Originally posted by JPT The 85 is at the same stage of development as the 50 was when it was shown under glass. The means it could be a year away. (...)
Yep, the first time the 50mm was shown under glass, it was at CP+2017 and it had a 3D-printed casing. People here might remember the strip of black tape that covered the end of the lens's denomination on the golden ring.
The same mock-up was shown in South Korea in April 2017 and in China in July. A few preliminary specifications were announced on 26 October and a working prototype was shown at PhotoPlus Expo (late October) and Salon de la Photo in Paris (mid-November). Additional specifications were announced just before CP+ 2018 and a prototype / pre-series lens was available for touch & try sessions during CP+. Initially scheduled for spring 2018 the launch then experienced a three-month delay because of production issues. Full-blown announcement took place on 29 June 2018 and the lens was available on 20 July 2018.
Same with K-1: mock-up under glass at CP+ 2015, working prototype in October 2015, announcement at CP+2016, available in April 2016.
Comparaison n'est pas raison, as we say in French (= comparisons do not provide all the answers, analogies are imperfect, or 'comparisons are odious' as one says), but I would bet that the 85mm f/1.4, except if delayed, should be available sometimes during spring 2020.
