Expand the wide-angle capabilities of your portable servo zoom lens with this 0.7x Wide Attachment from Fujinon. The attachment mounts onto the front of your portable servo lens with a 85mm front diameter and magnifies the wide end of your lens by 0.7x. The converter maintains the original f-stop of the lens, does not allow zooming, and focus is possible with the macro lever on the lens. It is compatible with UA18x7.6, HA18x7.6, and ZA17x7.6 model lenses.
