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.

You’ll get 10 random questions out of a pool, so take it again to get a different look. For each question, click on the images to enlarge them. Remember, nobody cares if you pass this quiz; the point is to learn something along the way. Let me know what you think in the comment section below.

If you've seen the video, this photo should look pretty familiar. But is it like the Sigma or the Sony image in the video?

Shot at f/1.8.

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?

This guy was working security at the back door of the Showbox SoDo. I asked to take his picture, and he said it was fine, but he wouldn't look my direction. This was as close as I got to catching his face.

Sigma or Sony or other lens?

I photographed this model with three different lenses. Which ones was this?

A close up. This was shot wide open, and hand held, and if you look closely, you can see my reflection in the eye.

Sigma or Sony?
9.
This one was NOT shot wide open. This was shot at 1/200th sec. @ f/4, ISO 400, for not particular reason. Was it with the Sigma or the Sony?
