Solid for the money- read on for limitations/suggestions
on February 5, 2013
Pros: reasonable cost, comes with a sandbag and attachment carabiner, has a quick release for the strobe/modifier.
Cons: clamp is plastic (although good plastic), collapsed size is still 4', sandbag not very practical
The clamp has four different sized holes you can put a pole though. The smallest diameter hole it will accommodate is about 20mm and the largest is about 30mm. Use the largest hole that will still allow you to clamp it down on your light stand. This boom/clamp will not work with the cheap 7' light stands that are widely available, the top section of the stand is too small to fit the clamp at 16.5mm, and the combined weight of the boom system is far too great.
With the pole extended, you will need a counter balance weight in the 10-20lb range bringing the weight of the system (boom, clamp, strobe, modifier, counter balance weight) into the 20-30lb range. I have tested it successfully on the 9' and 12' Cowboy studio stands, as well as the Revelli 10' stand. You will need to sandbag your stand as it won't be stable with the boom.
Even though the clamp appears to be the same on both sides, it isn't. One side is for the light stand and one is for the boom. See my pictures to get the setup done correctly. I highly suggest marking the clamp to save yourself time down the road if you will not be leaving it setup permanently. I marked where the boom goes, as well the where the light stand pole goes for the diameters I will likely use.
The pole is in two sections, it collapses down to 4' and extends to about 6.5'. The base section is 30mm in diameter. The strobe end uses a standard 5/8" attachment point with the far end 1/4 threaded similar to most light stands. It also has a quick release which is handy. You may need to adjust the tension on the release levers using a small hex socket or needle nose pliers. On mine one was not tight enough and using it as is would have risked my equipment and the safety of those in the area.
The sandbag is like those seen advertised on amazon from various sellers for use in photography. Although the sandbag is okay, I won't be using with the boom because it's too hard to adjust. As you change modifiers and the length of the boom, you need to constantly be adjusting the counter balance. Trying to put in and take out sand (or other ballast material) with every adjustment just isn't practical. Instead, I'm using several weights from a barbell set, each one with cord attached and it's own small carabiner. This makes it easy to add or take away a couple pounds at a time. One could also use filled bottles of water or any other ballast that can be attached to the ring bolt. If you are using this in a more or less permanent configuration (same strobe, modifier, boom length) then the sandbag may work fine for you. I'll instead use the sandbag to hold down the light stand which is a requirement with this setup.
I hope this review was useful to you.
