Canon Holder F3

[AgX]

This holder is basically a thingy that adds a lateral 1/4" thread base to a camera. Thus enabling to change the camera from horizontal to vertical orientation.

The same can be done with any ball-head or 3-way-head. Such holder though retains an exact 90° re-orientation.
And in contrast to the above heads it also retains the location of the optical axis. If apt for the camera.

The Holder F3 fits a Canon AE-1 though retains a height difference for the optical axis.
With Power Winder A mounted the height difference seems reduced to a few milimeters.

But the two 1/4" threads are positioned at different longitudinal distances from the film plane, thus re-orientation necessitates re-focusing in critical cases.

I am puzzled by this design.

They avoid excessive strain on the base of the camera that could distort it when using long heavy lenses.

Like the rolleifix for later rolleiflex cameras.

Thank you. That was a use I did not think of at all.

(For the quite similar holder F for the F-1, though without height differences, that use is not even hinted at in the semi-official german F-1 handbook.)
For the even less initiated: that holder kind of braces the front of the body, thus taking off bending from the base due to a long lens. But that brace at least partly is also needed to fix the camera when resting vertical even without long lens.


But still that does not explain the different thread hole distances.
And that was what puzzled me...

I have the one for the Canon F1 and don't use it very often. Leica used to make a similar cradle for their cameras.

Well, I thought that over and I think that both holders are intended to serve both purpose, re-orientation and stabilisation. The Holder F3 having higher bracing just to reach the camera body even with a winder attached, to protect both, stacked, screw connections from bending.

And that the mount distance difference (at both holders) is a design fault... as hard that is to believe.

Canon F-1 Holder

Benjiboy, any chance you could be coerced into posting an image of your Holder please? I also have an F-1n and would love to see one of these Holders ...

Thanks in advance!

Good to see is the different thread hole position that puzzled me.

From the photos it seems F and F2 are identical at the front side.

My F3 is very similar. Lateral foot is more off the body and there is no bracing at the back, allowing to open the backdoor.

It takes me and AgX to the correct eBay page Jim that is really odd.

That is strange. I’m using an old Macbook Air running both Safari and Chrome. When I click on the link, I end up at an eBay ad for a 1:18 model-version of a Ford Thunderbird (Nascar).
