Summary: If you want to ensure the safety and stability of your Nikon Speedlight on a light stand, I recommend the AS-19 Speedlight Stand by Nikon. With the security of a standard (locking) ISO hot shoe mount and metal 1/4"-20 threaded socket built-in, the AS-19 is the perfect solution.
Summary: The AS-19 stand is useful in conjunction with the SU-800 Remote Commander. You can quickly set multiple Nikon flashes around a room using AS-19 stands and control all the flashes with the SU-800.
Summary: Genuine Nikon part for less money than some wanted for cheap knockoffs [@]. There's not much to this item, but if you need off camera flash it's a great strobist accessory.Can hold anything with a hot shoe foot like my wireless flash remotes.
Summary: Great for table top flash work or in situations where you need to tuck the flash away on a flat surface w/o the need for elevation. I don't think the AS-19 works with the bigger foot on the SB-900 however. Metal threads are nice, but I haven't used these on a light stand. That's what umbrella adapters are for.
Pros: Good Value, Lightweight, Long-Lasting, Reliable, Stable and low profile, Versatile
