A rare snow day on Vancouver Is.

I have a new camera and lense and I have been trying to see how to make it capture an image I see with one I closed to eliminate the two eye 3D effect. I find for closeup scenes( 3 dishes with seashells) and close up that I can find a focal length and f-stop( maybe F4-F5.6) .The background is a window with blinds closed and the outside light is low due to cloud cover. What I notice is the out of focus transition is very different. With my eye the focus area with details is round in shape. The camera sees a rectangle. As my eye image goes out of focus if I keep the center area focused I seem to be able to match the immediate area with the f-stops mentioned. However at those f-stops the blinds about 5 feet away are way more out of focus and lacking detail in the camera than compared to my eye. So it seems not possible to match the rate(?) of out of focus as the eye seems non-linear? Also if i have the light level low then the above f-stop seems good for the immediate out of focus area. At higher light levels the lense needs stopping down, I believe this is mimicing the pupil of the eye closing.
