Nodal point of lenses?

You might want to ask in the Nikon lens forum at DPReview; one participant there, Joe Wisniewski has collected a lot of data about Nikon lenses such as nodal point measurements.

When you say trial and error, are you referring to the method by which you adjust the pivot point until 2 vertical edges (eg dor frames) one close and one farther out cease to move relative to one another?  That had been the recommendation I've most often seen rather than trying to get stats - also with sme zooms, it will vary depending on the fl.

Nodal point of lenses?

Dear all,

I am currently considering doing panorama with with Nikkor 17-35 AF-S and am looking for accurate information on the location of the Nodal point of the lens at different focal lenghts.

I am aware that it is possible to measure this by trial and error, but it would be faster to get that information immediately.

Thank you for any info you might have.

Best regards,
Bernard

Tim,
The only way as far as I'm concerned is to do it the way you've described, especially if you're using a zoom lens.

Manfrotto have some intructions available by going to www.bogenimaging.us/       Once at the website, select Manfrotto, then select "Heads...QTVR" then select any one of the QTVR heads "303" for example then once in, scroll down to the line "Click here to learn more about the exciting advantages of Pano / VR photography from Manfrotto's new site" (it is just above the specifications)

Gee whiz, I'll get this right hopefully sooner than later.  Continued from last post!
Then go to the instruction manual which is in a pdf format.
Hope this helps,
