Weird dots in photos EOS 2000D

[VideoMaster]

I had a Canon Rebel camera that kept producing weird dots in photos so I purchased an EOS 2000D. I am having the same exact issue with this camera. Recently went to an air show and took 659 pictures with 2 different lenses. Dots appear in all 659 pictures in the same position. Since I used 2 different lenses, there has to be an issue in the body of the camera. When I remove the lens, I do not see any debris on the mirror. I try to keep the camera at a constant temperature to avoid any condensation. Any ideas as how to correct this issue? I saw the same dots in another post and they were in the same position as well.

Please post an image so we can see your "dots" 🙂

"When I remove the lens, I do not see any debris on the mirror."

Debris on your mirror will not show on your images. It is flipped up and out of the way when you take the shot to allow light (image) to be captured by the cameras sensor.

It does seem odd that two cameras have the same issue, but I quit trying to rationalize things a long time ago... Still, my thought is sensor dust. But not knowing how often or what care you take when changing lenses, it's just a guess.

VideoMaster,

Two different cameras, two different lenses, same dots in the same place.

Sounds almost impossible to me.

The one common denominator though, might be the method you are using to transfer, or store, or reproduce your photos for web posting purposes.

1) Do the dots show up on your cameras' LCD screen when you hit Playback on your cameras?

2) What is the process you use to transfer the photos from your camera to your computer or tablet or smartphone?

3) Do you ever print those photos, and do the dots show up on your print?

OK, here we go do the simple stuff. A full reset of the Rebel T7. A brand new full size SD purchased from a known good retailer also a top brand exactly what the Rebel manual instructs you to use. Amazon and eBay are not good retailers. And never ever use a micro-SD with the plastic adapter. Never, never.

Now a more likely cause is the app you use to u/l to your computer and the app you use to create the images that have the "dots". If possible use a different computer. And if you don't have DPP4 get it from Canon, it's free. Use it to do all your photo transferring and editing.

You must think and eliminate the common actions.

Brilliant

1)- The dots are evident during playback

2) I use the EOS Utility 3 that came with the camera to transfer the photos to my computer

3) The dots do show up when printing. They are faint but prominent with blue backgrounds. Hard to see them on any other color. Mostly there with blue skies.I can erase them with another program but that is very time consuming and cannot be done in a batch mode.

Thanks for the images, VideoMaster!

To me, it does look like something on your sensor. My cameras get "stubborn" dust on their sensors every now and then that the built-in auto clean feature won't remove. I start with a Giotto Rocket blower, which works most of the time. If that fails, I use a sensor brush. Sensor brushes carry a light static charge created when the bristles rub together (lightly tapping it on your finger recharges it), they are also great for lenses. If it's really stubborn, I use a dry sensor swab but have used the liquid sensor cleaner that came with my sensor swabs. If you are squeamish about taking this on, by all means, take it to a pro.

**If you do give it a go on your own, follow the instructions that come with your cleaning gear**

Thank you for the advice. I'll give it a go and see what happens.

Hopefully, you have the most current manual for the T7. I have the T7i, which I haven't used for some time now, so I looked in the Manual For The T7 and it doesn't appear to have an auto clean setting and must be done manually, start on page 204.

I noted that you are using the EF 75-300. This series is not sealed well, if at all, and could be the source of the dust/debris on your sensor assembly. Zooming in/out sucks in air and pollutants and some of it makes its way into the sensor box. But that isn't the only thing that can introduce dust, just a possible contributor, so don't go trashing your lens 🙂
