P3D Re: Belplasca Focus

[Bob Wier <wier@xxxxxxxxxxxxxxxxx>]

|Does anybody know how to adjust the focus scale on a Belplasca?  I used
|ground glass and a target at 1 meter to check out the focus relative to
|the scale on the focus ring, and found that it is waaaay off.  I tried
|shifting the scale around the lens, but that doesn't work becuase the
|travel is still limited to the original setting.

|I tried to look this subject up in the photo-3D archive, but I couln't
|get that to work either.

|Help!

Jon - I found the following references in the archives...

(sample output from the search engine below for those of you who've not
tried it... sorry for the width of the display..)

I specified to look for "belp" AND "focus" close to one another, with case
insensitive matching and including partial word matches.

These are on http://calcite.rocky.edu/photo-3d

Thanks!
