Yes, but also a very bad way of making claims about a very technical aspect of a lens. I don't disagree that real life photos are a very good way of getting a feel for how a lens renders an image, I'm just saying they're not a good basis for those sort of claims.

Specs mean nothing. Images mean everything. We don't frame specs and hang them up on our walls.

I am not going to get into a discussion on what merits someone should buy a lens. I was merely stating that it is wrong to make statements about very technical aspects based on very untechnical measurements. Whether or not these aspects matter to you is completely irrelevant.
