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.

When buying a lens, what do we do? Look at someone's pictures taken with a number of lenses and make a selection based on what we see?

Specs might guide you a bit (i.e. focal length), but it's ultimately the samples that make the sale.
