Problem with lens extender?
I recently bought a new lens extender. I am fairly new to photography, and saw some photos that a friend had taken and decided that I wanted the lens extender that she used. It is an extension tube for Canon and is supposed to work on SLR and DSLRs. The tube fits my camera and the lenses fit onto the extender, but for some reason they don't seem to register on the camera. The aperture is always F00 even when a lens is attached. It was a cheap extension tube, and there was always the possibility that it wouldn't work, but I was wondering if anyone might have found a solution to this problem or could tell me what it is that I am doing wrong. Any help would be much appreciated.
This is the extender that I bought (unfortunately, most of the descriptions and things are in Korean, so anyone who can speak Korean and can help me would also be appreciated): http://english.gmarket.co.kr/challenge/neo_goods/g...

Your Canon lenses are electronically controlled by the camera body. If you look at the mount end of any Canon lens, you will see the gold-colored contacts, and if you look at the lens mount area of the camera body, you will see the pins that contact the lens. The camera body sends control signals to the lens through those pins, which adjust the aperture and operate the focus motor.
Now look at your tubes... which are distinctly missing those contacts. Without them, the camera has no idea what the lens is doing. It cannot tell you what aperture is in use, and there is no way to change the aperture from wide open. You should also set the lens switch to manual focus. There is nothing wrong with the camera or lens, the tube is preventing the communication the camera expects, and that is why you are seeing the F00 error. The camera is telling you that is has a lens attached, but it cannot talk to that lens.

Usually with cheaper extension tubes you will lose any lens to camera communications. This is because there is no electrical connection between the two. You can still use the tube but have to set your lens to manual focus. Hope this helps.
