>>4272080So we know that regardless of focal length, the same f-stop lets in the same amount of light, but the t-stop adjusts that f-stop for how much light makes it through every piece of glass in the lens and finally hits the sensor.
Let's say your prime lens was an f/2.8, and a t/3.2 - it will be 1/3 stop darker than a perfect f/2.8 at every stop.
Your zoom lens is an f/2.8, but because of the significantly more complex design with the same grade/type of glass and coatings, it's a t/3.5, 2/3 stops darker than a perfect f/2.8. So it's 1/3 stop darker than your prime at every fstop.
if you shot both these lenses at f/4 1/60 iso 400, you're shooting one at t/4.5 and the other at t/5.
You let in less light with the darker lens. With less light, you have less signal, and therefore more noise, unless you lower the shutter speed 1/3 of a stop. That's a major annoyance for a video shooter, but a stills shooter wants more predictable DOF.
If you're thinking "hold on, why didnt i see was darker then?" its because whatever camera probably has a DRO/HDR mode on that brightened it for you and wrote that info to metadata so photoshop/capture one would honor it.
>RAFYep, DRO.
Don't listen to the nophoto tripfag. He's not very smart due to being 12, and he doesn't get to borrow his mom's camera often enough to test his "theories" so that just makes him more wrong more often.
