Zeiss
only makes FF 35mm lenses for PENTAX, their ZK series. With the possibly exception of their lenses developed OEM for Sony, they have totally ignored the APS-C era.
A company like Zeiss, it seems, lives at a pace where APS-C lives only as long as a wink, between 35mm film and full frame digital. If you look up their site, they reference documents from 19th century as proof of their innovative power
