Manfrotto 425B overview

  • 1Description

The Manfrotto 425B Mega Boom is the largest boom in the Manfrotto line. Movements -- including pan, tilt and rotation, as well as the telescopic extension of the boom arm -- are controlled by smooth-operating geared crank handles. This two section Mega Boom has a 12' (3.6 m) maximum extension. It has dual receptors -- Junior (1-1/8") and Baby (5/8").

This item replaces old catalog #3098. It is a boom only with empty counterweight bag. See the Accessories Tab for suggested Wind-Up Stands to complete your order.

A geared tilt system allows precise settings of +30 to -40°.
To assure maximum safety the Mega Boom comes complete with a specially designed counterbalancing sand bag that can be filled with sand or shot to hold up to 77 lbs.

    Manfrotto 425B reviews

    425B Mega Boom - 12' (3.6m) is rated 4.7 out of 5 by 7.
    Rated 4 out of 5 by from Heavy but worth it The Manfrotto 425B Mega Boom is not a light piece of kit. Combine it with a decent stand and that's quite a bit of weight to drag around the studio! But the flexibility is absolutely worth it!! I use it to hold high lights (such as hair lights and beauty dishes). It can hold an Octo no problems (I've not tried at full extension though), and it is fantastic for mounting a camera and shooting high perspectives and from above. It's not completely perfect though - there's a little bit of travel in the various gearings, so it can take some tweaking to get it into just the right spot. At full extension it is also quite bouncy, but I suspect that's unavoidable given the length. Overall, highly recommended!

    Rated 5 out of 5 by from Bigger is sometimes better...... Suspending a profoto head with a 3x4 soft box over a pool for an underwater shoot... I wanted to make sure that nothing electrical fell into the water - good underwater models are hard to find. I already owned a Manfrotto Super Boom - the Mega Boom was definitely a move up. Solid Secure Safe and no one electrocuted...

    Rated 5 out of 5 by from Expensive but solid, does the job. I have a Mola Setti beauty dish with Dynalite flash head mounted on this boom. Though expensive, it does the job. Wish I had bought one a long time ago. I have the rig mounted on a Manfrotto 087NWSH Short Wind Up Stand, which is also expensive for a light stand, and a monster, but this combination allows me to fine tune the light position and not worry about dropping a heavy piece of grip on a model. I also use it with a large Chimera softbox for still life work.

    Rated 4 out of 5 by from Great studio arm. I had been using a C-stand with a large arm for back lights. That was fine for smaller rooms but was not strong or safe enough for larger backlights such as 4' soft boxes. Not only does this easily handle the problem but it has 3 crank handles to adjust the light on each axis easily and precisely. I would give it 5 stars except that it is expensive, bulky to transport and one of the cranks is far from the other 2. I recommend a heavy duty crank up stand for this like the Kupo KS401212.

    Rated 5 out of 5 by from MEGA BOOM! Seriously amazing! we use our boom day in and day out, we had a dinky one before and this is the real deal.
    Date published: 2014-09-03
    Rated 5 out of 5 by from Mega Boom This is one of the best booms I've every purchased. I was planning on buying yet another super-boom and after looking at the specs on the Mega Boom I decided to give it a try. It's worth the extra money!
    Date published: 2012-06-15
    Rated 5 out of 5 by from 10/10 would buy it again. This thing is amazing. Gotta have a straight down light source on a scene but no where to hang it? Use this guy. It weighs about 35 lbs but the cranks are super amazing to use to rotate and position your light just where you want it without much stress.
