EOS 5D Mark III What the heck is this on my sensor?

[deebators]

This appeared suddenly, looking through my pictures these appeared on a move from one spot to the next, I've been researching spots on the sensor, but WTF are those? nothing I see online looks like that; has anyone seen sensor spots like these or know what they are? This photo is cropped, but these are indeed on the sensor and not on the lens, confirmed by using a different lens when I got home. They are also more visible at higher apertures, invisible at a 2.8... visible at a 10, and sharp looking like this at a 22.

Looks like water droplets or some other clear material. Did you change lenses in the rain?

[deebators]

nope! not only do they look odd, they appeared suddenly... if I only was shooting at 22 (which I rarely do) I'd assume they have been there and I never stopped down enough to see them... but about 15 minutes prior I took some photos at a 10 and I don't see those spots there... I put the camera back in my hard case, back into my backpack and biked to the top of the hill where I noticed these while zooming in to check my focus.

Do you see them if you remove the lens and look into the body at the sensor? What camera is it?

[deebators]

I can see them on the sensor, I tried to simply open the mirror and blow the censor with an air blower, I've ordered a sensor cleaning kit. It's a 5D Mark III.

What seriously bugs me is that I didn't take the lens off, had the camera in a case and a backpack and these suddenly appeared... something distressing about how that could happen just like that out of nowhere

[deebators]

whoops, what I meant to say is, I CAN'T see them on the sensor, not with the naked eye and a flashlight

Ok got it. I find it helps to shine light from the side a little.Hard to do in a mirror box i know.Use reading glasses too, 3 diopter should do nicely.Cheap ones work fine for this task.
Can you let us know how the cleaning kit goes?I've cleaned sensors several times but not with a kit.Curious how well they work

Can you see them if you use Live View and enlarge to maximum view?

I have a 7D mark II that did that, not as transparent as yours, but similar. In my case, it was camera lube, and where in the camera it came from, I don't know. A regular dry sensor swab wouldn't clean mine and I had to resort to the wet method using the fluid that came in the kit.

When I bought my kit, I also bought a sensor loupe just for the heck of it. It's not something I use a lot, just for curiosity mostly. Looking at the sensor is pretty cool with a high magnification 🙂

Sensor spots become more visible at smaller apertures; are you saying initially you didn't see them at f/10 but shortly after at f/10 you did see them?
