Sony Japan later confirmed 7 December 2012 for that market; main release retains earlier US month, exact global first day unconfirmed. Sony Alpha Blog’s 2013 year is not first sale. Full independent reviews: Reviewed TJ Donegan, Alpha 6000 samples, and Sony Alpha Blog Marc Alhadeff on Alpha 6000. Their value and colour-fringing judgments differ. Maker 154 g/45 mm supersedes Blog155 g/55.5 mm; barrel material disagrees between reviews and is omitted. No borrowed sibling coatings or special-element counts |
