Can a lens alter dynamic range?

Hey guys,

I just recently got myself an exceptionally good copy of the 70-200L f4 IS. Best lens I have ever used.

I've noticed that my shots in high contrast scenes seem to grab more detail in the shadows and highlights than any of my other lenses.

Would that be possible or am I just imagining things?

I'll try to do some controlled tests between my current lenses and see if I am correct.

It can't alter dynamic range - it's just a piece of glass. It can obviously "grab more detail" which is why you're noticing it in the shadows and highlights. Lack of flare and better local contrast is also helping that.
