I bought my Calumet Umbrella Adapter from Calumet, obviously. You can secure yours here.
After much research on what umbrella adapter to pair to my Bogen nano 001b, I finally stumbled across the Calumet Umbrella Adapter from the Strobist website. I was scouring the ends of the Internet to find the perfect setup. My criteria was simple: it had to hold my Nikon strobes safely and securely without falling off. I will not be a happy camper if my adapter decides to lose it’s grip on my SBs. The Calumet design is simple, yet thoughtful. The hot shoe mount is recessed to prevent the strobe’s hot shoe from shorting out; the clamp has a spring tensioner to ensure a tight grasp againts the strobe’s hot shot. It also comes with another female mount insert for different light stands. I ended up removing the adapter and screwing the mount directly to the 001b.
The Wescott 43″ umbrella (model: WEU43WS) is what I have and it’s stays in the holder quite nicely. I’m not too crazy about the umbrella’s build quality, but it’s only a minor gripe. It’s definitely worth having for the price.
I’ve used other umbrella adapters, but their clamps don’t feature a spring for resistance. Often times the knobs that screw onto the side of the hot shoe are just too darn small to tighten properly and securely. They also don’t have the recessed hot shoe groove. Here’s an example of what I’m talking about: Smith-Vector adapter.
I’ve read complaints about strobes falling off these mounts and have had experience with an SB-900, a $400 flash, falling off. Luckily I have tiger-like reflexes and caught it!
I did consider this setup: a Stroboframe Flash Mount Adapter (~$15) paired with the Bogen 026 Swivel Umbrella Adapter (~$30), but that alone is a ~$45 USD setup. The Calumet adapter is less than half of that setup and is a single piece.
I’m very impressed with the build quality and would buy another one if I had to. I ended up buying two. And for $17.99 before shipping, it’s not a bad deal.
