T-stop system meaning

The T-stop system measures the actual amount of light passing through the lens, rather than just the theoretical F-stop value.

The T-stop system, also known as transmission stop, is a method of measuring the actual amount of light passing through a lens, as opposed to the theoretical f-stop measurement. This system is commonly used in cinematography to ensure consistent lighting across different lenses.

How Does the T-stop System Work?

In the traditional f-stop system, the aperture of a lens is measured by a ratio (e.g., f/2.8), which is a theoretical measurement of the amount of light passing through the lens. However, due to variations in lens construction and materials, the actual amount of light transmitted can differ between lenses with the same f-stop value. The T-stop system accounts for these variations by measuring the actual light transmission of a lens.

Benefits of the T-stop System

One of the key benefits of the T-stop system is its ability to provide more accurate and consistent exposure settings when using multiple lenses. By using T-stops instead of f-stops, cinematographers can ensure that the exposure remains consistent even when changing lenses, which is crucial for maintaining the visual continuity of a film.

T-stop vs. F-stop

While the f-stop system is based on a theoretical calculation of light transmission, the T-stop system provides a more practical and accurate measurement by taking into account the actual amount of light passing through a lens. This makes the T-stop system a more reliable choice for professionals who require precise control over exposure settings.
