Kenko DG Tele Plus Auto Extension Tube Set
- Nikon Mount. The Kenko Auto Extension Tube Set DG contains three tubes of different length
- 12mm 20mm & 36mm
- which can be used individually or in any combination to obtain the desired magnification. Actual magnification effect changes with each specific lens. This DG Extension tube set has upgraded Gate-Array IC circuitry to work better with digital SLRs & some of the digital SLR lenses like the Nikon DX e. g. 17-55mm 10. 5mm digital-only lenses. 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 & in your pictures. They are exceptionally useful for macro photography enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. The extension tubes have no optics. They are mounted in between the camera body & lens to create more distance between the lens & film plane. By moving the lens father away from the film or CCD sensor in the camera the lens is forced to focus much closer than normal. The greater the length of the extension tube the closer the lens can focus. When using the cameras TTL metering system no exposure compensation will be required exposure compensation is required for handheld meters.
