Handy Boom


from North Chelmsford, MA  -  Pro Photographer

I have 4 of them. That says it. You can use it as normal stand, or give it a flip and convert it to a boom.




from Glenville, New York  -  Photo Enthusiast

I own two of these and will be purchasing a third.They serve as my general use light stands for off camera flash. Usually have Nikon SB-700's attached via an adapter and used with either Lastolite umbrella's or the Photek Soflighters. Whether using as a regular light stand or as a boom they operate perfectly. They are very easy to switch from a standard vertical stand into a horizontal boom arm and all you need is some weight to counterbalance your chosen load. Manfrotto makes a great bag for this that allows you to add your own weight and comes with a built in hook to connect to the nicely provided hole in the boom arm. Highly recommend this gear.


great boom for my DIY Beauty dish 20


from Signal Hill, ca  -  Photo Enthusiast

This boom works pretty good with my 20" diY combo with my sb900. it takes a little getting used to, over all I'm happy with the purchase. Must use counter weight. I needed a least 15lbs for my combo.

High Quality and Versatile - Buy it!


from Utica, NY  -  Photo Enthusiast

I use this primarily to position a hair light for portraits. But, it can serve as an ordinary light stand if needed. Its real versatility comes from its top section that easily converts to a sturdy boom. I use a small canvas bag containing anywhere from 2-1/2 to 15 pounds of bar-bell weights as a counterweight. The lower end of the boom has a convenient hole where you can use an S-hook to hold a counterweight bag. This top quality convertable boom stand lives up to the high quality I have come to expect from Bogen/Manfroto. The only negative (which is not really a negative for me) is it is quite tall when folded. If you use it as a regular light stand, it would be too tall for some specialized uses, like a background light holder, but it is not designed for that anyway.


Questions & Answers Powered by TurnTo®

Questions about this item:

JEFFREY B  Is this capable of attaching a 50" Wescott reflector? Thanks
MARK R  The Manfotto documentation states that it will handle 2KG at max extension and 20KG at minimum documentation. I would say that is fairly accurate.
Shopper  Does anyone know if this will fit a giant softbox (about29x59") and strobe? Total weight is between 6-7 lbs.
LLOYD L  yes it will, the boom will flex a bit if you are fully extending it and it will wobble around for a while after adjusted, bit it will hold so long as you sandbag it in a couple places. I don't recommend doing this if you have the money for something better but i use it every day
