Kenko 10mm, 16mm DG EXTENSION TUBE SET for Sony Full Frame E-Mount
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 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.
CAUTION: For underwater use, a port extension ring will likely be required.
Install 10mm extension, or 16mm extension, or 10mm extension
plus 16mm extension together for 26mm extension.
The DG extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and sensor. By moving the lens further away from the 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.
