I was to use the d-lux for qtvr and need the nodal point setting if anyone knows it.

I can't answer the question.

 

You might end up needing to speak with the lens designer if possible.

 

You should probably also specify both focal length and which nodal point (front or rear) since I suppose the two move with varying zoom. The nodal points would also move a very small amount depending on the focus point, but I'm sure you could neglect that.

 

For simplicity you might just choose the front plane of the body, assuming that it is near the rear nodal point, and call it done.

 

With luck there's someone on the forum who'll be so upset by this non-answer that he'll jump in with what you need.

 

Good luck!

Gary, there are numerous websites that explain in detail how to determine the nodal point of a given lens. (Just google nodal point lens)

For example this one: http://www.vrphotography.com/data/pages/techtutorials/technotes/nodalptalign-tn.html

 

Hope this helps.

Daniel,

 

Very good web site!

 

 

 

Gary,

 

I don't know where the nodal points of the DC-Vario-Summicron 7-22.5mm zoom lens might be located, but I think I know who might be able to help you: Andrew Nemeth of http://www.nemeng.com/. Andrew is an avid Leica enthusiast (like all of us) and is a member of this Leica forum. And he does quite a lot of (extraordinary!) QuickTime VR. If anyone can help you, it's him.

 

Good luck!
