We need a tilt-shift lens function in Octane, its very important for archviz.

Cheers

True

do you mean tilting the camera around it's axis, like turning your head onto your shoulder ?
or do you mean the perspective is only horizontal, eg the vertical elements/walls are all parallel ?

Radiance

parallel vertical element
Like in archviz photography

you can do that with nuking your scene in scale and decrease DOF...
Ive seen alot of renders here and elsewhere where people has a bad understanding of DOF which results in this effect - as in unintended.

gk, this is bad use of a tilt shift, just like bad HDRI photography, over-done
What we want in Octane is not that kind of result
Its correcting verticals, not adding extreme DOF

The goal is to have a normal lens (50mm for example) with almost no barrel distorsion

ah barrel distortion calibration, ok.
I use this on footage that needs to be 3d tracked from time to time.
Should have called topic something along with "barrel distortion fix" or something, got my mind on a tangent and radiance it seems as well

I knew Tilt-Shift as what gk was talking about, it is pretty awesome to use on a real camera, and you can use it to make strange perspective shots, but it is most awesome for making large scale things look tiny...
