Sunset over Melbourne from Point Ormond.
Sony A7r3 with Sony 100-400mm f/4.5-5.6 GM. 16 averaged shots at 135mm, f/9, 1/640s, ISO 640.
A technically challenging shot - due to the wind, a single shot at less than 1/400s or so was impossible, even with a sturdy tripod, with or without IS. But shots taken at 1/640 were each individually sharp, and could then be stacked and averaged to produce the equivalent of a longer exposure at a lower ISO. 16 shots at 1/640, ISO 640 gave the equivalent of a single 1/40 exposure at ISO 40, without the camera shake issue.
