Eiki AH AV24010

The Eiki AH-AV24010 is a long-throw manual-zoom projection lens for Eiki's large-venue interchangeable-lens projectors. It is the lens to reach for when the projector must sit well back from the screen, as in a deep auditorium or a rear-of-house rigging position, and still fill the image edge to edge.

Zoom and focus are set manually at the lens, a common trade-off on long optics where the priority is reach and image sharpness over motorized convenience. It installs through the projector's interchangeable lens opening and carries an aperture of f/1.84 to f/2.58 across the zoom range.
