I had an XA bought new in 1980. It's a fine camera but I only had it until 84 so I don't know the long term. I recently bought 4 XA's but none of of them really work. The RF faded so it's very difficult to see now. The meter needles on 2 of them don't work (although the cameras still expose film correctly because Oly built 2 metering system into the XA. One for exposure and one for just display). Out of the 2 working the one that has good metering doesn't look too good and has very faded RF. The other looks very nice and the RF is good but the indicating meter is off by 2 stop but the exposing meter is OK.
So I like the XA I must say finding a truly fully functioning one is difficult.
