Ricoh published two updated Pentax K-mount lens roadmaps – click for larger view (645 and Q roadmaps were not updated yet).
There is a new lens on the roadmap: the HD Pentax-D FA 70-200mm f/4. Here is the launch order:
1. HD Pentax-D FA★ 50mm f/1.4 SDM AW: Spring 2018
2. HD Pentax-DA★ 11-18mm f/2.8ED DC AW: Summer 2018
3. HD Pentax-D FA 70-200mm f/4: Spring 2019
4. HD Pentax-D FA★ 85mm f/1.4: 2019
then, in no particular order (with a “2019 or Later” tentative release date):
The new HD Pentax-D FA 70-200mm f/4 lens will probably be based on the current Tokina AT-X 70-200mm f/4 PRO FX VCM-S.
