Opteka Fisheye Camera Lens for Nikon

What to Consider When Choosing a Fisheye Camera Lens

Whether you are standing under the Eiffel Tower or are at a local football game, a fisheye lens can help you capture a panoramic image of your surroundings. These lenses come with a variety of different focal lengths that you can choose, from 6.5 millimeters to 135 millimeters. They can also be used in combination with both digital and film cameras.

Here are some cameras that work with these lenses:

• Digital SLR: This is a type of digital camera that uses memory cards to store the photos and videos you capture with your fisheye lens. These cameras support interchangeable lenses and are equipped with both automatic and manual settings, providing you with the ability to change to whichever of the two modes you prefer.
• Mirrorless: This is a type of camera that comes without a series of mirrors inside, which causes the camera to have a relatively compact form. These devices use digital sensors and can accommodate interchangeable lenses.
• SLR: This is a type of still camera that is designed to use photographic film to record the pictures that you capture with your fisheye lens. These devices come mostly with manual settings and are outfitted with electronic viewfinders.
• Camcorder: This is a video camera that can capture video in both standard resolution and high-definition resolution. These camcorders typically come with a wide array of features and can save the videos you capture on many different types of media.

Different focus types include:

• Auto: This is a type of focus system that uses the camera sensor and a small motor within the camera to automatically focus on an object within the frame of the lens. This object can be identified either automatically or manually. Once the object has been pinpointed, the autofocus system will alter the focus settings before you snap the picture.
• Manual: This focus system requires you to change the focus settings of the lens by hand, which can typically be done via a thin ring that can be found toward the base or front of the lens.
• Auto/Manual: Some lenses are equipped with both autofocus and manual focus systems, allowing you to use whichever one you prefer as long as your camera supports both focus types.

The aperture of a fisheye lens refers to the amount of light that is let in by the shutter whenever it closes to take a picture. The maximum aperture lets in a sizable amount of light while the minimum aperture lets in a small amount of light. Maximum apertures are represented by an f-stop followed by a small number, such as f/1.2. A minimum aperture is listed with a higher number, typically that of f/18 or f/22. Some lenses provide you with the option of changing these settings manually while others include automatic aperture settings.
