Using soft boxes for an outdoor photo shoot in a windy day is a bad idea. So, I’d love to see a soft box (maybe 2’x3’) that is portable and wind resistant that is like a rectangle magnum reflector.
A fully plastic zoom reflector or magnum OCF reflector could be a good idea and less expensive than the current metal ones. Metal ones can get bent on location. No locking ring is needed. Just a slide on design with some integral tabs that provide pressure to the outside of the light housing to keep it secure. Having a plastic one would be good in that it is less expensive = more sales, and if they get damaged it doesn't hurt the pocketbook as much. It likely won't be as reflective as the metal ones, but in many cases that is not an issue.
