The VariZoom VZROCK-J600 JVC Zoom/Focus/Iris Control is specifically designed for the JVC GY-HM600 and GY-HM650 cameras. The zoom rocker has a wide range of motion for a fine degree of speed control. The VZROCK-J600 features a dedicated rocker-style focus button, a low-profile record/pause button, iris control buttons, and an LED for indicating recording status. Additional features include buttons for selecting auto or manual focus and iris modes and a button for turning on-screen displays on and off.

The farther you press the zoom rocker switch to the right the faster it will zoom in (telephoto), and the farther you press it to the left the faster it will zoom out (wide).

You can also control the focus of your lens manually using the controller. You must first set the camera to "Manual Focus" mode. Once you are in Manual Focus mode, you can use the switch on the controller marked "FOCUS" to precisely adjust the focal plane. Pressing the up-arrow will move the focal plane farther away while pressing the down-arrow will bring the focal plane closer. The available focal range will be somewhat reduced at telephoto.

The small button marked with a red "R" is the record start/stop button.

The F- and F+ buttons control the iris setting. The F- button will lower the f-stop (open iris) while the F+ button will raise the f-stop (close iris) between 1.8 and 8.0 (range will differ at telephoto).

The LED indicator light will turn on and off to indicate recording status.

The "On" button toggles between auto and manual iris mode, and the "A" button toggles between auto and manual focus mode.

The Data button toggles the on-screen display (record time, settings, etc.) on and off.

Q: 4. how to adjust?

A: 1) adjust the position of the rocker control on the tripod grip by loosening the brass nuts then retighten the nuts when the rocker control is where desired on the tripods arm.2) Zoom adjustment is by pressing the tab of the rocker down to right or left. Zooms in or out depending on which side you press on the rocker tab. Press lightly gives slow zoom or more pressure to zoom in/out quicker.3) I haven't attempted to adjust the speed at which that the rocker tab come from the factory.It is a nice unit much better than using the controls on the video camera. After the first time I used a friends I went out and pick this one up.Hope this helps

Q: 5. Will this work with the Sony A7R III if used with a LANC to AV-R adapter, and an AV-R to Multi Terminal adapter? (IE: Manfrotto 522AV & Sony VMC-AVM1)

A: No, it is not compatible.

Q: 6. I see reviews that say this works with the Sony AX100. How? There isn't a LANC jack and I haven't been able to find an adapter.

A: You can use this controller with the AX100, however you would need to get two adapters for it. First you would need a LANC to A/V R adapter and then an A/V R to Multi Terminal adapter. If you wanted to avoid using adapters Sony makes the RM-VPR1 controller which is very nice and simple.
