Free hand shots (forgot the tripod). Two things to my advantage: build-in image stabiliser (Canon) and breathing technique I learned once with riffle shooting.
Freehand panning shot early in the morning.
Canon EOS 7D Mark II with Canon 100-400mm USM IS zoom on 400mm; ISO 400 S 1/30 and F 8
The image stabiliser works.
Napier Silos. Freehand shot with Canon 100-400mm IS USM lens mounted on Canon 7D Mark 2. F 5.6, S 1/40 ISO 640. The image stabiliser is working!
