A friend decided I could make use of her camera better than her (EOS2000D, apparently it's dated) but I'm not into photography myself. I find it a bit interesting though. Anyways, I decided to give it a try and I noticed some dust in pictures (pic related). I know there's software that removes this easily, I know how to get around it with whatever software, but from what I can gather, this dust seems to be inside the lens itself.
Course it's her camera, I ain't gonna fuck with it. But is this lens kit cleaning a complicated process? I would imagine that since she didn't use the thing for long (I'm talking years) some dust might have gotten in there somehow.

The dust is probably on the sensor. There is a sensor cleaning mode in the settings that will move the mirror out of the way. After that just blow fome compressed air into it

>>4434955
Isn't compressed air generally advised against when it comes to lenses and sensors?
I'm saying this because I'm seeing some dust through the lens itself, after removing it. I'm guessing whatever is on the sensor is much more noticeable than whatever sticks to the lens?

Air compressors are because they shoot out dust and humidity at high speeds
Compressed "air" cans as well (they contain petrochemicals not air)

Use a little rocket blower or specialized sensor swabs+sensor cleaning solution. Nothing else.

When you change the lens you're supposed to turn the camera upside down so dust doesn't settle on the sensor

it's fine

Dust on (stack of filters and stuff covering) the sensor. Easy to clean with a sensor swab and cleaning fluid if you know how to. If you do not, be sure to find out before attempting it. The sensor assembly is pretty tough but mechanics are not. Rubber blower is good in removing loose dust but what's stuck on sensor likely will not get blown away.
Compressed air or canned air is not suitable for cleaning optics and delicate mechanics.
Suggest taking it to local good camera shop if that exists and they will clean it for you in few minutes for a small fee and maybe sell you a blower, some sensor swabs and cleaning fluid.

>dust on sensor
Will be in every photo regardless of settings. Not exactly difficult to clean yourself with swabs and a blower, but if you're not confident after watching a youtube video pay a shop to do it.
>dust on rear/front lens element
Will become less apparent at wide apertures (f/2, f/4 etc.) and more visible as you stop down (f/8, f11+). An easy test is to take a photo of a single-coloured wall or piece of paper with the aperture super dooper closed (f/22, f/32). If it becomes more visible as you do this, it's somewhere on/in the lens. Rear element dust is more noticeable than front element dust.
>dust inside lens
Can't really clean it out without disassembly. Would not recommend to anyone for any lens that contains electronics, and only to those reasonably confident on a manual lens. Shops may offer to clean it out but many refuse since it's such a fucking difficult job for most lenses for such little reward.

If the camera was just sitting and doing nothing in a closed environment, I can't imagine the lens is clogged with dust inside. It's most likely sensor dust or rear/front element dust.

OP here, this is it, it practically disappears under f/8 or so.
I guess it's not such a huge deal. Using one of those air blowers for cameras I managed to at least get rid of a few spots anyways, somehow.

Glad to help. If it's any consolation, the 2000D probably has a shitty EFS 18-55mm that's worth $50. You could get a lens upgrade off ebay for $100 and you can easily find something without dust issues.

>>4434952 (OP)
This could be at the back of the lens as well.
