Sensor dust showing up with closed off aperture?

4 years 5 months ago #663930 by Farestad
Do you find that sensor dust shows up more in smaller apertures more than wide apertures?   I just noticed that for me, at smaller apertures like f16+, I see more dust spots.  

Is that what you have experienced?

Yes, a stopped down lens will reveal those dusties better.

Why so serious?

Here's the procedure to see how dirty your sensor is:

1) You need a brightly lit piece of paper, or perhaps the sky. A single color is easier to work with.
2) Stop the lens down as far as it will go. f/22 would be good.
3) Manual focus and blur the image as much as possible.
4) Take a shot.
5) Examine said image. Any spots will show up.

Step 2 is relevant to your question. Stopping down, as well as areas of (mostly) solid color, will reveal spots.
