The Opteka 6.5mm f/3.5 Circular Fisheye Lens offers an incredibly exciting perspective and takes photography to a range that exceeds the ability of the human eye. Bend the typical view of your photographs and video to the extreme with the ability to capture a full 180 degree panoramic frame. That fishbowl angle, combined with the impressive 11.8-inch focusing distance, allows an incredible depth of field making the 6.5mm the perfect addition to your bag of tricks. 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.
While this lens is designed for APS-C sensors, full frame users can now use it without the hood. 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 and close images will appear proportionately large for a dramatic effect. This is a manual focus lens. You can only use the lens in "M" manual exposure mode or "A" aperture-priority 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. The special fisheye design allows maximum creative expression.
Opteka's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.
In order to assist with the common and annoying problem of flare and ghosting, Opteka's Fisheye lens has been coated with a special layer above the optics to reduce this harmful effect.
Additionally, a removable petal shaped lens hood is included reducing further the amount of light directly on the lens. This provides a valuable shelter from unwanted light rays helping you to capture ultra clear and vivid images.
