Perspective in rendering differs from viewport / perspective matching

[OPKJoe]

Hello together,

I searched this forum and the internet but I couldn't find a suitable solution to my problem.

I want to recreate a rather difficult perspective since the original photo was shot with a 17 mm tilt-shift lens.
I did not manage to get the perspective done with the perspective match tool. I gave PFTrack a try, but either it isn't possible there too, or my knowledge isn't deep enough.

After about 3 hours I finally got the perspective really really close to the photo by hand.
But when I finally want to render, the rendered result looks completely different.
I assume that it is because of the lens distortion - may it be not visible in viewport?

Can you help me either in getting the image rendered in the same perspective as in the viewport or - even better - have any tips in matching a tilted and shifted perspective?
In the picture you can see the viewport, a rough rendering and the camera settings.

Thank you in advance.

I think for lens distortion which is adding the bendiness, there's no way to show it in the viewports, maybe set lens distortion to "none" to keep your lines straight in the render?

I think that too. Only tilt correction can be seen in viewport.
