| Release detail | Sony Europe specified May 2021 availability; Japan specified 28 May, separate from 23 April pre-orders. Main date retains regional month precision. Photography Blog and Digital Camera World disagree on flare resistance; their separate shooting results are retained rather than treated as a maker specification | Sony Japan specified 13 March 2020 sale, separate from 3 March pre-orders. Photography Blog already described availability on 2 March, without an exact first-sale day for that market; main date retains March precision, with Japanese day qualified here.
