VERY weird - when i posted my answer half of it is cut. I see now. Renderosity is acting very strange these days. Extremely slow sometimes, extremely often with error messages. Now i even can't edit my comment. Therefore another try of the full thing.

Funny, i just looked a little closer to this last week. I always thought that the perspective changes too - but this was wrong. It is correct. I compared two images in Photoshop by simply overlaying them. The perspective is the same.

I don't really have an explanation to this - i just compared the focal lengthes of the camera(s). First thought is, that in fact the landscape position is basis for the image and therefore the image appears to be smaller on portrait ratios. But maybe i do a little more research on that and even look into some old computer graphics theory books to see how the perspective is calculated in relation to the ratio. The times of programming things like this are over a long time already. PS: I delete my first answer, looks too weird, cut like this.
