An almost circular aperture produces a harmonious bokeh. It is remarkable for its solid and durable full-metal brass casing with a chromium-plate bayonet. The front element does not rotate while focusing. The focusing distance data are not transmitted to the  camera. There is a DOF scale on the lens, depending on aperture settings. It was elaborated in Germany, but is made in Cosina (www.cosina.co.jp), Japan, under quality control of the Carl Zeiss.

The Z-series Carl Zeiss Planar T* 1.4/50 lenses are produced for the following bayonet mounts:

• ZE - for the EF bayonet mount (Canon)
• ZF - for the F bayonet mount (Nikon or Fuji)
• ZF.2 - for the F bayonet mount with the processor (Nikon or Fuji)
• ZK - for the K bayonet mount (Pentax or Samsung). The production ceased in September, 2010
• ZS - for the m42 screw mount

The peculiarities of the Z-series lenses with various bayonets:

• ZE series - the aperture is controlled from the camera. The lens is not equipped with an aperture ring. All automatic modes  P, Tv, Av, M, as well as autofocus confirmation, function. The focal length and aperture values are transmitted to the camera. Some functions of the autofocus lenses (A-DEP) are not supported.
• ZFseries - lenses with manual focusing without the processor are not equipped with the AI aperture interface. Exposure adjustment and controls are possible with all the appropriate cameras. When using this series on cameras without the AI, the aperture is closed up to the  preselected value, but metering and automatic control are not possible.
• ZF.2series - both manual control with an aperture ring and camera control (therefor the aperture should be set at the maximum orange-colored value, and the camera will function in every automatic mode) are available. For cameras without electronic interface the aperture is set manually.
• ZK series - lenses with manual focusing corresponds to the КА standard. In addition, the lenses are equipped with electronic contacts. Besides, the aperture ring may be locked in automatic mode (green "А"). Thus, the control of exposure and various parameters (time, aperture, and program mode) is available with these cameras.
• ZSseries - lenses with manual focusing only are equipped with a pin for closing aperture. it has an M-A tumbler to choose between manual and automatic modes.
