Unfortunately this camera has neither manual exposure, nor exposure lock - so yes, it will be automatically changing exposure all the time, as it sees fit. You can help limit this by:John LF said:Did anyone notice sudden changes in exposure with the Vision camera?
I get small flashes from time to time when the light changes, I'm assuming it's the ND filter coming on or off.
Anyone else found a solution for this?

1) set ISO to 100 (not AUTO)
2) set White Balance to Sunny (not AUTO)
3) set Exposure Metering to Average (empty circle icon, I believe) so it uses the entire picture to calculate exposure, not just some small, rapidly-changing point in the center.
I haven't recorded much of anything for a long time, except static test shots. Unfortunately 6 weeks of nearly-constant rain here east of Seattle. But I don't what you mean by "flashes". Previously haven't experienced anything like that, and the videos I shot were mostly at 1080p30. Some sudden exposure changes are to be expected on any moving auto-exposure camera, though - worse if you choose spot-metering and also allow ISO to change automatically.ValHeliRC said:jimre said:Unfortunately this camera has neither manual exposure, nor exposure lock - so yes, it will be automatically changing exposure all the time, as it sees fit.

It has sense Jimre. When I record at 720p/60fps I get no flashes. Have you recorded at 1080p/30fps with this settings with no flashes?
ValHeliRC said:I Got the same problem when recording video at 30fps. Just change the recording settings at 60fps 720p or 1080i/60. I think in bright days the shutter speed increases the speed to compensate the amount of light resulting in those annoying flashes. Also the jello effect is perceptible at 30fps.
I ordered the filter holder and a kit of filters (ND 3 stops, CP) to solve this
