One qualifying full exact review read: Bryan Carnathan, The Digital Picture, retail-sourced lens, April 2026. Sony Alpha Blog explicitly reuses original-version optical testing and Ken Rockwell redirects performance to original-version testing, so neither is counted as a second independent exact-model test; review summary omitted. Unverified fluorine coating and switch-gasket assertions in The Digital Picture omitted because absent from the read exact Sony specification/feature pages
