A leaf or between-the-lens shutter is typically situated within the lens itself. This type of shutter consists of a series of overlapping metal blades that can open and close to control the amount of light that reaches the camera sensor. By being positioned in the lens, the leaf shutter allows for a more compact design and generally offers faster shutter speeds compared to focal plane shutters, as it can be synchronized with flash at higher speeds. This design is particularly favorable in medium format cameras and older rangefinder systems.

The other options do not accurately represent where a leaf shutter is found. The camera body usually contains a focal plane shutter, while the sensor is responsible for collecting light rather than controlling it. The viewfinder serves as a means for composing images but does not play a role in light modulation through shutter mechanisms. Understanding the specific location of a leaf shutter helps in comprehending its functionality and practical applications in photography.
