Sony or Sigma

Shot wide open at ISO 100, 1/1600th second at Kerry Park in Seattle, with the Space Needle in the Background, obviously. ;-)

Sony, Sigma, or larger aperture?

Shot at f/1.8.

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?

What do you think? Sigma or Sony?

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?

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 at least three different lenses, including the Sony 135mm f/1.8 GM. Which one was this?

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?

This was shot at f/1.8.

Photographed with the aperture wide open,  1/1000 sec at ISO 400.
