Hard to tell from the image but If you do manage to loosen the lens retainer ring, you may find as you unscrew it it is still stuck behind the name ring.
On 20mm~ish wide-angles like that often the name ring & filter holder are one machined unit that needs to come off before the front lend group (or front element retainer ring) can be removed, especially if they are of the type where the filter thread rotates when focusing. Screws and/or fixing tape that allow the name ring and filter holder to come off are sometimes found underneath the focus grip waffle.
If that is the case with this lens you may also find that once the front group is exposed, you see thread-lock holding the front element retainer ring on an external thread rather than internal thread (i.e. the retainer ring may have a female thread and the cell body a male thread). This isn't always obvious from the outside. _________________ Mark
