Release detailSony Japan specified 25 November 2017 and Hong Kong end November; main date retains regional month precision. Photography Blog calls the hood round but lacked it in its sample; current maker specifications confirm petal shape. Reviews disagree on distortion and barrel material, so no unverified material claim is used. Amateur Photographer’s Alpha 9 AF-C failure is a historical sample observation; Sony separately acknowledged selected early serial-number units with focusing defectsSony Canada announcement dated 3 February 2016 specifies March availability; Sony Japan later confirms 28 April 2016. Main date retains earliest maker month; exact first global sale day unconfirmed. Two full independent reviews read: Photography Blog Mark Goldstein Alpha 7R II and Digital Camera World Matthew Richards, which does not state test camera. Differing35mm sharpness findings retained.
