Yes, Viewpoint is a must-have, and FilmPack is very useful. The Volume deformation correction in Viewpoint is essential with wide-angle images. And I don't think an equivalent automatic correction tool is available elsewhere.

Volume deformation correction in Viewpoint, user have to input, correct?

not auto?

It's as automatic as you want it to be. In my case, I've set it up to automatically apply 75% horizontal/vertical Volume deformation correction by default to every image. That's what it will do unless I override it.

Of course, it won't change telephoto images, but will correct wider angle images as needed: the wider the angle, the more the correction. No user input required.

i don't understand why

if the lens need this correction (automatically apply 75% horizontal/vertical Volume deformation correction)

Volume deformation is not a lens problem. It is a characteristic of all wide angle images, even with fully corrected lenses.

why it is not in lens profile?

Because it's not a lens problem. In the example I showed, the lens corrections had already been applied, but the people at the edges of the scene had been stretched sideways.

This happens with all wide-angle images. As far as I'm aware, DxO Viewpoint is the only tool that provides automatic correction for this form of distortion.

See

Laowa Zero-d ultrawides have significantly less (almost non existent) volume deformation.

Volume deformation is a consequence of the wide angle. It's not a lens fault, and is different to lens distortion. Consequently, no lens is free of volume deformation.

Thus, the Laowa wide angle lenses have exactly the same wide angle volume deformation as other lenses.

The volume deformation is very apparent in these Ken Rockwell sample images:

He could have easily fixed it if he had been using DxO Viewpoint.
