Release detailSony Japan’s 24 August2011 announcement specifies December2011 for this exact lens. Main date retains maker month precision; exact global first day is not established. Full independently authored reviews: Photography Blog MarkGoldstein May2012 on NEX-5N, including sharpness and conclusion pages, and OpticalLimits KlausSchroiff November2019. OpticalLimits discloses sample decentring and reports the best corner; its raw vignetting/bokeh/value criticisms differ from Blog’s practical verdict. Sony Hong Kong’s NEX-5N press release contains erroneous blanket OSS/twoED claims for all three different lenses and a camera/accessory availability table that omits this lens; these are not used for this model. Maker exact numeric specifications and Japan exact-model optical design take precedence. No unpublished weather-resistance claimPhotography Blog’s contemporaneous 24 August 2011 US-price launch report specifies December availability; Imaging Resource’s later exact review corroborates end of 2011 release. Sony Japan delayed its local launch after Thai floods and finally specified 9 March 2012. Exact global first day unconfirmed. Sony Hong Kong added the black finish from September 2013; it is a colour configuration, not another generation. Two full independent reviews: Sony Alpha Lab Jay on NEX-5N, mostly corrected JPEG samples, and Sony Alpha Blog Marc Alhadeff on Alpha 6000. Their corner-sharpness judgments differ across bodies/tests. Unconfirmed ED glass/motor subtype in third-party descriptions omitted
