VALUABLE BRONICA INFO
Some time ago I was roaming around the web and stumbled upon a site with a number of
"pdf" files on Bronica Lenses (and one on Polaroid Backs).
I have copied the files for my own use, but since the files are not my own,
I will list the file titles along with the web address...
All files are from: http://buonaluce.com/
Technical documents:
How the Seiko #0 shutter works: http://www.buonaluce.com/Anatomy.pdf
Evolution of Zenzanon Lenses: http://www.buonaluce.com/S2PS.pdf
Polaroid backs: http://www.buonaluce.com/Polabacks.pdf
Focusing distance (new): http://www.buonaluce.com/ClosedFocus.pdf
The tiny screws used on Zenzanon lenses: http://www.buonaluce.com/JCIS.pdf
Repair Tips:
Dismount a Zenzanon S lens: http://www.buonaluce.com/Slens.pdf
Dismount a Zenzanon PS lens: http://www.buonaluce.com/PSlens.pdf
Save a Zensanon S lens: http://www.buonaluce.com/sloppy.pdf
Check Seiko #0 shutters (updated): http://www.buonaluce.com/Tester.pdf
Adjust shutter times (new): http://www.buonaluce.com/Righttimes.pdf
I'm confident that although you may not own the "exact" lens in any of the articles, you will gain
knowledge on the workings of them. I know the info is not all encompassing but, I expect there will
be a fair overlap on the mechanical design of the wide range of Zenzanon lenses.
Enjoy!
