“In the full format image, you can see a bunch of new lights near the top and bottom in the background. Take note of the green light on the top and the blue and yellow ones o then bottom. Notice the wall sconce that we see in the full format but not the Super 35. In fact, the inverse is happening in the foreground. You’re seeing less than what you’re getting in full format image than the Super 35 image.”
But still if you use the Super 35 at 6 feet and put on 30mm lense you will get exactly the same image in terms of the DOF, size of the bokeh rings and field of view. Especially if you don't forget to adjust the f-stop (multiply it by 1,5 please?) to compensate it for the sensor size too.
So what's this article about? Sensors are tools, you got that right, but everything else...
For those only starting to learn such things this article can be misleading. It is a waste of time for the rest.
