Release detailSony 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. No UK list price imported from review pricingSony Europe specified April 2021 availability; March 2021 launch in Photography Blog describes announcement. Both full reviews were independently authored: Mark Goldstein for Photography Blog and Rod Lawton for Digital Camera World. Their edge-sharpness assessments differ. Sony specifies two linear motors, correcting Photography Blog’s XD designation. No unconfirmed fluorine coating is imported
