Century Optics XF-223B - 2x Extender for 2/3 Lens

In situations where it is difficult, dangerous or even impossible to move in close,

Century's 2x Tele-Extenders are the ideal solution. Easily mounting between your

camera and lens, they double your lens focal length, allowing you to fill the frame

with far-away action. Model XF-212B fits most 1/2" bayonet mount lenses (Panasonic and JVC),

XF-2325 is for Sony 1/2" bayonet and the XF-223B is for 2/3" bayonet mount lenses.

With a 2x Tele-Extender, subjects that were previously out of range will now fill the frame.


Get a shot across a stadium or over water. Attaching easily, the 2x instantly converts a 9-144mm

16:1 zoom lens into a 18-288mm super telephoto zoom. One caveat though, doubling the focal

length results in a two-stop reduction in the amount of light reaching the focal plane.

Characterized by their shallow depth-of-field, they also make it easy to isolate a subject from

foreground and background. For example, wildlife videographers find this helpful when shooting an

animal whose natural camouflage causes it to blend with its surroundings. Reduced depth-of-field

is also effective in shooting past visual barriers, such as chain-link fences.
