Both macro lenses render at 1:2. The lenses include a “floating elements” design, said to deliver high optical performance across the entire focusing range, from 0.24 m to infinity as in the case of the 2/50 ZE lens. The Makro-Planar T* 2/50 and Makro-Planar T* 2/100 are currently available for F bayonet (ZF) and K bayonet (ZK) cameras. The Makro-Planar T* 2/50 is also available as a ZF.2 version. Both lens systems are optimized for analog and full-format digital SLR cameras.
The 50 ZE should be in stores this month, while the 100 ZE is expected in early 2010.
