Dual Dimension of Anamorphic Lenses.

It's kind of hard to describe it in words, but I can always recognize if a film is spherical or anamorphic by the feel of the medium (over the shouder) and close-ups shots.

Not sure what you mean by this - are you referring to the way in which a long lens is used to compress distance, while a wideangle lens may separate the subject from the background more - - 'increased spatiality'.
I am uncertain how that impacts the aesthetic sense of increased spatiality within the frame.
But these properties are not so much to do with the focal length of the lens as the distance away from the subject. The way I would think of it is that from the same camera position, a spherical and an anamorphic lens with the same focal length (in the vertical plane) will show the same image in the middle part of the frame - it's just that the anamorphic frame will extend out twice as wide.
As a result of that point, the anamorphic will show more "distortion" than the spherical, especially so with shorter focal lengths. That is, the distortion that comes from trying to fit a segment of a spherical view onto a flat rectangular plane. So I guess there is a different sense of space at the edges of the frame - but none at the centre.

i was always fascinated when i watched something shot anamorphic, widescreen in general. my approach to anamorphic is the following
we move most of the time horizontally.i think in general horizontal spatial consiousness is more advanced to vertical.one can estimate easier length and width than hight (todays kids are more 3d oriented ;-) ) so maybe thats the reason it makes picture more pleasing. think of it..
each day how many times do you look or inspect space (throught your eyes, your personal camera) vertically?, unless theres is something that distracts you, a voice, some noise or a very interesting subject.
i also agree to the fact that anamorphic gives wide aspect without distortion, which comes closer to eyes perception.

Max's previous thread implied that each anamorphic lens functioned in two focal lengths. I know that the squeeze and de-squeeze aspect of shot-to-projection corrects that dual dimension. Yet, it had fascinated me what two focal lengths in one image might do to DOF and bokeh. I am still trying to wrap my brain around the idea of horizontal DOF being different than vertical DOF in the same image. If this is the case, then anamorphic is significantly different aesthetically and therefore more than just a way to pack a wide image into a 4:3 frame.
