SmallRig Parabolic Softbox Overview

Create a beautiful, even key light for still or video productions with this flexible RA-D85 Parabolic Softbox from SmallRig. Designed to set up and pack away quickly in the included carrying case, the softbox has a 33.1 x 22.4" opening for a strong yet soft and controllable output. Soften the light output with the included internal diffuser, or remove the diffusor to increase the light output. You can mix and match using either or both the internal and external diffusers to soften the light.

Attach the included honeycomb grid to add shape and directionality to the light's output. This softbox is ideal for overhead use on a boom or on a stand, as a beauty light, a product light, a key, or a fill light. It is easy to setup with support ribs on the exterior that won't interfere with the light's output, creating a smooth beam complimentary to faces and products.

Quick Release Speed Ring
The Bowens compatible speed ring travels with softbox attached or collapsed, and features an innovative design that allows you to expand the softbox quickly without having to insert poles into the speed ring.
Reflective Interior
The highly reflective, silver-colored interior helps prevent light from escaping through the fabric, increasing the efficiency and output of the softbox, while helping to create a soft output.
Diffusion
Comes with an external diffusion fabric and an internal diffusion baffle.
Honeycomb Grid
The high-quality fabric grid helps focus your light's beam angle to 45° for more control of your lighting.
Waterproof Exterior
The exterior of the softbox is made with Oxford lattice material, which is water, light, and dustproof to benefit working outdoors and to prevent light from leaking from the softbox.

SmallRig Parabolic Softbox Reviews

Compact and easy setup

By Thomas
Rated 5 out of 5

I have a lot of soft boxes and reflectors, but some of them are such a pain to set up that I have rarely used them. I don’t leave my stuff set up all the time, so it’s great to have a small diffuser with an easy and self contained setup and teardown. Very solid build (though I haven't had too much time with it.) Well worth it.

This softbox is so nice to use. It pops open quick and is very user friendly. It produces very soft light that looks amazing with very little effort. I would reccomend this softbox to anyone.
