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.
