80MM Rodenstock Enlarger Lens with 6X17CM Curved Plane Rails

[Mustafa Umut Sarac]

We have an enlarger lens which fits to 6X6 Enlarger. Can I make a curved film plane rails 6X17 Camera or does it vignette at this size and 6X12 is better option ?

The widest 80mm Rodenstock enlarging lens I know of is designed for 6x7 images, not 6x17 or 6x12. Still an 80mm EL would cover 6x17 with enough bellows extension, but at that point it would be better to use a macro lens because you would be operating at high magnifications.

I am talking about curved plane camera where film to lens distance 80mm everywhere. I am asking does lens vignette at the corners or is 6X12 better option.

That is not how a normal optical system is supposed to work. A proper lens images a plane (or a scene at infinity) onto a plane perpendicular to the main axis (scheimpflug is outside the scope of this discussion).
Some cheap cameras had a (slightly) curved film because their lenses suffer from field curvature and thus can improve somewhat the imaging quality; nothing to do with enlarging lens.
Panoramic cameras with rotating lens have cylindrical film rails. But then the coverage (which you mention in your post #1) is a non-issue: because of the rotating slit the instantaneous angular field is small and well within the capability of the lens.

Is your question about the same idea as already discussed in:

Optimizing DIY Anamorphic Camera with Enlarger Lens Without Mechanical Shutter

I know stories about group f64. My workshop teacher has single 80mm rodenstock enlarger lens. We will build 6X24 or larger 120 spooled mid format film anamorphic cylinder camera. What is the biggest size format I can build for 120 film ? We will have lens at the top of the cylinder and...

If that is the case, what you have in mind is yet something else, and is not described in your original post of the present discussion; so it's difficult to provide a proper answer.

If on the other hand, the present discussion is about a lens sitting in front of the film, like in most cameras, there is no way a 80mm lens will cover 617 or 612.

You might answer your own question in an effective way by mounting the enlarger lens on the lid of a cardboard box, gluing some tracing paper on a window on the bottom of the box, and sliding the lid over the bottom of the box (focusing) while observing the image on the tracing paper under a dark cloth. Hands-on, concrete experiment. Much more instructive than an internet discussion.
