This lens is reasonably good and sharp but there are some better ones out there if you want to spend a little more money. When attached to a zoom lens your widest setting will give a circular 180 degree fisheye image with a black background, but not quite as fisheye-ish as some other lenses. Zoom in until the circle fills the frame. Set the focus at infinity and you will probably not need to refocus because the depth of field is large. Zooming in further will produce a more rectangular image. F stop will not be effected. Overall a good value if you occasionally need a fisheye, but if you use it a lot I would go for a better one. Be carefully when handling, you cannot use a filter and the glass prottrudes Beyond the barrel.
