diagonal lines caused by sensor

Hi,

I was looking through my images and noticed that all of them have two diagonal lines on the top right corner. I tested the camera with different lenses and the lines are consistent. So I am assuming that it is the sensor, but I am thinking it can't be dust, bc that would be a dot instead of lines. Can anyone advise me on what this could be and what I can do. My camera is a Canon 5 D Mark III. Thank you!

Krisztina

Hi, Here is the image, it is barely visible but it is there. There is a dust spec on the left side, but it is the top right corner that worries me.

Are you using a filter on the lens?

Have you cleaned or had the sensor cleaned recently? That would be the only thing I would think could be done without spending a lot.

No filters were used and I haven't cleaned the sensor yet - need to buy sensor cleaning kit

have a look inside the camera with the lens off & shutter open - anything on the sensor in the left-hand bottom corner to report?


some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", 1D MK II converted for IR, and now an M5

What are you using as a subject? and how is it lit? It looks to me as if it could be uneven illumination of the subject.

I see it in every scenario, but most visible in blue skies, first time I noticed it was actually on an outdoor shot with perfectly clear sky.

Looks like an AA or sensor coating that is marred.

I think so too, like maybe some lubricant or other substance is causing prismatic flare.

Ask your local camera shop if they have "Sensor Scope" in there, its a device that allows you to look to the sensor without getting dust into it. If its just oil spill or something else that can be cleaned off its easy fix. However I think its something wrong with filters on top of the sensor.

Looks like a smear on the sensor to me. Your first step should be to give the sensor a wet cleaning.

Here's a good introduction to sensor cleaning:

And here's a good tutorial:

I use the Copperhill kit for wet cleaning, as do lots of other POTNers.

Do you use always the same lens ?
