no data for your camera. But some data for your lens

fl-------Entrance Pupil to sensor plane
14-----97
18-----91
25-----79
35-----68
54-----52


sensor plane is marked on the camera body. Hope it helps.

Nick Fan,

Thanx for your reply.

I think I can use this to find the right position.

Of course if there is anyone else who has the exact settings I will still be appreciative of them.....

Hey Nick

Regarding the entrance pupil to sensor plane numbers - I'm in doubt how to use them? Should I place my sensor plane a 52 mm when using 54 mm fl?

Hi Caver,

you have to adjust your focus length and then measure from the sensor plane to the front of your lens. For fl 54 you should find it in a distance from 52 mm from the sensor plane. You can mark this point on your lens and then you have to bring it on top of the turning point of the Nodal Ninja. Start with a longer distance like 54 and move the camera to the points from that point bringing the camera forward. So you always know, you come only from one side, from behind to the nnp.

I use two post behind each other, the camera lined up with them. First shot straight on, turn to the left that you just can sea the posts, second shot, turn to the right in the same manner, third shot. If the post in front does not move to right or left in relation to the post at the back, you have found your nnp for the focal length.

Success and enjoy

I'm still not sure because if it's the front of the lens the distance from the sensor plane (the sensor plane is a fixed point when compared to the lens front) to the front of the lens increases but according to the table it decreases.

I know I can find the points on my own but then these tables have no point in being here :wink:

Just to clairfy with another example from the table:

At a focal length of 25mm, the entrance pupil is 79mm in front of the sensor plane.

You need to position the camera such that the point 79mm in front of the sensor and on the central axis of the lens is positioned in line with the horizontal and vertical axes of rotation of the panorama head. Where the front of the lens happens to be is of no interest.
