Manfrotto Mini Boom Arm Reviews

perfect for me

This arm is really useful for my home setup where I do livestreams and shoot videos. The threads on the end make it easy to mount mics or small lights. it comes with these nice rubber caps to screw over the ends when you're not using the threads. I have a stand that has a boom clamp thingy, so it works well.

I wouldn't try using this boom arm for strobes but I used it with a speedlight,, works well and it was my original intention to use it for speedlights,,, very inexpensive solution when you don't feel like using a c-stand with a grip arm,,, good for a normal portable lightstands and speedlights

Great Small boom arm

Great boom arm, it is only 43 inches but, is long enough for many uses in studio or on location. It is a lightweight boom arm designed to use with the newer smaller more compact strobe heads and it is very well made. You will need to have your own counter weight setup as this is a boom only. I own several other larger Manfrotto booms so, if you are using heavier strobe heads and need a lot of length then choose another boom.

Versatile and practical

Not to small, build quality is excellent and a reasonable price. There are so many uses for this mini boom. I wonder what took me so many years to finally buy a few of these. You do need to use these in conjunction with a light stand and clamp of some kind.

Just what I needed!

Needed a way to mount a shotgun microphone to an overhead rod, but couldn't figure out how to drop the mic down low enough to speak into. This Manfrotto boom arm was perfect! Has threads on both ends so you can mount one end to a clamp, the other to a microphone or camera, or whatever you need. Simple, well made, love it. Only thing that would make it better would be a telescoping function (like a shower rod) to adjust length, but for me this length was perfect.

Expensive pole, but a nice pole

Came in the mail with a slight bend, probably because of the packaging. Had been shipped in a long flat-pack, and likely had another box placed on top of it at some point. Maybe B&H should send in a more substantial container, but it hasn't affected the performance of the item. Just a minor annoyance.

Can this hold a 21" LED flapjack light (about 7-8lbs), say mounted as overhead/straight-down for table shooting? (via SuperClamp attached to table, then Avenger grip-head to angle this pole 45º, then LED light pointed down towards table) Also, same question, but for mounting a Sony A7iii camera/lens setup (about 1400gram or 3lbs setup) for overhead/straight-down shooting on table?(via SuperClamp attached to table, then Avenger grip-head to angle this pole 45º, then small ballhead, then camera/lens setup pointed down towards table)

How long is it?
Asked by: Colm
I believe is 21 3/4 . I use it for holding small lights or light shades when shooting macro photography in a studio.

Will this work atop a Manfrotto 5001 stand with the 124 clamp?
Asked by: Anonymous
The 5001B stand is way too small to securely support a boom arm, pivot clamp, and whatever you are going to put on the end of the arm. And the top section of tubing is too thin to accept the 124 pivot clamp.I would suggest you go with a stand like the 1052BAC or similar.

what size is the diameter of the pole. 35mm? etc.
Asked by: Anonymous
The correct answer as to the diameter of the Mini Boom is 19 mm or 3/4 . I purchased the Manfrotto Mini Boom Kit which included the arm, 2 clamps, and a 3 lb weight. I also purchased the 124 Pivoting Clamp which is improperly advertised for the 3085 Arm. The Manfrotto Clamp will fit any boom arm that is 19mm, 20mm, 25mm, and 28mm.
