It's not chipped. After having compared it to some other very fast lenses I'm pretty sure though it isn't a T0.95 lens. There is light loss, or "efficiency loss", happening due to something when the lens is used wide open.

It would be technically impossible for the T stop to be equal to the F stop, wouldn't it? Even within only two digits of precision that would be exceptional, right?

All lenses will absorb some light, after all...

Of course, I should have worded myself more carefully and made clear that the loss of light is a bit more than expected. (I also think the f/0.95 thing is more of a marketing gimmick than the absolute f-value. Somehow it sounds sexier than f/1. This is more of an opinion though than the factual loss of light (or total exposure efficiency if you so like).

Jonas
