ZEISS DigiMutar 1.4x Tele-Extender

With its precision-engineered optics and superior quality design, the Zeiss DigiMutar 1.4x Tele-Extender is a simple and cost-effective way to add focal length to your already existing 2/3" HD lenses. At less than an inch long and weighing under 15 ounces, the DigiMutar attaches behind your B4-mount lens and multiplies its reach by 1.4, losing only a single stop of light in the process.
