I like this photo because of the lines.
I was experimenting with a vintage Vivitar zoom manual focus lens at 200mm with a 2x teleconverter designed for a 35mm film camera attached to a Minolta MD to Sony E mount adapter. Tech info: 1/1000 sec. ISO 250. f/9.
If my math is correct, this is equivalent to 600mm at f/9 by the time it is processed by the camera's sensor.
