Description:
Note:Camera and lens not included!
This high quality automatic macro Extension Tube Set is 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.
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 film plane. By moving the lens furthur 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.
It comes as a set (10mm+16mm).It contains 2pcs tubes in different length 10mm/16mm,and each tube can work alone.
It is with electronic contacts, which make it support automatic focusing,automatic exposure,etc.It enables you to use all shooting modes of the camera,exposure compensation is required.
