Quiz: Sony 135mm GM or Sigma 135mm ART?

How much difference is there really between the Sigma 135mm f/1.8 ART lens and the Sony 135mm f/1.8 G Master? If you haven’t already seen the full video and comparison, start there. Do you think that you can see the difference in the fine details? Do you think you can see it in the overall rendering, bokeh, or color? You might get a better idea by taking the quiz below, where I compare the two lenses, and also slip in shots from a few other Sigma, Sony, and Canon lenses.

What first drew me to this shot was that it appeared that the woman's fingernails matched the stool legs.

This was shot with the lens wide open, 1/800th sec at ISO 400.

So, is this a Sigma or a Sony shot, or something else entirely?
