Re: Questions regarding T-Stops
by Rick Wise on Jun 17, 2012 at 6:39:24 pm
in the Cinematography Forum
Since the lenses you are looking at have ONLY T-stops, you can be comfortable knowing that the f/stops are almost identical and therefore there is no significant difference between them. Angelo's post lays it all out very nicely.

Thanks a Rick. The lenses I am looking at are mostly the Zeiss CP2, which seem to only have T-Stops. So these are just more accurate, geometrically based measurements of light rather than the F-stops which might be a bit off. Thanks again

While f/stops are a simple ratio of the iris size to focal length, t/stops are calibrated "light transmission" stops. T/stops take into account the amount of light lost in lens design. In other words, a t/stop of t/2.8 will transmit the same amoun

Professional older lenses, especially older zooms, are marked in both T-stops and f/stops. We use f/stops to calculate depth of field, and T-stops to set the iris. Example: Your lens is an f/2.8, the widest it can go. Your meter tells you to expose a
