Hi, I recently bought an AB800 from AlienBees. The umbrella I was waiting for has been on backorder forever so I am looking at some sites to order a similar shoot-through umbrella that's convertible for bouncing as well.
One I found is this Photoflex UM-RUT45 (hereon B&H and hereon the official site).
It says the shaft diameter is 8mm, and for AlienBees lights I've found several sources saying that all their lights accept 3/8 inch umbrella shafts.
Will this Photoflex one work in the AB shaft hole? I realize that 3/8 inches equals out to about 9.5mm. Will the 8mm Photoflex one work?
If not, where can I find an umbrella brand that uses the exact right shaft size to fit in the 3/8 inch hole in the AB??
