Caruba Extension Tube set Nikon Chroom (type II)

Caruba Extension Tube set Nikon Chrome (Type II)

The Caruba Extension Tube set for Nikon consists of three extension tubes that can be used separately, or combined. The extension tubes have no optical elements, which makes it possible to photograph subjects larger and from a closer distance, without changing the quality of the image. The extension tubes have a chrome base and are compatible with Nikon F lenses. Features such as auto focus and TTL light metering continue to work as usual. However, manual focusing is recommended, as focus is very tight.

Ideal for macro photography

Every lens has a minimum focusing distance. If you put an extension tube, or so called spacer ring, between the lens and the camera body, the minimum focusing distance becomes smaller. The greater the focal length of the extension tube, the closer you can get. This is perfect for macro photography or for creating special close-ups.

How does a spacer work?

A spacer ring increases the distance between the image sensor of the camera and the rear lens of the lens. This shortens the focusing distance of the lens, making it possible to focus closer on the subject. As a result, the subject is projected onto the sensor larger than it would be without a spacer ring. A spacer ring increases the magnification factor of a lens. This can be calculated using the following formula.

Maximum magnification with spacer ring = lens magnification factor + (mm spacer ring / focal length)
