Think of it as a miniature version of a good old Oly Trip 35. You range focus on one of four focus distances, and get a wider range of shutter speeds than the Trip 35 offered.

And you have it with you all the time, it is so small.

If you get addicted, then move on and hunt out an XA, for (challenging) rangefinder focussing, and the ability to select your own choice of aperture.
