A T1 aperture allows for shooting in very low light, but usually, we can't afford it. With the new 50mm from Zhongyi, you can, and it looks pretty good too. Filmmakers love wider apertures because we can't control exposure times the way still photographers can. If you don't have enough light for a still photo, you put it on a tripod and extend exposure time, and if the subject isn't moving too much, voila, exposure. But filmmakers are usually stuck with 1/24 at minimum, and 1/60 or 1/120 (if shooting high speed) exposure times, and that isn't going anywhere anytime soon. So we need wide apertures to compensate. However, wide-aperture lenses are usually pricey, and they usually have optical drawbacks that make them less than ideal. I know at least one DP who regularly refuses to shoot anything more than 1 stop in from maximum, so if they rent a set of T1.4 lenses, they really shoot them at something like a T2 most of the time.
