I even presented proof - a webpage associating the lenses with their designers (through patents); here it is again: http://douglasviewfinder.blogspot.ro/p/known-pentax-lens-designs-and-designers.html As for the assumption that Tokina lenses were launched before their Pentax counterparts so they're Tokina designs: - 100mm f/2.8 macro: Pentax in 2004, Tokina in 2006; designer MASAKAZU YAMAGATA - 12-24 f/4: Pentax in 2005, Tokina in 2004; Tokina design - 10-17mm fisheye: Pentax in 2005, Tokina in 2007; designer TAKAYUKI ITO+Jun Hirakawa - 16-50 f/2.8: Pentax in 2007, Tokina in 2007; designer MASAKAZU SAORI - 50-135 f/2.8: Pentax in 2007, Tokina in 2006; designer MASAKAZU SAORI - 35mm f/2.8 macro: Pentax in 2008, Tokina in 2007; designer YASUO KANAZASHI+KATO KOJI Launch dates for Pentax taken from DPReview. Launch dates for Tokina lenses taken from http://www.lensora.com/lenses.asp RE: Pentax lens roadmap 2017 - davidmanze - 03-01-2018 I did some checking as to the release dates of the Pentax vs Tokina and effectively the 16-50mm was released first by Pentax in 2007, the Tokina in 2009...... ......so I bow to your research! Dave's clichés RE: Pentax lens roadmap 2017 - Kunzite - 03-04-2018 15 elements... 8 in the focus group: https://www.dpreview.com/forums/post/60851218 RE: Pentax lens roadmap 2017 - davidmanze - 03-05-2018 As someone on the forum wrote: "It's good that Pentax are allowing Tokina to use their patent so that Canon and Nikon users can enjoy this creation." So let's all get one! Dave's clichés RE: Pentax lens roadmap 2017 - davidmanze - 03-05-2018 Actually the lens represent a significant jump in lens design from Pentax....with it's complex optical formula....I'm impressed! Pentax Forums will no doubt test the K mount version.........maybe Lenstip the Nikon or Canon version..... ......doubtless the K mount version will have excellent coatings, something that Lenstip consistently groans about with Tokina. It's certainly more complex than the Nikon AF-S 50mm F1.8 G that I'm waiting for.... ha ho ha ho.....with it's simple(ish) 7 elements in 6 groups (1 aspheric) At CP+ Pentax, seriously under their own named banner, were showing the new KI II with this new lens on it, they were also stating that they had another K series APSc body in design and the general flavour was optimistic. So they seem to have plans for the future!
