Sensor anomaly in 6K

[Luke Neumann]

Has anyone ever seen this? I sent it over to my rep but wanted to see if any of you have noticed this before. I'm assuming it needs to go in for repairs.

Lower right corner. Took this frame in 6K FF and then went in to 6K HD and the green smudge was in the same spot, as if it's on the sensor. Not present in 5K.

Used different lenses as well and am getting the same results. Wasn't showing up in 6K a few hours ago.

That looks like it could be a hard optical artifact - could even be a crack in the OLPF or sensor.

Is it the same with different lenses on, or even without a lens on?

Try using an illuminated sensor loupe or bright LED light with magnifying glass to look at the OLPF/sensor. Remember lenses invert the image, so facing the camera you need to be looking top left.

At first I thought it looked magnetic.

Anything magnetic hanging off the right (dumb) side of the camera?

Yeah it's the same on different lenses and it moves as I window down from 6K to being gone in 5K. It's definitely behind the lens somewhere.

No, nothing like that. Very strange.

Camera warmed up to op temp???
just out of a cold car or production vehicle??? Or hot?

Nope, it has been inside and at room temp.

The odd thing about this defect is the orientation and the diagonal angle.
All of the sensor defects I have seen on various models of cameras have always been parallel to a side of the sensor.

But you have seen similar looking defects? Also, they just show up in the matter of an hour? Very strange!
