That's not correct.
Studies have measured the cone of visual attention and found it to be about 55 degrees wide. On a 35mm full frame camera, a 43mm lens provides an angle of view of 55 degrees, so that focal length provides exactly the same angle of view that we humans have. Damn if that isn’t halfway between 35mm and 50mm. So the original argument is ended, the actual ‘normal’ lens on a 35mm SLR is neither 35mm nor 50mm, it’s halfway in between.
No, you are not correct.
It is really easy, take a 35 mm lens, mount it on your camera, mount the camera on a tripod, aim it at anything, then with both your eyes open, look at the same scene, then you will see for yourself.
