Toward a wide view

I'm enjoying this camera a lot but as good as the 50mm so-called standard lens is - and it is -  I started to find myself needing a wider view for such things as group shots or landscapes with more of a feel of depth.

Calling in the camera shop, I noticed they had Olympus's own 28mm wide angle lens in its F2.8 form for quite a good price as the aperture settings are toward the front on Olympus's own which is easier and are well marked. 
This will come in handy for when I'm away on vacation and optically the lens is very good indeed.
