Howdy. Worked on a shoot in the Grand Canyon for a bit with my GH3 and "kit lens". Body did great lens got a bit sandy. Everything works as it should internally but the focus ring now has less than desirable "action". Am I crazy for wanting to try and fix this myself? If not, anyone got a line on an exploded diagram of this lens? Thanks.
It is really risky to disassembly such complex lens, especially as it is plastic. If you want to do this, find someone who is really good at this.
