XA4 has a 28mm lens may be more expensive than XA. but it is compact and does not need a case.
I second Noel on the Olympus XA4. You can't go wrong with any of the XA series cameras (except for the ugly duckling XA1): they are well built, easy to use, very small and highly pocketable cameras, yet they deliver wonderfully sharp pictures.
Of course, for an all-purpose camera, the XA is nicer with its 35mm lens, coupled rangefinder and aperture priority AE (and yes, speeds are displayed in the viewfinder). But if you want a wider lens, the XA4 is hard to beat. Zone focusing is not a problem with a 28mm lens and the program AE works very well. The 28mm lens is a gem. It's even better than the 35mm lens on the XA, and it focuses down to 0.3m.
Unfortunately, while there are tons of original XAs selling for cheap, the XA4 is quite a rare animal. Even worse, legions of Lomomaniacs and other Holgazoids are driving the prices up, because they consider it to be fashionable. Nevertheless, if you are not in a hurry, you should be able to find one for around $70.
