please!
cheers

Now that I have experienced long rendering times, i can say that Shift lens is a must.
The other way to create two point perspectives without shift lens, is placing the target point at the same height as the camera point. In addition you will need to increase the height of the rendering frame so that the top of the building will not be cropped.
But this force us to render an empty area of the image, to be cropped as posprocessing, but which requires a lot of ram.
Finnally this reduces the best possible resolution for your work.

Keep in mind that shifting a lens exposes vignetting (which is pretty abundant in M~R, use the search function for details...)

Kabe,
What do you call Vigneting?
I haven´t seen vigneting (as I know it) in any Maxwell image.
What I understand as vigneting is a total light blocking at the corners of the image, due in most cases to the use of thick frame filters, or to the use of lenses not calculated for certain cameras.
In such a case vigneting can be solved by scaling up the lens size!
If you call vigneting to the luminance level variation between the axis of the lens, and the image corners, I like it, and think it gives a great power to the corrected images using PC lens.
