Manfrotto Convertible Boom Stand Reviews

Not bad, but not great

By Eddie

Considering the brand, I was expecting it to be a bit more sturdy. I can't say that it feels flimsy, but it as does have a noticeable amount of flex/wobble if you put even just 2-3lbs in the boom position (counterweights are a must). That said, at least all the knobs and such feel durable enough for you to crank down hard and tighten them w/o making you think you might strip something. One note, keep in mind that the height of the boom position is not 12', that is just the max height if you use the boom section vertically. It's fine for my needs, but might not work for others.

Great reach from this Boom stand. Holds the Nanlite Forza 300 with a Parabolic 120 Softbox. Easy to use. Sturdy AF.

question

Compared to the 420B, apart from lacking a sandbag, is this also a less robust stand? I notice the maximum load is lower for the 420SNB.
Asked by: Terence
The Manfrotto 420B, B&H # MA420B and the 420NSB are the same stand, with the latter not including the empty sandbag.

How well would this fair with a Profoto B10 Plus with an RFI 1X3 Strip box?
Asked by: Andre
At max extension this boom is rated for less than 2 lbs. It would not be suitable. The larger Avenger would be able to do it at a partial but not full extension. https://bhpho.to/3bH4yo9

Can this boom pole stand hold a DSLR and lens for a flat-lay filming as well? Thanks!
Asked by: Sarah
The Manfrotto 208 3/8" Head Mounting Plate with Lock Screws B&H # MA208 can be inserted at the end of the boom in place of the included stud. This plate can then accept a ball head such as the Manfrotto 496RC2 Compact Ball Head with 200PL-14 Quick Release Plate B&H # MA496RC2 to hold your DSLR. https://bhpho.to/2qzA4xA https://bhpho.to/2QuMfg0

I just received this stand, but I can't figure out how to lock or tighten the boom arm. Where is the thread lock on the boom arm hinge?
Asked by: Nader
When the boom arm is fully extended and the spring lock is pushed downward, the arm can be locking using the main ratchet handle to the left of the spring lock.

question

Can I attach a microphone for video purposes?
Asked by: Evan J.
The end of the stand will hold a standard Manfrotto stud - some come with 1/4-20 threads so you could attach a mic holder but you would need additional parts. The stand is sturdy enough to hold light heads so it could certainly handle a microphone.

question

Does this model include the ratchet lever to lock the boom arm? I ordered this model and it is missing this piece.
Asked by: Pedro R.
Yes it does have a lever about 2.5 inches long to tighten the boom arm however it does not ratchet.
