The Hensoldt / Zeiss ZF 6-24x72mm has a monstrous 72mm objective and is probably the largest objective high end riflescope of all time. It features some of the highest optical performance of any scope ever made, period. That includes any modern scope including Schmidt's, Tangent Theta, Vortex, Nightforce, ZCO, USO, Kahles, IOR, etc, etc. Biggest and brightest eyebox, wonderfully bright image, and top shelf sharpness, contrast, and resolution.

This is an honest in depth review showing the good (optical quality) and the bad (lack of usefulness as a tactical scope).

This is a rare scope and didn't make much of a splash in the market, but it's a solid ELR and target scope. Still available from Hensoldt for the last 15 years. The miniature Hubbel.
