29x Continuous Zoom

This product was an OptroMech innovation, and created under ‘joint-development’ with one of our partners. Our idea was simple: let’s go to a higher f/#, and increase the zoom ratio as much as possible – without exceeding the mechanical dimensions of the popular 15-300mm lens (the ZIV lens, named after it’s designer – OptroMech’s owner).
so instead of 20x – we got 29x, with 7 elements and amazing mechanics.
