Extension rings for macro photography
An extension ring is simply a hollow cylinder that slides between the camera and lens, moving the lens further away from the sensor. This extra distance allows the lens to focus more precisely, which in turn offers more magnification possibilities.
Unlike many macro accessories, extension rings do not add any extra optics and are therefore relatively inexpensive and simple. They can be used individually or together. Since extension rings attach to the bayonet of the lens, they can be used with different lenses. Unfortunately, this is not possible with products that are attached to the filter thread. This is a clear advantage of extension rings. These extension rings are available in the simple form without data transmission; they are particularly suitable for older lenses that have a manual aperture. For lenses that have an electronic aperture control, the so-called automatic extension rings are more suitable. With these, the aperture can be set in the camera.
