Angler FastBox Octagonal Softbox (20")

The FastBox Octagonal Softbox from Angler is a 20" octagonal softbox designed to set up and collapse in a fraction of the time it takes to set up a standard softbox. With a single motion, it expands to snap and lock into a classic octagonal shape, favored by fashion and portrait photographers for even lighting and round catchlights in your subject's eyes. The silver interior amplifies the output from an on-camera flash, and the inner and outer diffusers create an even beam without hot spots. The FastBox has an adjustable 120° angle and features a twist lock stand adapter that can be attached to any standard 5/8" stud.

The separately available adapter rings allow the mount to be attached to on-camera-type flash units and Profoto-A mount or Godox V1 mount compatible lights.

Poor Bracket to Stand Lock System

By Phillip
Rated 3 out of 5
Date: 2026-05-30

The only thing that makes this softbox problematic is the darn twist “lock” mechanism to mount to a stand. Everything else about it is fantastic. When it twists tight, four rubber sides press against the mounting stud to “grip” it, the problem with that is that nearly all mounting studs/baby pins and so on all have the notched/concave section to keep screw down type mounting systems from slipping off the mount. This means that the twist lock has not much surface area to grip on to; just the ring at the top of the stud and a small amount at the bottom. It makes for a very insecure mounting system and will spin in the wind or slowly sag went mounted at an angle. This makes it very annoying when the light is mounting out of reach and you have yo keep taking the light down to readjust. There’s no reason this shouldn’t have a screw type locking system. That would make this an unbeatable setup. I’ll still use this as an assistant-held light but I can never mount it again without the guaranteed position change.

Quick and easy set-up
