Well, it's happened—after staunchly maintaining for years that it would not reverse-engineer its super-high-quality Zx lenses to fit the electronic Canon EF lensmount, Germany's august Carl Zeiss AG has either changed its mind or else entered into a cooperative agreement with Canon—because its new line of premium manual focus lenses, called ZE, is for Canon's EF mount, to fit all EOS film and digital SLRs. The lenses will cover full-frame digital models, and are compatible with AF confirmation, EXIF information, and E-TTL flash metering.
The new lens line will begin with the Zeiss ZE 50mm ƒ/1.4 Planar T* (below) and Zeiss ZE 85mm ƒ/1.4 T* (above), due to ship in the fourth quarter of this year, and expand from there. Initial prices are €486.50 (exclusive of German VAT) for the 50mm and €839.50 for the 85mm.
I didn't think this would happen, but it's certainly great news for Canon fans, who have heretofore been reduced to using Zeiss lenses with adapters and hence much less convenience and functionality.
Also expected soon is a version of the renowned Zeiss 21mm ƒ/2.8 for ZF (Nikon bayonet), ZK (Pentax bayonet) and ZE (Canon bayonet). The Zeiss 21mm, first introduced for the now-defunct Contax 35mm film cameras, has long been known as one of the world's best camera lenses.
