Release detailSony UK announced on 21 February 2023 and specified March 2023 availability. Photography Blog gives April 2023; the maker's earlier month is retained. UK launch price omitted because the actual Sony UK press page lists only a euro priceSony US announcement dated 11 July 2016 on PRNewswire gives shipping in July; Sony Japan specifies 29 July. Main release retains month precision because exact global first day is not established. Two independent full reviews read: Photography Blog Mark Goldstein and Amateur Photographer Andy Westlake, both using Alpha 7R II. Their wide-open sharpness and focus-speed disagreement retained; AP page refreshed in 2023 includes later GM context. Blog focus paragraph incorrectly says 71 mm filter; maker 72 mm used.
