PixAero now but problem with the sensor?

[kai_bcn]

Hi,
changed my lens to a PixAero 3,77 and all seemed fine at first but I have the black lines when filming towards the sun.
Any ideas what causes this?
Thanks for your time

It’s prop shadow. You need an ND filter to stop that. The increased focus of the lens will exaggerate that. Pointing towards the sun of course messes with shutter speed and white balance. I never fly in daylight without at least an ND 4 filter. It helps with motion blur and prop shadows but will make lens flares from sun angles. I personally don’t mind those and they can be artistic

This is without props on the H, the motors are not even running.
Interesting enough if you check the white of the building you don't see these lines. They only show up in the white of the sky.

In the video you can see what happens when I change shutter speed ...
