High ISO test for Sony ZV E1 with Zeiss 35mm f2.8 shot at f2.8 with variable ISO upto 409600 with ambient light only.
Shot deep within the Welsh caves at King Arthurs Labyrinth. Hand held with no additional light and onboard mic only. Active stabilisation on, however in hindsight I'd have kept this off as it doesn't seam to work nearly as well in low light as it does in day light. Always in auto focus which was impressive for the most part considering how dark it was an older f2.8 Zeiss lens. Autofocus was slow to focus close up at times.
