Standard 15mm rails are recommended for optimal use, which you should already have if you have a matte box. Your rails should not extend beyond the front of the lens. You will also need a medium/heavy duty tripod to support the front weight of the main box unit.

Yes, it has a standard 12VDC input using a 2.1mm barrel connector. You can purchase a D-tap cable from our site and power it from your camera. Note the kit ships with a mains PSU with long lead as standard.

The unit is about 1.5g.

The rail block on the main unit can be repositioned to ensure the lens is centred through the hole. There is about 50mm adjustment possible.

The ZeePrompt ships with a 16mm receiver adaptor. This screws onto the base of the unit which allows you to attach it to a standard lighting stand. The unit can then be positioned in front of the camera lens. Standard threaded 3/8th inch and 1/4 inch holes are on the base making it easy to mount on tripods and other grip.

You will lose less than 1 stop of light through the glass. This is not a problem for most cameras. The glass ‘warms up’ the image slightly, which can be corrected in post-production if necessary.

On a full-frame sensor, the widest focal length is approximately 28mm before the edges of the ZeePrompt are visible in the shot.

The opening at the back of the ZeePrompt (where the lens is positioned) is 140mm. Doughnuts are supplied to fit on various lenses.

The monitor is rated at 320nits which is more suited for indoor use. However, the enclosed design of the ZeePrompt ensures minimum external light enters the viewing area which means that it can be used outdoors in many cases.

While some teleprompter manufacturers provide distance tables, we don't, however we suggest anywhere between 4-8 metres. There are many factors to consider, such as how good the presenter's eyesight is, and how big the text is on screen.

The glass built into the unit and does not need to be removed during normal use. If it gets damaged, a replacement glass can be purchased from our website.

Make sure all dust and grit is brushed or washed from the glass. Do not rub it when dry. When clear of dust and grit, the surfaces may be cleaned using any soft cotton based cloth. Man-made fibres will eventually damage the surface. Dabbing the surface with a damp soapy cloth to remove dust and grit is safe. The glass can then be polished. Non-greasy window cleaning products used in conjunction with a cotton cloth should be safe, once all grit has been removed.
