As with all EF compatible lenses, the new ZE lenses from Carl Zeiss transfer all information exclusively via electronic contacts. This means that all exposure modes such as programmed auto exposure, shutter priority, aperture priority and manual setting are supported. The aperture setting is controlled from the camera body and the automatic focus confirmation remains available to an unlimited extent with these manual focus lenses. With digital SLRs, the lens data and all exposure data can also be accessed via the camera’s EXIF file. Even E-TTL flash metering is supported.
The first lenses to be available will be the Planar T* 1,4/50 ZE and the Planar T* 1,4/85 ZE in the last quarter of this year. Further focal lengths will be added to the line within the next few months.
