Lately I had to realized a huge panoramic photo (59000x10000 px). I had to use my 70-200 2.8 at 200 and had some difficulties to find this bloody nodal point. Eventually I ended up with a very strange setting : I had to turn the upper arm frontward and set my lens at 148. The nodal point was behind my camera.
With this kind of setting I see 2 issues :
- There is no possibility to use a camera with grip since the plate is on the lens ;
- All the weight is concentrated at the end of the upper arm and the NN is not stiff enought to cope with this.
