Just for reference here's a video example (below) of a different Telescoping Video Jib. Keep in mind, this is not the exact same jib in the video, but hopefully you get an idea of how these systems telescope into full length Video Cranes.
This new Telescoping Mini Jib includes a fluid panning base, which means you don't need to invest in a a strong fluid video head. The base can mount directly to the 3/8" stud of your favorite tripod, or can sit inside a 75mm bowl mount tripod (for easier leveling). For those who hate traveling with standard weights, just fill up the included sand bag once you get to your destination.
Here's a fun little video a few friends of mine came up with to showcase basic dynamic camera movements using one of those new Carbon Fiber Mini Cranes (a.k.a Micro Video Jibs). This version breaks down into two pieces to about 30" inches, but can telescope to a full 6.5' Feet long.
In this video you can see that the crane was not used at full extension. Unlike a fixed length crane, these telescoping versions are handy when the project doesn't require as much travel, or if you're in tight spaces. It also helps to use it at shorter lengths so you can work with less counterweights. You can find these Carbon Fiber Mini Video Jibs following the link via eBay (Click Here).
The next product i'll be working with is the new Aviator Travel Jib (seen above) which is a one piece (not two) design, and collapses to an amazing 24"! It can still be telescoped out to a full 6' Feet and comes with a fluid base installed. This not only saves you money from buying a strong video head, but it also means you don't need to pack a bulky video head for panning. You really have to see it in person to appreciate the convenience of traveling with this little jib. The Aviator also has bearings at each pivot point for smoother vertical operation. The one piece design allows you to setup very quickly and break down just as fast.
I liked everything about the Aviator, but at a $500+ dollar price tag (seen here), I feel it will really target those who specifically need the convenience of traveling with a high quality uber-compact crane. If your goal is to get smooth Jib footage, of course that can be achieved by many different and less expensive products. If you are looking for a mini crane that is easy to travel with, can be set up quickly, and folds down to just 24" inches this may be the only current option. I will publish a video using the Aviator pretty soon. The Aviator is available in Mag Alloy or a lightweight Carbon Fiber version. More about the Aviator Jib can be found via Amazon (click here)
