So I've heard that FF cameras have 1.3 stops more light but I can't wrap my brain around it for some reason. Because to me they're the ratios are the same just different sizes so wouldn't the lens and whatnot let in the same light? Does that mean that a medium format camera like a Hassleb let in even more light with the same FL and Ap?
Also if the lenses today are in F-stop i'm sure they're like 90% true to the T-stop so why would the sensor size play a role in the amount of light? I can kind of see if your using an EF lens on a APS-C vs a EF-S lens on a APS-C being different....
