a6500 and 35mm 1.8

So I got a a6500 and the guy at the store threw in a 35mm 1.8 for free basically so i said why not even though I've heard people complain about it. I don't so much mind the sharpness but what's bothering me is the look of the separation between foreground and background. Whenever I have a person in focus in the foreground they look as though they are in front of a green screen, almost like the background doesn't look real. This being my only lens (I plan to add more of course) I was wondering if this is an issue with the lens or the camera itself. I haven't really seen it in other videos, hence the question.
 
Also if this is your first fast-aperture lens, the sharpness difference can look like that sometimes. Or maybe you're a super-experience user and you're seeing something my eyes don't usually see. Could you post an example?
 
I'll try to post something shortly so you can see what I mean. I only have fast-aperture primes lol but none of my other cameras exhibit this behaviour.

Yep, I shot some stuff with a 50mm outside, sunny day at f/2 or f/2.8 with an ND filter and when I looked at it later, "green screen" was the first thing I thought of.

In my case, I think it's because of the super shallow DOF, and the huge space difference between foreground and background with not much in between. But rather than bothering me, I thought "cool!".

That's the only time I've really noticed a "green screen" effect though.

Thats very normal with wide fast aperture lens once you get past 2.0 - our eyes are used to seeing blurred backgrounds on close ups - but wide shots are generally deep focus. If you want to get rid of it, its very simple - just close down the aperture to around 5.6 and that feeling should start to fade away. Blurred backgrounds on wide lenses create so much separation that it feels unnatural, especially outdoor shots. It tends to be better with indoor shots however.
 
Just be happy the guy tossed in a $450 lens for whatever. :) I really like that lens though. If I'm walking around, I'll bring usually bring 3 small primes-- like the Rok 12mm f/2, the Rok 21mm f/1.4 and the Sony 35mm f/1.8, or the Sony 50mm f/1.8. In terms of size, weight, price and IQ, my little a6300 system is hard to beat. Sure, I'd love an a7rII with both the Loxia and Batis lineup, but that's a LOT more cash for not nearly as significant a gain.
