Caruba Extension Tube Set Sony E-Series Chrome APS-C and FULL-FRAME (Version II)
The Caruba Extension Tube set for Sony consists of two 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 mount and are compatible with Sony E-mount APS-C lenses. Features like auto focus and TTL light metering continue to work as usual. However, it is recommended to focus manually, 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 thus increases the magnification factor of a lens.
