Rokinon 85mm f1.4 for pentax

Hello,

Rokinon 85mm f/1.4 Aspherical Lens for Pentax 85M-P B&H Photo

I was wondering if someone could confirm that this lens does have the "A" setting that allows your camera to select the aperture?
If so does this also mean that the camera will have exif data for the aperture used for a shot?
Would I also be correct in that the only thing manual is the focus and not the aperture setting?

So now for an example of the above questions into a scenario:
If I use this lens on a kx would it function like my other auto focus lens except for the fact I have to focus manually? As in when I look through the viewfinder would it be the max aperture 1.4 and then stops down when I actually take a picture if I had selected f4 for example in Av mode? Would the resulting shot have the same exif data if using an auto focus len.

Thanks

That is all correct. This lens is just like a Pentax A-series lens.

Correct again, except that the lens name will not be recorded in EXIF. It will just say A-series lens.
