Well - the title says it all - I've tried various solutions - switching to 35mm and moving back, leveling the camera, but none of these give me the same "view" that I get with the wide angle shot. Is there any other non-postwork solution? I've already messed with panoramic views, but couldn't get the same effect - I want the terrain to remain flat, the trees to remain upright, etc. Thanks for any tips!!

Here is what I set-up. 12mm is very wide angle and you need some space to get straight vertical lines. After the render I cropped the image.

Mazak - thanks again for your tips! While I couldn't get this particular image to straighten out and keep all other elements I wanted in the scene, your information will be very useful future projects.

cool render :)
I think you'll never get rid of that distortion,going that low on a real world camera would give the same effect..you could try using something like Pt-Lens to lessen the effect in post

12mm is heading towards ultrawide angle in 35mm photography terms - that's going to give severe distortion.  It can be mitigated a bit but you'll have a hard job removing it altogether

There's also the option of using a regular 35mm and doing a series of renders panning across the scene, then compositing them together in postwork. This wont work for animation of course, but is an option for stills.

You can minimize the "distortion" by keeping the camera level. And I think Mazak has the right idea (and a great scene).

I say "distortion", because technically the geometry is not at all distorted (not with a high quality real camera lens either) - it's just not what humans are used to seeing. For example, print the scene out, then wrap it around your head, a few inches away from your eyes. You'll have to turn your head to see it all, but what you can see in one view will have no "distortion".

I have a tutorial on Vue focal length effects.
