I looked thru a Zeiss 20X60 IS Binocular or maybe the front Lenses were even bigger like 80 mm . It was many years ago like maybe 30 and details are pretty foggy . It was at a Sportsmans Fair at a Zeiss Factory Exhibit . All I can remember is that looking thru 20X while hand holding that huge Monster was startling . The Image Stabilization can be mechanical or electrical , and I think the Zeiss was mechanical .... no matter ....it really worked ! I have never seen another , and if I saw one for Sale at a reasonable price , I would have bought it . I bought a Canon IS but as yet have not taken it for Pdog hunting which is its main purpose .
