"...and a good sturdy tripod."
As I'm sure your aware, you'd have to change camera brands to get to a 50 ISO.
Certainly a scene that benefited from your skill.

No stack focus here. It's a single shot, 1/6s at f/22 (ISO 80). At
100% magnification the loss of resolution due to diffraction is
noticeable, but within reasonable limits for me. At 12mm I probably
could have used a wider aperture, but I wanted the longer shutter
speed. Really makes me wish for ISO setting lower than 80.
