Thanks Jørgen! I hope I'm not boring people to death with my project 

Here are some sketches of the support:

Kudos to the invention and also the artist who drew the sketches.
I love the bow tie on the photographer

I was about to ask the same question about the bow tie - hope you do have one of these, Erik?

[stenrasmussen]

I like the oily hair style. Have you been to the coiffeur Erik?

[Erik Lund]

With 220 degrees field of view the tie and loose hair will all to easily get into the frame - Hence the bow tie and grease   

[Bjørn Rørslett]

A pair of Pocket Wizards can be a substitute for the bow tie and the greased hair, but what about the dancing shoes?

[Hugh_3170]

Jakov, Kudos well earned I'd say.

Actually the sketches are helpful to an onlooker such as myself for they show quite nicely the challenges that a 220 degree field of view pose for the photographer and how they will be dealt with in this instance.

Nice work Erik and an excellent preparation. 

I just hope that the weather and light will be kind to all of  the Killin group and that in due course we get to see this rare lens performing to its fullest.

Kudos to the invention and also the artist who drew the sketches.

BTW There is a much easier fix than the 'safety ring'

It is to drill one or two holes and cut threads in the collar and through the ring.


I already have a screw like this in my Burzynski Ball Head adapter ring - Series 3-4 to Series 5 - so I don't loose the ring,,,

Erik, if you have a drilling machine, it should be easy to make it safer that way.

I don't think it is urban myth.  By Gitzo design, the bolt tighten the ring below the lower edge of the plate.  So, the more you tighten the bolt, the more the upper part of the ring will be open.  As a result, the ring is hold at the lower edge of the plate.

I replaced the central hub of my Gitzo Series 3 Systematic with the alternative hub made by Markins (TH-300).  So, the problem is gone forever.

Sorry for the deviation.  Let's go back to the original topic! 

[Erik Lund]

Yes this is true for the Series 3/4 - of course dependent on the depth of the plate this could be an issue,,, But this is not the case for a Series 5 where the bolt is located at the edge, not below, and when you tighten you can actually measure the collar getting smaller in diameter 0.2mm - closing at the top, not opening!

[Akira]

Oh, I see.  I will look closely when I have a chance to see a Series 5 one.  Thanks for the detailed explanation!

[Erik Lund]

No problem Thanks for the heads up Akira! For glass like this I will not take any chances,,,

[Akira]

You are welcome, Erik!
