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.
This Autofocus Extension Tube Set (12/20/36mm) for Nikon from KOOKA contains three tubes of different length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any combination to obtain the desired magnification.
What is Extension Tube?
Using an extension tube to turn an ordinary lens into a macro lens
Ordinary lenses can normally focus to infinity, but when you pair a lens and an extension tube, the maximum focusing distance becomes limited. The extension tube enables you to get in closer to a subject but also limits how far a subject can be from the lens.
