There is a difference between F-stops and T-stops. F stops indicate aperture size, thus giving you an indication of the defocus you can expect. T stops give you an indication of transmission, this is why cine lenses use these instead.
I also find extreme vignetting to be an issue with some lenses, but it's usually easier to forgive on fast glass
