CARL ZEISS SHARPMAX™

The Zeiss Sharp Max™ Universal is the most precise field instrument ever made to adjust and align back-focus on both standard definition and high definition B4 mount lenses. With Sharp Max™ Universal there’s no need to light a chart or move the camera. First, the lens is set to its infinity mark with the iris wide open. Next, Sharp Max™ Universal is held up to the front of the shooting lens and the power button is pressed. Finally, the back-focus ring is adjusted for the finest focus in the center of the internal back lit Siemens star and the back-focus ring is locked. That’s it! Infinity focus is set and the focus scales are accurately calibrated.

Weighing only 2.2 lbs. (1 kg), with a size of just 83.5mm in diameter by 280mm long, the Sharp Max™ Universal should be part of every camera package. A set of nine adapter rings ranging from 80mm to 130mm ensure that Sharp Max™ Universal will work with nearly all lenses available in B4 mount.
