hi! Some know the nodal point of a Nikkor 17-55 2.8f and one Nikkor 70-200 2.8?

Regards!

The point will move with the zoom level.

There are some results here which might give you a starting point – http://wiki.panotools.org/Entrance_Pupil_Database.

Easiest way is to measure it yourself by lining up a near object with something distant. Set the required zoom then swing the camera from side to side and see how the objects move. Slide the camera backwards or forwards until there is no visible relative movement.

This is accurate enough for most panos.

Thanks but nobody know the configuration of the gigapan rulz fon one Nikkor 70-200 2.8f in 200mm? Or of the Nikkor 17-55 2.8f in 55 mm?

Nobody use one Epic Pro And a Nikkor 70-200??

Maybe this will be good for other users. This is the configuration for the Nikon lens in a Gigapan Epic Pro whit a Nikon D300s:

Nikon 70-200 2.8f VR = All the range need to move the rail to the number 85. In the Gigapan Epic Pro Lens Configuration FOV 4.1

Nikon 17-55 2.8f = In 55mm to 35mm move the rail to the number 104. In 17mm move the rail to the number 117.
In the Gigapan Epic Pro Lens Configuration FOV 46.7

This was so secret o complicate?… Community my friends… community.

Hope this will help other users.

Sorry for my bad english.

Regards!
