Re: Samsung 45mm vs Rokinon 85mm?

Kaziklu, sorry, but the shot on the right obviously has more distortion. The distortion that Samsung corrects for is not the same kind of distortion that we are observing here.

They correct optical distortion, in particular radial: http://en.m.wikipedia.org/wiki/Distortion_(optics)

They do zero about perspective distortion (which is why the reason the rule exists), and nor should they: http://en.m.wikipedia.org/wiki/Perspective_distortion_(photography)

As a result, the central portion of the image is more exaggerated in the image on the right, solely because you have to stand closer to get the same kind of tight framing. If you stand where you would with the 60 (but using the 30) and crop to make the same framing, that would give you the same perspective distortion.
