Re: focal point/plane

Thank you for your replies, looks like it's back to the drawing board!
Not patronising at all John, and a very interesting link. After reading
your comments I recalled reading an article, years ago, about the NP
for the 14-54 lens so I began trawling through many thousands of files
from three lap tops on the off chance that I downloaded the information.
I did and this is what I found:

14 80
18 74
25 62
35 51
54 35

Unfortunately, no reference to where to measure the NP from. This is
where you may be able to help Graham, any ideas?
