Does anyone have any information on tronchet scope?

[Edith blazek]

There were a few threads on widescreen 16mm that had it individually brought up with links to defunct websites that supposedly had more information, but I want it for here, does anyone have any information on the 16mm anamorphic process known as tronchet scope, like what gear was involved? I know it was a system based on an anamorphic adapter placed in front of primes on a 16mm camera and that it was used on a few movies back in the day like Lucile Hadžihalilović's "La Bouche De Jean-Pierre" or "Jean Pierre's Mouth", Gaspar Noe's "Seul Contre Tous" or "I Stand Alone", and Carlos Reygadas's "Japòn". If anyone has any other information on this system please drop it here.

Sum total on Tronchet Scope?

 

“It fits the Zeiss G.O. series.”

 

“Il existe ‘officiellement’ un scope 16mm, c’est Thierry Tronchet qui l’a conçu et qui loue son système. Il s’agit d’un anamorphoseur 2X qui permet de rester dans une chaîne de post prod 100% argentique pour une projection en 35mm scope ! Il s’adapte à la série Zeiss G.O.”

“Thierry Tronchet, sorte d’inventeur fou qui avait mis au point un hypergonar sur lequel on pouvait placer des optiques sphériques, le tout produisant une véritable image 16 mm anamorphosée.”

Does anyone know if it really was the 35mm hypergonar lens that was used or if it was just referenced as a sort of shorthand for anamorphics?

I don't know for sure, but from what I've read Tronchet scope sounds like a simple anamorphic adapter like the Schneider ISCORAMA 56.

If you are looking for anamorphics both Hawk and Panavision have Super 16mm anamorphic options. I know people have been using the Laowa Nanomorphics, especially 27mm, on S16mm a bunch as well. They all have a squeeze factor of around 1.33-1.5.

I hope this was of some help.

Well yeah, but what's special about tronchet scope is that its 2x for 16mm film, the ones you mentioned are probably better for super 16 as it's a wider format.

Reviving the thread, can any French person here affirm or deny whether the use of the term hypergonar is a matter of that word being a catch all term for anamorphics there or if not which could mean that the core of the attachment is indeed the 35mm hypergonar lens?
