Re: G1 nodal point measured

Hi Lawrence,

the question is, which nodal point Harry ment ... the wide-angle or the tele.

The tele seems to be right ... the wide-angle could be incorrect yes ... it's harder to check than tele because of the barrel distortion.

I'll do further tests at the weekend.

Greetings from Germany

So, is Harry right? Is the nodal point measurement wrong? I have a
picture of the diagram but I don't know whether to believe the
measurements on it...
