The XA is a very nice camera, but like a lot of cameras, it's been hyped to the point where expectations are raised to an unreasonable level.
I think the lens is very good. Not legendary but very good.
It has plenty of features: Backlight compensation, somewhat decent ISO range, self-timer, battery check and a rangefinder. However, do keep in mind that it's a very narrow base rangefinder coupled to a wide angle lens. For those of us who think the Cosina Voigtlander Bessa cameras have a narrow base rangefinder, try half of that or less (I should measure later when I get home). Still, it's nice to have one.
The body is a bit too smooth, and I can easily see a photographer dropping it. Same goes for the Minox 35 series. The Rollei 35 has enough dials, protrusions and body leather to make it more difficult (although not impossible) to drop.
On my camera, the meter needle is sluggish and inaccurate, although it seems to expose correctly.
