Shot with my Sony A7iii, through a Mitakon Zhongyi Speedmaster 50mm f/0.95 III lens.
This was part of a boudoir test shoot.
I’m not sure of the aperture, the lens has no electronic communication with the camera, but it was probably somewhere around 1.0-1.2. ISO 500, 1/125 sec.
This image was lighted using a portable continuous red LED. It was shot using the b&w style in camera. The only thing that I did in post was raise the brightness .76 of a stop.
I think the only flaw with this otherwise solid shot is that she's a bit out of focus
