Release detail
Release detail	Sony Europe specified February 2023 availability; Sony North America specified March, as did Photography Blog. Main date retains earliest maker regional month. Sony confirms F4 maximum aperture and two focus-hold buttons; Photography Blog’s F2.8 aperture-ring line and sibling 24–70 model reference are not imported	Sony UK original maker press specifies January 2014 availability; Sony Japan original announcement also gives January. Exact first global sale day unconfirmed. Two independent full reviews read: Photography Blog Mark Goldstein using Alpha 7 and Amateur Photographer Richard Sibley, whose original charts use Alpha 7R and refreshed page adds Alpha 7 III samples. Different focal-length preference, overall quality and blur assessments qualified by body/processing. Blog reverses wide/tele angles, corrected to maker84–34degrees. AP observed approx0.5m telephoto focus is not substituted for maker0.4m main minimum.
