Triplus Auto Extension Tube Set for Pentax K cameras, consists of three extension tubes and you can either use these singularly or as a combination of two tubes or all three, the deeper the extension the closer you will get to the subject and the smaller the area that you will be photographing.

Ideal for small objects such as coins, flowers, jewellery and similar objects, being auto tubes the lens is still  meter coupled to the camera so the metering will compensate with the depth of the tube/s used.

Generally used with a standard 50mm lens.
