Dear Forum Member,
My name is Nick Fan, the designer of this tripod foot and popular Nodal Ninja pano heads.
First of all, I would like to express my appreciation for Panoguy for contacting me to develop such a product. He has even sent me his Pentax tripod foot for reverse engineering at his own cost. I judge he is a very enthusiastic contributors in Pentax user community. At the beginning, the original lens ring clamp was not available separately. So I decided to give it a try knowing that this will be a very very small market. Later, I was informed of the availability of the original lens ring clamp.
But I have invested considerable time in it development and even bought a DA 60-250mm for testing my prototypes. I decided to refine (at a higher cost) the prototypes to the current state that I really fall in love with. The beauty of the rig is only revealed by mounting it on the lens. It forms a coherent part of the lens and looks much better than an add on Arca style plate on the tripod foot.
The items will be available by the end of May.
Thanks for your interest.
Nick
