Entrance Pupil Database

Wouldn't it be great if everyone entered their values for their NPP / 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).

Please enter your own values if they are not listed.

To cater for all the different camera bodies and lenses, the tables have been split into 3 parts:

• The first table shows the position of the tripod mount in relation to the lens axis. This is easy to measure and is dependent only on the camera body.
• The second table shows the actual entrance pupil distance which is only dependent on the lens itself. Note that the NPP for fisheye lenses is not constant over the image circle's FoV, so you will sometimes find different NPP values depending on the angle where your images overlap.
• The third table shows the number if pics neccessay for a full 360° coverage and the rotation angle between shots.

Use as much as possible actual measurements rather than the reading on your panorama head, unless your are sure these are the same.

To enter a line for your combination, edit the page by clicking edit at the top of the screen (you may need to create an account or sign-in first), and edit the table below.

Enter the exact lens name, or if you are using a camera with a fixed lens the name of your camera as mentioned at dpreview.		Facing the side of the lens, the distance from the base of the lens to the Entrance Pupil. A negative value means the entrance pupil is before the lens base.

<Manufacturer / Lens>	<Focal Length>	<Entrance Pupil Length>

• To calculate the Entrance pupil distance add the Tripod Mount Length (L1) from the camera and the Entrance Pupil Length (L2) from the lens. So for example for a Canon 300d and a 10-22mm at 10mm, the total Entrance pupil distance from the tripod mount is 40mm + 66mm = 106mm

• For these Focal Length values the actual focus is set to infinity ($\infty$)
