user23721: I want the videos that I will shoot to feel natural and I don't know what I have to do.
The research I did in the internet says aperture of our eyes are around F/8 in bright conditions and around F/2 in the dark so what aperture should I use for realistic depth of field? .
As far as I learned. The filmmakers use the shutter speed of 1/48 for 24 FPS movies and these movies feel natural to my eyes so what shutter speed I should use? 
I have read any FPS can be received by the eye but for some reason. Every 60 FPS video I have ever watched in my life feels like plastic fruit and the internet says it's because we got used to the low FPS moviesthrought our lives do what FPS I should use?
Bit irrevelant but I did some research and it points out the classic 4:3 aspect ratio is actually closest to our vision so should I shoot in 4:3 aspect ratio? 
So what is the best way to get that "realistic and natural feeling" in the videos with a 30 FPS APS-C camera? 

user23732: You pretty much found it out yourself.
Use 24FPS, 1/48, Aperture around f4. (Depending on your sensor size)
You really can't get a 1:1 look as our eyes have a diffrent way to see the world than a camera. But those settings will feel natural when used right.
Also think about how you film, many people say shoulder rigs feel the most natural as you have a slight wobble.
For me shoulder rig + lens stabilizer has done the job.
Then, keep in mind how the scene looked so you can match the colors.
