About 3 Legged Thing X4a

The 3 Legged Thing X4a Jack Evolution 2 Magnesium Alloy Tripod is a stylish compact 79" tripod that features a removable leg, leg-spreading and a reversible center column that allows for low angle or macro shooting down to 5.1". The removable leg when topped with the included 4.0" column extension and the tripod's mounting plate, becomes a 57" monopod for gun-and-run scenarios.

The X4a Jack's legs are constructed from Stealth Magnesium Alloy which offers excellent lateral and torsional strength while reducing the weight to only 3.3 lb, while providing the stability of heavier tripods and supporting cameras up to 17.6 lb. It folds down to just 19.7" for easy packing and comes with a soft case and strap for storage and transport.

3 Legged Thing X4a Features

  • Structural Integrity: Constructed of Stealth Magnesium Alloy, the 26 mm (upper section diameter) legs offer excellent lateral and torsional strength
  • Friction Locks: Evo 2 Friction Locks with safety double break-point and easy-grip rubbers
  • Durable Finish: Retoned matte black anodizing and triple machined magnesium alloy parts for better durability and smoother finish
  • Inverted Column: With the column inverted and the legs fully extended, the user is able to lower the camera to the floor for macro photography. With an optional adapter, you can mount a laptop or iPad at the collar of the tripod to monitor your images while shooting tethered
  • Tri-mono Mode: Extending the center column with the legs retracted & spread to 55deg.is known as Tri-mono mode. This is a much better alternative to putting expensive gear like long lenses on the ground & keeps them at the ready while shooting with other camera/lens in situations like sports events
  • Extra Stability: Re-engineered leg mechanisms, for greater stability, smoother and easier use. You can completely remove the column and mount the head or even your camera directly to the tripod collar topped with the camera platform, providing the rigidity required for longer exposures
  • Compact Package: The design of the Jack is such that the tripod, when folded, will easily fit into most hand luggage. The D rings on the included bag allow it to be connected to another bag or cart for easy transport

Solid and very versatile


from NY, NY  -  Pro Photographer

My wife bought me this tripod a couple of months ago, and I have only just had an opportunity to try it out. It's the first time I've felt compelled to read the instructions - this tripod does an insane amount! I'm currently using an Acratech head, and this tripod folds over it beautifully. It's solid - four sections is probably more than I would usually want, but there's no flex or any twist in the legs when extended. I wouldn't use it at full height with a camera, unless just using it as a stabiliser (like a monopod), but it's awesome for using with strobes and I used it to hold up a scrim last week. The best thing about this is that it goes real low. I was shooting some macro last week, and inverted my camera to sit at ground level. I have a nova flex gooseneck with a flash, which can mount on the other end of the column (this thing has so many mounting points!) and the results were awesome.

Terrible legs for the price!!!


from Southeast U.S.  -  Pro Photographer

Bought these after hearing some good things and when they arrived I was incredibly dissapointed! The construction is absolutely terrible, very cheap and weak! They are incredibly unstable, there is no way one could get sharp long exposures, they are just not stable at all. The only good thing was they were tall and lightweight. I would 100% NOT trust any camera on them!!! For an extra $100 you can get way better Slik, Gitzo or Manfrotto legs (they just are not as tall).
