The rea lstrength of the venerated Olympus XA is the lens (35/f2.8), as much so it's cheerfully pocketable size and clever, functional design. Always keep in mind the challenges that Olympus engineers overcame in fitting a 6 element /5 group lens into a tiny body! Who else had done that?? Otherwise, I can think of the Rollei and Minox 'minis' with their quirky, sometimes irritating designs. It's a matter of personal preference. And availability. Many of these old classic 'minis' are now well used (perhaps over-used) and getting one that is reliable and that will serve you for any number of years is conjectural. "Seek and ye shall find."
