No matter how much I clean the sensor, it seems like whenever I try that small of an aperture there is dust visible all over the frame.

How do people deal with this? Cloning out the dust seems like a pretty long exercise.


Clean the sensor.


"No matter how much I clean the sensor..."

As you can see above, I clean it a lot. There is always going to be dust to some degree, even after cleaning.

Then I'll slightly rephrase the reply.  Learn how to clean your sensor properly.  I clean my sensor by shooting at f/22 until I have no dust spots.  It is possible to do.

Now, you want a challenge?  Try using your camera as a pinhole camera at something like f/177.  Cleaning your sensor to show no spots at this aperture is next to impossible.  Doing spot removal in post is the only way.
