Buying a Contax T2 was a revelation that led to me selling my Nikon gear. Admittedly the T2 is heavier and bigger than the XA. Prices of all quality film compact cameras are especially low at present.
Agree the T4/5 are good lenses and cameras, but would also add the Ricoh GR1 or GR10 as worthy of consideration, excellent lens and light through use of magnesium I believe. The lenses are a little wider though.
