Release detailSony UK announced on 28 August 2024 with September 2024 availability; Sony Japan specifies 20 September 2024 for that market. UK first-sale precision remains the month. Photography Blog incorrectly gives F2.8–F22 in an iris-lock paragraph; maker F1.4–F16 is used.Sony Hong Kong specified late March 2017. Sony Japan brought the initially planned April launch forward to 24 March 2017. Main date retains month precision for regional release. Photography Blog Mark Goldstein tested an Alpha 7R II in 2017; Digital Camera World Matthew Richards published in 2022. Their wide-open edge sharpness judgments differ. Maker AF/MF switch specification supersedes an inconsistent sentence in Photography Blog saying there are no barrel switches
