I have noticed an issue with fluorescent light. I vibration light appears in the image, speciality with slow motion. I tried to solve by changing speed shutter, but without resoults.
Use ECS Shutter Adjustment to fine adjust the shutter and eliminate the vibrations, at least I did it that way two days ago... had it on 1/48 and took it to 1/48.8 or so and it was gone.
