The Chrosziel MN-200 MagNum Dual Channel Wireless Lens Control System combines a receiver and a handheld transmitter unit for remote control of focus, iris, and camera record start/stop. The dual channel system operates at either the 2.4GHz or 430MHz frequency bands, offering five selectable channels in the 430 MHz band, and eleven channels in the 2.4GHz frequency band for interference-free operation. The receiver has ports that accept optional lens control cables, camera start/stop cables, and power cables. The system is compatible with optional lens motors, as well as wired analog zoom controls.

The hand unit features an ergonomically shaped handgrip and finger rest for comfortable operation, menu-guided intuitive handling through membrane keys, and a color OLED display. For focus control, a fluid-dampened hand wheel is provided, which spreads the focus range of any lens to one full turn of the wheel. Focus marks can be made on the marking disc, with two freely adjustable end stops also available. In addition to the focus wheel, the hand unit has a slide control for adjusting camera iris with extendable aluminum iris scales and adjustable end stops. Five 1/4"-20 mounting holes on the hand unit let you mount it to tripods stands, or even attach monitors. It is powered using Sony NP-FM50 type batteries.
