Release detailSony Hong Kong specified mid-June 2022 availability. Independent full reviews were authored by Photography Blog Mark Goldstein, testing ZV-E10, and Digital Camera World Matthew Richards, whose sample images identify Alpha 7R III. Their wide-open sharpness results differ. Sony specifies one ED plus one Super ED element, superseding Photography Blog’s two ED claim. This is a G lens, not the G Master designation used in parts of that review; its unconfirmed fluorine coating is omittedSony 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
