The Zeiss Distagon T ZE 18mm f/3.5 is a heavy-duty, manual focus lens that is perfect for those with a serious itch for landscape or nature photography. The Zeiss Distagon T ZE comes equipped with an electronically controlled aperture for ease of use and a well damped fluted focus ring that makes working with this Zeiss lens an absolute pleasure. Yet what separates this manual focus lens from the pack is the truly exceptional build quality. There are no plastic parts—just a surprisingly light full-metal brass body supplemented by a chromium-plated brass front bayonet. There is even an all-metal petal shaped hood that locks on snugly and securely, so users can be sure that once they lock the lens to the camera, it's on for good. Compatibility with Canon cameras is never an issue either, as this Zeiss lens works with everything from the EOS 620 to the 5D Mark II. Overall, for those photographers searching for a well-built, ultra-sharp upgrade for their current Canon lens, look no further than the Zeiss Distagon T ZE.
