Looks like there's dust on your sensor. Get a Giottos rocket blower and/or some wet sensor cleaning swabs. Clean it gently and you're good to go. It's nothing too difficult.

>>2760852
For gods sake don't use a blower on the sensor!
Get a soft rabbit fur brush, you can get it at most art stores, and gently clean the sensor.
Use the blower on the lens.

>don't use a blower on the sensor

Why is that?

>>2760757
I get the same issue, except no spots on f/4 lots of it on f/22. What do? I think it's dust in lens, but the lens looks clean

>>2761041
This.
Never had any issues by doing so.

>>2761052
take a properly exposed shot without the lens on. If the spot is still there obviously it's on the sensor.

>>2760757
You have four options
1. If available, use the camera's sensor clean function.
2. Use spot healing brush in PS with the mage magnified.
3. If you're brave, clean the sensor yourself with a sensor cleaning kit using a zero-residue solvent.
If you're prudent, send it back the mfr.

To avoid, getting dust on the lens
1. Never change lens with the camera on.
2. Always point the body down when lens is off.
3. Obviously avoid changing lens in dirty, dusty, windy environments.

>>2761069
the spot won't be there with the lens off because it will be too out of focus to be visible.
>>2761052
The only time you'll see dust on the lens is in the borkeh balls, and only if it's huge. What you describe is the expected behavior of dust on the sensor.

That guy probably thinks a rocket blower is canned air or something.

Rocket blower is fine to use on the sensor. don't use canned air.

As people already mentioned: This looks like your typical case of sensor dust. Get yourself a cleaning kit or bring it to a camera shop.

I did clean my sensor with special cloth, but sensor dust makes no sense, I've taken real good care of it. Plus when I look at the sensor it's absolutely clean

EVERYBODY LISTEN THE FUCK UP

Dust on your sensor happens. It always happens. You can't avoid it completely forever.

Lenspen make a thing called the SensorKlear but it's actually just a Lenspen MicroPro with a bent handle and an expensive magnifying glass so fuck it. Blow it with one of these

>>2761166

Then get a Lenspen MicroPro and GENTLY wipe your sensor clean.

GENTLY.

The front of the sensor is a thin layer of glass and if you break it your camera is fucked.

>>2761300

The picture is much to noisy to see anything on it...

Take your camera. Go into manual. Set a small aperture <= 16. Bring the exposure time to >= 2 sec without blowing out everything. Aim at a bright white surface (white computer monitor). Take a picture and move/shake the camera while capturing. Take multiple shots.

If you end up with spots which are all in the same location when cycling through the picture then there is definitely dirt on your camera. You can double check by shining a bright light (mobile phone flash) on your sensor and looking from different angles at it. Remember that the final image you see is flipped, when looking for the spots.

Also, ugh. You shouldn't ever touch you sensor with any type of cloth.

Use:

-a blower for non sticky dust. (air cleaning)
-a sensor brush, a gel stick, or sensor-film for sticky particles. (dry cleaning)
-sensor swabs and a liquid for smudges on the sensor. The type of liquid depends on the type of smudge e.g. it can be oil or water based. (wet cleaning)

Note every cleaning method comes at a risk. Air can blow even more dirt onto the sensor, the brush might scratch or loose hairs or be contaminated with oil from the skin, the gel stick can leave a residue, sensor film takes long time to dry, liquid can smudge the sensor and might not fully evaporate.

In addition before using any of the non-air based methods check whether it is safe to use it on your sensor as modern sensors come with delicate coatings.

Depending on your geographical location and severeness of contamination it might be cheaper to give the camera to a shop and let professionals clean it.

>>2761327

Micro lens pens are used for cleaning lenses of compact cameras or viewfinders. To remove oily residue the cap is filled with coal particles. That is why you are suppose to twist them in the cap before application. While this dust has no impact on the IQ of a lens the sensor is a much more delicate part of an camera and unlike on lenses even tiny particles on the sensor become visible on the final picture given a small aperture.

That is why I would never touch a sensor with it.

>-a sensor brush
sorry this is what I used, not a cloth
