the lens produces will vary slightly between cameras. The well-constructed and precision designed lens features a built in lens hood and a sturdy locking lens cap to protect the large front element from damage when it's stored or not being used to make photographs. The optical construction consists of ten elements in seven groups and is computer optimized to produce clear, crisp photographs, which is critical with a lens like this that is capable of extreme depth-of-field. When set at f/22 the result is a great range in depth-of-field that makes focusing less critical. The field of view with the APS-sized sensor is a full 180° producing the kind of super wide-angle view found only in much more expensive lenses.

to expand their creativity and capture incredible scenes from a truly unique perspective. This manual focus lens, when used with cameras with an APS-C image sensor, creates images with an expanded perspective , including images with a creatively deformed outlook and a sharp pan focus that extends throughout the entire frame. By offering a 180-degree angle of view , this fisheye lens can be used to create amazing image expressions that cannot be seen by the human eye, such as exaggerated perspective and distortion. The minimum shooting distance (just 12 inches) and large depth of field also provide amazing close-up shots. In addition, this lens incorporates the latest optical multi-coating techniques. The process of multi-coating assures virtually flare-free photographs even under adverse lighting conditions, resulting in crisp, high-contrast pictures. Key Feature...  (less)
