This is made for the "Samyang 8mm" fisheye lens. It does not matter what camera the lens is on, the pivot points are located over the npp/lpp/osp point of the lens, and mounted to the lens itself. While there are methods for using string and a plumb bob to shoot panos, they do not pivot accurately around the npp. I believe this is the first use of a pivot and yoke to suspend the plumb bob accurately from the npp. Of course this is only as accurate as the operator. I had no problems and I made sure to include foreground and background items in the scenes. I got very good stitches. I have left the few minor errors that were present. I have made some revisions to the parts in the link. I have reduced the yoke width to 1/2 its current width. This will make the white square at the nadir(straight down) 1/4 of what it is now. I also modified the way the string is attached to allow for multiple heights without re-tieing. Unfortunately...I had this set printed in WSF as a test print, with the intention of printing them in GR. I did get one set ordered in GR before it was discontinued, I hope they work as well as the WSF. My very first handheld pano with the "Pan-NO-head" is here along with pictures of how it's mounted and operated. The Pano-NO-head My next two test panos, Rainforest house at the zoo from the mezzanine Rainforest house at the zoo feedback is always welcome. bvr ps. Hey Shapeways, can I come shoot an interactive panorama of the production facility in NY with parts that were made there?
