Product
extension tubes are designed to enable a lens, the greater the minimum distance set as a center of their normal game. Closer has the effect of magnifying your subject (which seems more in the viewfinder and on your photos). They are particularly useful for macro photography, enabling you to convert almost any target in macro lens at a fraction of cost while maintaining its original optical quality. The extension tubes have no optics. You must create between the camera and lens, the greater the distance between the lens and film plane mounted. By moving the lens father of the film or CCD camera, the lens is forced, much more than the normal point. Over the period of extension can not concentrate near the lens. The Kenko Auto Extension Tube Set contains three tubes of different length, 12 mm, 20 mm and 36 mm, which can be used individually or in combination to achieve the desired magnification. Tubes Kenko’s Auto Focus extension are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure.
