Carl Zeiss Makro-Planar 50mm F2 T* ZK + Pentax K-5
I read that Zeiss discontinued the ZK line in 2010...so once the current supply dries up...that will be it! I guess they stopped selling the ZK line due to a lack of sales. Hopefully if Pentax gets a full-frame DSLR...the market will be good enough for Zeiss to return to Pentax. I can only hope.
