Manfrotto 420NSB 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.

Great, just add weight

This was the perfect solution for booming a sit-down interview, but for peace of mind, add the few pounds of recommended weight to counter balance.

I love this thing. I use them for interviews and hang a mic over the subject. It's sturdy and strong, which is what I wanted in a boom pole stand. I got it directly at the store, but ordered it online. They were efficient and had it in stock.

Better than C-Stand

Love how compact this is. Much better alternative than using a heavy C-Stand. This has been my primary boom holder for all of my interviews. Found this halfway through filming my first documentary and its so much easier to setup and carry.

Sturdy, excellent product

Originally bought a less expensive boom stand/pole for back/hair lighting, thinking I would save some money. What I actually bought was a cheap piece of junk that broke within a week. THIS product, however.... this Manfrotto, as soon as I set it up... sturdy, got my backlighting exactly where it needed to be without any issues at all. Positioning the light EXACTLY not only where I want it, but HOW I want it (angle) was a breeze. STAYS there reliably. I set it and forget it. Sturdy, reliable product. That's it. HIGHLY recommend this boom stand.

Great Stand

I prefer this type of stand for traveling over a C stand and already use other standard Manfrotto stands that have worked great for my use case. I was unaware of this option until it was recommended to me and now I love it for being able to boom small soft boxes for Portrait Lighting. Add the 3lb or 10lb Manfrotto counterweight and you're good to go! It's a sturdy option.

Easy-to-use and durable, for a modest load

I can securely mount 2-3 Astera Helios tubes, even at full boom extension. Lightweight, well-designed and durable.

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.

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.
