WebBelow, Granger explains the difference between f-stops and t-stops and compares a few lenses: Photographic cameras are normally measured in f (e.g., f/2.8, f/4) while cinema lenses are normally measured in t. Basically, the f-stop is the measurement of the opening of the lens; the t-stop is how much light makes it to the sensor. WebThe value of the t-stop is determined by taking the value of the f-stop and dividing it by the square root of the transmittance of the lens. Let’s use our two fictional lenses again: When used in conjunction with a lens that has a transmittance of 70%, the 50mm f/2.0 lens has a t-stop of 2.4 (2.0 minus 0.7 equals 2.39). http://frankdispensa.com/articles/filter.htm making a lightsaber at disneyland
