Re: Alan, forget to ask you that..

First you need a piece of rubber to unscrew the large retaining ring in front, then 3 screws underneath.

Peeling inside and you will see 3 black colour screws with washers (see pic below). Loosen them a little (don't remove them completely) then you may adjust the focus. When done, tighten them again, and apply light duty threadlock on all screws. It is important to remember never overtighten them because the aluminium alloy is rather soft.
