A lightweight, affordable solution that turns almost any lens into a macro lens without sacrificing optical quality.

Extension tubes are a perfect solution to allow ultra close focusing without sacrificing the optical properties of your lens. ProMaster Macro Automatic Extension Tubes are engineered for a precise fit and proper communication between your camera lens and body.

The ProMaster 8819 Automatic Extension Tube Set for L mount includes two tubes (12mm, 20mm, and 36mm)  that can be used individually or in combination to gain the right magnification for your particular need. Protective dust caps and a handy neoprene storage case are also included in this premium kit.

These tubes maintain full electronic communication between your camera and lens. Functions such as AF, metering, etc... are kep intact. 

Even if you already own a dedicated macro lens a set of extension tubes offer some alternative benefits. Because they work with almost any lens, extension tubes can provide a different working distance. They are also lighter and smaller than most macro lenses which is terrific when you need to save weight. Extension tubes can often be used in combination with a macro lens for even closer focusing!
