What it is
A bayonet on a studio head, matched by a speed ring on the modifier.
What it does not promise
No published dimension. Fit is checked by naming the mount on both sides.
Where it turns up
Bowens heads include the Godox MS300 kit and the NEEWER Q6. Bowens softboxes include the AMBITFUL FW60x90, Godox EazyFlow and TARION SQ-6090F. The Godox K180A kit is not Bowens.
How to check before buying
Check that both the head and the modifier name the Bowens mount.
What people ask before they commit
Will a Bowens softbox fit my strobe?
If the strobe lists a Bowens mount, yes in practice. The [Godox SK400III-V](/reviews/studio-flash-units-godox/) and [MS300-V](/reviews/studio-flash-units-godox-ver/) both do.
Can speedlights use Bowens modifiers?
With a Bowens speedlight bracket.
Is the Bowens mount a standard?
It is a widely copied shape, with no published document.
