Tokina Teleconverter Camera Lens

Selecting a Tokina Teleconverter Lens for Your Camera

For outdoor shooting, a teleconverter can help you zoom into that distant landscape or get a close-up of a bee. A teleconverter fits between your lens and the camera's body to increase the focal length of your existing lens. A Tokina teleconverter is compatible with numerous brands that include Canon, Nikon, Pentax, Sony, and Minolta.

• Digital SLR (DSLR): These are digital cameras that come with an array of automatic and manual settings along with the ability to use interchangeable lenses. They use digital sensors and can record photos and video onto memory cards.
• Large format: This is a type of still camera that uses film. It comes in a large size of at least 4 inches by 5 inches. Some of the film used with these devices can measure as large as 8 inches by 10 inches.

A teleconverter is a tube with glass elements that is used in addition to your lens. It allows you to magnify your subject, yet it does not alter the minimum focal length. If you want to take extreme close-ups of flowers and insects, a Tokina 2x teleconverter doubles the magnification while you stay at the same distance.

• Auto: This is a type of focus system that will change the focus for you through the usage of a small motor and sensor. This system will kick in before you take any pictures, but keep in mind that a teleconverter may affect AF performance.
• Manual: This is a focus system that requires you to manually change the focus settings by hand. The focus ring that is used with this system is typically found around the lens base or middle section.
• Auto/manual: Certain lenses can accommodate both manual and autofocus modes, allowing you to switch between the two whenever you want. The switch that allows you to change focus modes is usually found along the side of the lens.

This term refers to how much light the shutter lets in when you are taking a picture, which can determine how much exposure the image has. Zoom lenses and teleconverters are factored into your decision of which f-stop to use. Maximum apertures let in a large amount of light and are typically displayed with smaller numbers, while minimum apertures let in a small amount of light and come with high numbers. This term usually comes with an f-stop followed by a number, such as f/18. The maximum ones available with these teleconverter lenses extend from f/1.2 to f/8.
