Bad aspect, clearly not 4:3
Let’s use 4:3
I am naturally exaggerating here. My point is that a categorical statement that 4:3 is better than 16:9 is nonsense. You should not blindly pick 16:9 just because it is there, in many cases the 16:9 format is simply the 4:3 image cropped. Case in point:
This is the exact same image, I just threw away the sky. In many cases, this is what happens when a 4:3 sensor provides a 16:9 frame. Perhaps you don’t want to save all those pixels of the sky, and you are not going to get a higher horizontal resolution anyway, so why not chose 16:9. I personally think it looks pretty good.
