It's in people's heads…
As they say, a picture is worth a thousand words, and a thousand calculations, I thought direct reference images were the best answer.
The images you find below are the comparison of the framing of two pocket4k and pocket6k then the 4/3 sensor of the pocket4k (not micro 4/3 as you often read, because that is the attack) against the Super35 sensor of the pocket6k.
Placing the easel 3 meters from the photo window these images show that the difference of crop is not extreme, it is not a real problem as so many go to demonstrate with so many absurd calculations.
As you can see in these comparison shots with several fixed focals 24-28-35-50 in an interior is not so dramatic.
Also since there are so many features in the narrow places (and 3 meters are not many) I thought it was useful to create a simple scheme between the two rooms so you see how the crop system is less important when we are up close, because the angle difference is less compared to being further away from the subject, but if you are further apart, you can move to compensate for the shots, so it's a false problem.
