You know, you get to a point where either the person you talk to doesn't get it or just to stubborn to accept something.
It's stupid to compare one lens on crop to another on FF. I repeat STUPID!!!
The 100L vs 135L on crop. 135L looks better.
The 100L vs 135L on FF. 135L looks better.
Don't compare two lenses on two formats. Compare two lenses on the same format.
Once again, if 135L it looks this good on crop, it will look even better on FF.
