They're really easy to make... I've got a 20 foot or so long one. All you need is jack (2.5mm stereo), some wire, and two little push button switches (or a single dual-stage one).

If you're interested, I can write out a simple how-to.

That would be awesome. Thank you.

It doesn't need to be a specialty item for photography. As long as the diameter, tip and ring numbers are correct for that camera, any commercially available extension cord will do.

Give me a few days here, I'll see if I can find the materials to construct a new one and do a photo-guide with construction...

The dimensions of the plug and receptacle on the extension cord have to match those of the receptacle on the camera. Some plugs' diameter will be 2.5mm or 3.5mm or 1/8". The tip and ring specifications refers to the number of conductors in the wire. If you look at the plug, it will have a metal tip, which is one conductor, as well as one or more metal rings, usually separated from the tip and each other with plastic insulating rings. Each of those, as well as the metallic "sleeve", is also a separate conductor. So a monaural audio cable is a TS, like those used to connect electronic musical instruments to amplifiers, consisting only two conductors. The "rings" are added for additional connectivity, so a TRS cable works for stereo headphones, and a TRRS cable works to connect an audio headset with a microphone to a smartphone (for example). So as long as the dimensions and conductivity of an audio extension cable are the same as those as for the wired shutter release cable, the extension cord will work.

Sorry guys, couldn't find stuff to make a new one... but I'll try my best to explain here, if you have any questions, feel free to ask.

To start you need a 2.5mm stereo jack (they're not as easy to find as 3.5mm jacks but can be had online with no problems). There will be three connections on it; ground, focus/exposure, and shutter. I can't remember which is which, but it's fairly easy to work out using a bit of wire. Then use a three strand wire (or four, and you only need to use three of them), and connect each strand to a different connection on the jack. The wire can pretty much be any length you like. On the other end you need to connect one push button between the ground and shutter wires, and the other between the ground and focus wires. There you have it. You can make the end look nice if you like, mine was just soldered directly to the buttons and wrapped in copious amounts of electrical tape...

Just buy a 2.5mm stereo extension cord. They come in 6,12 or 15 foot lengths. Plug it into the camera, plug you existing remote into the extension.
