回答“Can I dissassemble the lens? I have dust insdide affecting photos.”No, it is not possible. To get inside the lens, you have to disassemble nearly everything. You can do it, I have disassembled my HX400V for another issue, but also cleaned the lenses with success. You can may have a look into my Teardown of the HX400V, which has very similar optical parts.
