This Tube Extension Kit is designed to be used with the Stacking Tube System, in order to increase the overall length by an extra 75mm. This is useful for situations when long lenses are going to be used inside the Camera Housing. The Stacking Tube System itself comes included automatically with the Camera Housing.

The overall length of the Stacking Tube System + Tube Extension Kit is 190mm. To work out whether the Tube Extension Kit is required, measure the distance from the front of your lens to the furthest forward part of the camera (usually the front of the wireless transmitter fitted to the camera’s hotshoe). The Tube Extension Kit should be purchased along with the Camera Housing if this measurement is between 140mm to 215mm.
