Expand the wide-angle capabilities of your portable servo zoom lens with this Fisheye Attachment from Fujinon. The attachment mounts onto the front of your portable servo lens with an 85mm front diameter and magnifies only the wide end of your lens by 0.55x. The converter maintains the original f/ number of the lens, does not allow zoom, and focus can only be adjusted using the manual macro focus lever. It is compatible with UA18x7.6, HA18x7.6, and ZA17x7.6 model lenses.
