hard) stops on the wheel or iris slider for accurate focus pulls and iris changes. 

Chrosziel also states you can tie in a 2nd MagNum unit for second hand unit support.

Zoom Rocker

The Chrosziel Zoom Rocker (MN-ZR) combines mechanical step-less zooming for precise zoom control and contactless signal transmission reducing the risk of water, dust or dirt entering the MagNum Hand Unit. 

For maximum protection and best ergonomic use, the Zoom Rocker is mounted on the back of your MagNum Hand Unit (MN-200T). The Zoom Rocker is cable free and transmits the zoom signal without power consumption. The zoom speed is set by varying the angle of the rocker. Due to the use of latest CAD-optimized design, the rocker can be operated with one or two fingers. The MagNum Firmware integrates comfort functions like Zoom Speed, Zoom Zap, Software Zoom Limits, Zoom Soft Stop and Zoom Bar.

The Chrosziel Zoom Rocker is compatible with the MagNum Hand Unit (MN-150T sold separately and the included MN-200T), manufactured 2016 or newer. Older models of the MagNum Hand Unit MN-150T or MN-200T can be upgraded for compatibility (with the separate purchase of MN-ZR-UP).

NOTE: The MagNum Hand Unit MN-100T is NOT compatible with the Chrosziel Zoom Rocker.

Mounting Options

The MagNum provides multiple mounting options, including cold shoe or rod mounted support.

On any hot or cold shoe socket, the cold shoe bracket MN-RMB1 secures the MagNum receiver. Instead of the camera hot shoe socket, the receiver can be mounted laterally on Ø 15 and 19mm rods on the Quick- t 15/19mm MN-RMB2 with the cold shoe Connection. 

Alternatively, the articulating arm with ¼” screw threads 550-RA can be bolted directly to the Receiver or be removable mounted in combination with the cold shoe connector adapter 550-RABU to the cold shoe bracket MN-RMB1 of the MagNum Receiver. 

MagNum Kits & Optional Accessories

All kits include motor cables, a power cable with D-Tap connector (4-Pin XLR in MagNum Broadcast KIT) and a high-quality carrying case with foam insert. Optional accessories are available separately, including motors with gears 0.8 + 0.5 + 0.4 and a mounting clamp for Ø 19mm and 15mm rods. Third-party accessories are also available.

The optional Belt Holster (MN-HOL) attaches the Hand unit securely to your belt. This means the Focus assistant can safely perform without swinging off of the hand unit and the hand unit itself is close at hand.

Motors (sold separately)

For years, Chrosziel relied on the quality and the performance of the manufacturers Heden Engineering Co. and betz-tools GmbH for their motors. The motors of both manufacturers meet the following requirements: Digital motor with digital encoder, vertical, complete with gears 0.8 + 0.6 + 0.5 + 0.4 and bracket for mounting on Ø 19 rod and usage for Ø 15 rod.

TheChrosziel Digital Motor (CDM-100) was developed to be an extremely lightweight, silent, small, and horizontally-aligned lens motor. It suits many major photo, broadcast and cine lenses on the market. The CDM-100 is supplied in the kits for MagNum and Aladin and can be ordered separately.

MagNum is also compatible with other manufacturers such as ARRI CLM4, Indicam, Scorpio, Preston, RED Technica or similar digital encoder motors.
