These lenses vs the Rokinin cine lenses? What would the difference be exactly?
Asked by: Benjamin
The Rokinon's have faster apertures The Meike lenses are smaller and have longer focus throws (which makes them more accurate to focus). It is also worth noting that Rokinon has several lines of cinema lenses from their DS series to their Xeen and Xeen CF. The Meike are closest to the Xeen CF in build quality. The Meike are compact sturdy lenses.

if the t stop is T2.1, is the f stop f1.8?

if the t stop is T2.1, is the f stop f1.8?
Asked by: Brenton
There isn't a constant F to T-stop conversion ratio since the T-stop is a measurement of the light being passed through the lens where as the F-stop is the size of the opening of the aperture. The F stop is only dependent on distance while the T stop is effected by all the things that change the amount of light passing through the lens to the sensor. But it is safe to assume that the F-stop is going to be a smaller number than the T-stop.
