#1 is interesting because it appears you captured some flicker from the streetlights. Also an outstanding example of dragging the shutter on a pan shot!
Thanks again John. I'm really inspired by your work.
I'm guessing that's a radio pole or something on pit lane for one of the teams... or maybe in the paddock on a trailer. But it's only one pole. If you notice, there are 8 steps... so those are representative of the number of blades in the lens. 500mm L Series f/4 and a shutter speed of 1/15 sec. Here's the EXIF.
