The Kenko Auto Extension Tube Set DG contains three tubes of different length – 12mm, 20mm, and 36mm – which can be used individually or in any combination to obtain the desired magnification. Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens farther away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The Kenko Auto Extension Tube Set DG is compatible with Nikon DSLR cameras and F-mount lenses and is optimized to work with Autofocus lenses.
KENKO TELEPLUS PRO 300 2.0x DGX is a tele converter designed to make images more impressive by turning your master lens into a tele lens and capturing the object more close. By installing it between the lens and the camera body, KENKO TELEPLUS HD DGX 2.0x increases the effective focal length of your lens by 2.0x.
