It would be good to have everyone enter there values for their Nodal Point / Entrance Pupil for lens and camera combinations.

Some searching on the web will find a lot of people saying they want to start to create a database of some kind, but have not seen anything substantial so far (correct me if I am wrong).

Hopefully the effort of creating this Wiki, will boost the creation of this list.

The following definitions have been used

x distance between the middle of the tripod mount to the plane of the entrance pupil
y distance between the middle of the tripod mount to the plane of the middle of the lens
z distance between the the middle of the tripod mount to the centre of the lens (0 if the tripod mount is over the centre of the lens) This should only be dependent on the camera body


Please fill in the x, y and z values you have found for your camera / lens / focal length combination. Be careful if you are using extensions. These could offset the postion of your camera, and make the reading on your panorama head incorrect. Use as much as possible actual measurements rather than the reading on your panorama head, unless your are sure these are the same.
