Quantum Instruments Octa Softbox Kit Reviews

Great Small Octobox

By Thomas
Rated 5 out of 5
Date: 2025-03-12

I use this modifier with my Godox A200 flash. It’s great for tight spaces as a key light and really useful as a kicker. I often remove the diffuser cloth and use bare bulb for a more specular effect for wedding reception candids.

Perfect for the Godox AD200 Pro, easy to open and close, very compact.

question

it is compatible whith bowens mount?
Asked by: frank r.
No, the Quantum Instruments QF35 Octa Softbox Kit would not be compatible with Bowens mount flashes. It is specifically designed for use with bare-bulb flashes, such as the options from Quantum Instruments, Bolt, Brilla, Godox, Interfit, or Sunpak. If you are looking for octabox options for the Bowens S-mount, I would recommend the FotodioX EZ-Pro Octagon Softbox (36 , Bowens Speed Ring), B&H # FOEP36OBOW, the FotodioX EZ-Pro Octagon Softbox (48 , Bowens Speed Ring), B&H # FOEP48OBOW, or the Westcott Rapid Box Octa XL for Bowens (36 ) B&H # WE2040S, as options that would work for your usage needs for Bowens S-mount flashes..
