Fuji X-T3 / X-T4 sticky topic In: Cameras Posted October 5, 2019 20 minutes ago, andrew_dotdot said: Zooming = uneven exposure. Is this a thing with the X-T3? --> So, I'm filming with my Fuji 18-55mm f2.8-4.0 lens, with the aperture locked at 4.0, ISO locked down, shutter speed 1/50th... What I expect: Since f4 should be available through the whole zoom range, I'd expect the exposure to stay the same through the whole zoom. What I see: Zooming in, it slowly gets darker, then snaps back to lighter three times on the way in. And vice-versa on the way out. Anybody know a way to avoid this or a workaround? If you search this forum, this questions has been answered a few times. The abrupt exposure shifts are due to aperture changes designed to facilitate movement of lens elements during zooming.
