What would be causing a thick black diagonal line in front of my camera's sensor?

From what I see this is element from the shutter. And my humble advise is to send your camera to repair shop, give it in to the hands of professional, do not try to repair it.

What would be causing a thick black diagonal line in front of my camera's sensor?

The item obstructing the sensor is a shutter blade. Your shutter has failed and needs to be replaced. There's no hack or DYI solution for this problem. This is a hardware problem and not something ...

If a rolling shutter travels from top to bottom, why does this image seem to show skew in the other direction?

You are correct that the image is inverted as it is projected on the sensor and that the mechanical shutter reveals the bottom of the scene before the top of the scene. What you have missed is that ...

How is uniform exposure achieved when using a leaf shutter?

There are actually a variety of leaf shutter designs, so a single answer might not be entirely appropriate... but it seems apparent that you are talking about the in-lens aperture diaphragm type. ...

Why are the tops of people's bodies missing from this photo taken with a tablet from a moving car?

This is very likely the result of an automatic HDR mode. Because of the apparent high contrast of the scene, the camera app tried to blend multiple pictures of the scene with different exposures ...

Removing "banding" lines caused from using silent shutter

This "banding" is caused by the primary light source in the image varying in intensity over time, and by the (electronic) rolling shutter in the camera converting this variation over time ...

How is uniform exposure achieved when using a leaf shutter?

The best way of approaching this might be by thinking of the aperture. A stopped down aperture does not only project light on the centre of film plane. Instead, the entire film plane is exposed more ...

Why do I have to press the shutter button twice to take a photo with my Canon DSLR?

You have probably enabled mirror lockup. The purpose of mirror lockup is to allow the slight vibrations caused by the movement of the mirror to dissipate before the shutter is opened. This is mostly ...

I have been doing this stuff since the 1950’s, I have never actually seen damage to a camera due to the springs taking a set due to prolonged cocking. Not to say that can’t happen as I was taught not ...

Why does electronic first curtain shutter affect rendering of blurred backgrounds?

The reason for the phenomenon is that at wide apertures in good light necessitating a fast shutter speed, most of the exposure is coming from a very narrow traveling slit between the first and second ...

If a rolling shutter travels from top to bottom, why does this image seem to show skew in the other direction?

Yes, you are right, the effect is opposite from what we would expect from a shutter moving downwards. And this is because the shutter moved upwards, or, more specifically, it was the electronic ...

Do rotary shutters have uneven exposure?

No, because the farther from the center it is the greater the rotational velocity is. I.e. the shutter travel speed is proportional to the radius. If you continue your simulation, the bottom of the ...

Why does my camera have a delay before shooting?

Do you have "Exposure Delay Mode" set? It delays the shutter to allow vibrations to settle when on a tripod. Should be in the D4 (Shooting/Display) menu. See The Manual page 280.
