Release detailSony Canada announcement dated 30 August 2016 gives September availability; Sony Japan specifies 24 September 2016. Main release retains September precision because exact first global day is not established. Two independent full reviews retained: Photography Blog credited Mark Goldstein on Alpha 7S and Sony Alpha Blog Marc Alhadeff on Alpha 7R II. Amateur Photographer Richard Sibley was also read but closely overlaps Photography Blog wording, so it is not counted as an independent second review. Reviews disagree on detected colour fringing and barrel material; maker does not specify barrel material here, so it is omittedSony Hong Kong specified 25 June 2015 availability, with pre-orders separately identified from 10–21 June; Sony Japan specified 26 June 2015. Earliest accessible exact maker sale date is retained. Photography Blog sharpness-test introduction mistakenly names the 28–70mm zoom; its displayed 90mm tests and exact-model review remain identified, and no numeric sharpness measurements are imported
