I have a little piece of lint in my lens. It shows up when I take a picture. How do I get that piece of lint out of the lens. It is not on the lens but inside.
There are repair manuals on how to replace the lens. It would be the start of what you would need to do to disassemble the lens to get it out. Taking apart the lens module could introduce more into the lens, if it’s not done in a very clean environment. If you do go to repair it, you could make a repair manual for the steps you took to do it to helps others, too Sony Cyber-shot DSC-HX80 Lens Replacement
