Mate, a couple of points I will raise on the Kaidan products.
- The Quickpan (Camera Specific) CS III Panoheads are pretty much a no brainier to set up (Pre-worked out nodal point)
- The Professional Twin Axis brackets are not so easy to set up. (Not even a guess at the nodal point)
It would seem after the success of the Coolpix 9XX series and the Kiwi Brackets things were all pretty easy. Then came the CP4500 and things needed to be re-thought and thus the Quickpan CS III Panoheads came along. All the while the "Manual Adjusting" Twin Axis existed for those who needed to connect a SLR camera or DSLR and was targeted at the serious professional photographer with plenty of knowledge in finding nodal points etc. Then all of a sudden the Coolpix 5000/5400/8700 came along using an ugly large adaptor and the later two a new FC-E9 Fisheye instead of the more compact CP9XX-4500 FC-E8 versions and rather then re-inventing the wheel and making a totally new bracket they have just palmed the professional "Twin Axis" bracket on to these owners without any thought to the newbies. Giving no indication to the nodal point settings. Not replying to your email is poor! No excuses there, but the point I make is that nobody there probably has the answer to your question. If they did then this could be easily added to there website FAQ's.
All that said the products of Kaidan's are of good high quality.
One last point to all newbies, it is always better to ask questions on the forums before spending your cash! It is a well beaten path and most of us are willing to help and save you from the pitfalls.
