not thrilled with the clamp


from Connecticut  -  Photography Student

I bought this as a boom for speed lights and modifiers for hair lights and future expansion to studio lights. Thought it would fit onto my current light stands (manfrotto 052B). Was surprised to learn the clamp needs a minimum of a 22mm pole to clamp to. That would have been nice to know before buying. The top section of my manfroto stands are 15mm. I ended up making a DIY adaptor from a 1/2 pipe and a rubber hose slipped over it, so consequently, I never take it off of that stand. I'll need to buy a sturdier stand with thicker tubes. But even with a stand with thicker tubes, adjusting the clamp is awkward with the plastic parks snapping into place with a pop as it's tightened. Not what I expected at all. Improve the clamp and it's a winner. With that clamp, I can't recommend it.

Does the job

in combination with a medium sized lightsource and a small strip-light softbox, this will make a great hairlight, kicker or accent light.

Questions about this item:

Shopper  Why Did You Choose This?
GARY J  Needed a boom arm for a hair light. Use my AB800 on this and it works well.
Shopper  I bought the Westcott boom arm and it must be mounted on a 1 inch tube. The specs says it mounts to a standard 5/8 inch but it cant be secured. This limits the usable height significantly. There are two plastic pieces that appear to be adapters for a 3/4 inch tube but they cant be used with an intermediate section of a light stand. Am i missing a part?
KAT G  I slid my light stand all the way through the hole on the black clamp. Then just used the black clamp to close tightly around the light stand that sticks thru the black clamp. Hope this helps.
