Release detail
Release detail	Sony US announcement dated 7 February 2017 specifies March shipping in North America; exact first global sale day unconfirmed. Two independent full reviews read: Photography Blog Mark Goldstein on Alpha 7R II and OpticalLimits Klaus Schroiff, whose stabilisation assessment also uses Alpha 7R II. Preserve their conflicting raw distortion, vignetting and autofocus findings. Neither review material claim used as maker fact: Blog describes aluminium, OpticalLimits high-quality plastic. Blog sliding-focus-ring description is inconsistent with maker AF/MF switch. Geometric F numbers retained in main aperture fields; transmission explicitly qualified; no inferred predecessor link	Sony Canada announcement dated 3 February 2016 specifies March availability; Sony Japan later confirms 28 April 2016. Main date uses earliest maker-published month; exact first global sale day unconfirmed. Two independently authored full reviews read: Photography Blog Mark Goldstein and Amateur Photographer Richard Sibley, both using Alpha 7R II. Different stopped-down corner assessments and Blog lighting-dependent autofocus findings retained. AP page refreshed in 2023; its 135 mm APS-C equivalent and Blog linear-SSM description conflict with maker 127.5 mm and ring-drive SSM figures. No inferred predecessor link
