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.

I know how to clean it properly. I find both of your snide replies unhelpful at best, and derisive at worst.

Do you ever change lenses outside (or even inside)? They get dust eventually.

Are you trying to claim that your camera(s) never, ever have dust on the sensors?

Or re you claiming that you clean your sensor each time before you take a shot at f/22?

Clone the dust out in post. The post you are referring to had a photo that had much post processing, so cloning out the dust would be a "deckchair on the Titanic".

I don't shoot at f22 ever, but do test every now and then and may have a handful of spots at worst and don't even bother cleaning.

That's what I currently do, but sometimes the dust can mess up an important detail in the photo.

I'm not sure what photo you think I was referring to?  I wasn't referring to a specific photo (I didn't post one).
