Control focus with absolute precision on virtually any lens with VariZoom's new touchscreen wireless follow focus. This cutting-edge lens drive system is built using advanced control electronics, software and mechanical design that define a new price-performance standard. All parameters adjust quickly with our clean, logical GUI and our powerful motor system auto-calibrates for hassle-free setup. This 1-channel TOC (Total Optical Control) package easily upgrades to a 2- or 3-channel system, and it can be connected by cable for hostile RFI environments.

Note: One receiver power cable included at no extra charge, but customer must specify the needed cable type (XLR, D-tap, etc.)

The VariZoom TOC-F1 wireless follow focus system brings cinema grade lens control into the realm of the affordable-to-own. This powerful, intuitive system will pay for itself quickly and expand the capabilities of your productions. Although the price is relatively low, no corners were cut in the manufacture and design of the system. Expensive motor cores are painstakingly assembled into our zero backlash proprietary drive system, resulting in a smooth, quiet, highly dynamic operational range that will creep or blast off with equal grace. The compact receiver/motor driver is, on the surface, a no-frills black box, but deep down it's the transparent heart of the system, as it must execute all motor commands with unerring precision and authority.

The highly intuitive touchscreen-controlled hand unit is loaded with features that make it easy to use and powerful in operation. The custom machined fluid-drag focus knob is incredibly robust but delicate in action. A defeatable LED backlight ensures you'll always be able to hit the marks regardless of lighting, while the backing software allows great flexibility in setting the range and sensitivity of the knob response. The iris slider serves as an optional focus input for specific applications, but more fittingly it is already included if you ever decide to upgrade to a 2-channel focus/iris package.

The entire system fits into a compact, waterproof hard case that will take just about anything you can throw at it, while our 2-year warranty and exceptional customer support offer peace of mind.
