Zeiss has finally gotten around to releasing more lenses with a Canon EF mount. The Zeiss ZE line has been slow to surface to the public. The new Zeiss ZE T2 35mm should be available by mid November with a street price of under $1000.00 US.
The Zeiss manual focus lenses are well suited for cinema work. I recently tested the Zeiss ZE T1.4 50mm against the Canon L series T1.2 50mm and found the Zeiss ZE to have a touch more contrast than the Canon L.
