Product Review

This is a manual focus lens. You can only use the lens in "M" manual exposure mode.

The Opteka 6.5mm f/3.5 Fisheye Lens is an excellent addition to any photographer's collection, giving users the ability to expand their creativity and capture incredible scenes from a truly unique perspective. This 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. On APS-C cameras the pictures will fill the entire frame or screen. On full frame cameras the lens will produce pictures with a semi-circular image.
