The term full frame comes from the early days of dslrs when the only lenses available were 35mm film camera lenses.
35mm vs full frame camera.
Those beloved nifty fifty 50mm lenses are now 75mm lenses and so on.

If you mount the same lens to a camera with a full frame sensor vs one with a super 35 sensor the super 35 camera will give you an image that is 1 5x optically zoomed in.
The size of a 35mm frame in film photography is 36 mm 24 mm.
If you have a full frame camera then as i said above a 35mm is going to allow you to fit more in the frame than you can see with the naked eye.

The first dslrs had cropped sensors and would render different fields of view.
Full frame digital cameras use a sensor that s equivalent in size to 35mm film 36 x 24mm and is the largest consumer format you can buy without moving up into the specialized realm of medium.

That means it is great for situations where you want to include more of the environment in the frame or you need to be close to the action.
Full frame cameras have a larger 35mm sensor compared to crop sensor cameras.
