This one has been in my back pocket for a while and it is still worth sharing -- StudioBinder put out a video earlier this year called Everyone Gets This Wrong About Cameras, and the title is not clickbait.
The premise is simple and a little uncomfortable: most filmmakers know their camera's brand. Far fewer understand what is actually capturing the image inside it.
The video breaks down camera sensors from the ground up -- what a sensor actually is, the difference between CCD and CMOS technology, how sensor size affects the image, and what sensor qualities actually determine what you are seeing on screen. It is the kind of foundational knowledge that gets assumed rather than taught, which means a lot of working cinematographers are making camera choices based on brand reputation and spec sheets without fully understanding the underlying technology driving the image.
Sensor size in particular is one of those topics where misconceptions run deep. The relationship between sensor size, depth of field, light gathering, and the way a lens behaves on a given body shapes everything about how an image looks -- and it is not always intuitive.
What is the sensor-related misconception you encounter most often on set or in conversations about camera choice?
