Should you always expose for t-stop?

[andytakeone]

If your light meter says to expose for f/4, does that mean you should set your aperture to whatever the equivalent of t/4 would be? (Lets say your t-stop is f/.5 behind your f-stop, thus you'd set your aperture to f/3.5 to get a "true" f/4 aperture.)

And also, is your camera's meter reading the light accurate to the t/stop value of your lens? Or does it mean you should always overexpose compared to your camera's meter considering nearly all lenses lose some light.

Thanks!

If you are not producing a video with several cameras/lenses in use then t stops are pointless. Just go with the declared f stop.

You should never use hardware without thoroughly testing that hardware. The results of your hardware tests contain the answers to your questions.

You need to study T-stops more, because the answer for some of your questions is there.

Where is the meter?
A hand meter is in your hand and reading the light directly.
A cameras meter is behind the lens and reading the light through the lens.
Therefore, a camera meter is already compensating for the transmission reduction of the lens.

What are you shooting that is critical to the half or quarter stop exposure difference?

If you are not metering with a GOOD handheld incident meter, then you likely are not metering accurately enough to make a difference.
