Re: DXO : t-stop is the effective way of measuring aperture.

A bit OT, but with all of the talk of T-stop, I wonder how the Oly 12-40 f2.8 lens is wide open at 12mm.  I just got it and it feels brighter than f2.8 whenever I shoot with it. Not sure why . But it has a lot of surfaces so I expect the T-stop to be lower than f2.8 considerably but it actually feels brighter than f2.8 for some reason.
