This is used on my Nikon SB-28 flash. As with any IR type device this works best inside. It does work in a softbox, behind a product, or behind furniture. I have placed it in a room off a hallway adding light to that area of a home; it did fire the flash Though it is line of sight, however when placed behind furniture in a large well lighted room it may not fire. Make sure the sensor is facing the sending flash or where it can pick up the bounced flash. When used outside it must face the sending flash. Though I like SU-4 I have purchased Radio Frequency (RF) transmitters and receivers. In more diverse situations, inside outside, and over distances, RF receivers are reliable; whereas IR can be hit or miss.

After I purchased it, I only tested it and then I put it in my storage. Because I eventually decide to get Pocket Wizard for wireless lighting. This one works great for what it is designed for. I like the way it does not require any battery but i do not line the "must-in-sight" requirement.

Some flash devices do not have a sensor to fire them such as the Nikon SB-28. Putting this on the SB-28 provides the ability to place it within my shooting environment having the flash fire. Some Nikon flash, others as well, do not have a IR widow. When you want to fire the SB-28 using wireless this device is a must.

I got it for my sb-700 flashlight, and then discovered that it was not necessary as my D7000 has commander flash available. But the SU-4 eliminates the annoying sound of the flash and has perfect timing with my camera, it can also be used with flashes with no wireless features like the SB-400, cool!!

It evidently doesn't come from Nikon, no SG-1 flash guard (for camera's built-in flash unit) included, which is standard inclusion with a Nikon SU-4.

I use the SU-4 Wireless Remote with Nikon SB-28 flashes in manual mode in my home studio. So far they have proved very reliable.

It allows me to use my SB-28DX with the CLS. It fires every time, it's easy to use, and it has saved me from having to buy a whole new flash.

Ideal for use with Nikon speedlights in multiple flash lighting setups to reduce background shadows, provide a second light for fill or main light purposes, and for background or accent lights.
When connected to an accessory Nikon Speedlight, the SU-4 enables wireless TTL multiple flash control while using the cameras built-in Speedlight as a master unit. The Diffuser SG-2 is provided to reduce the flash output of the built-in Speedlight.
You can use several SU-4 Flash Controllers simultaneously, too.
NOTE: This unit is not compatible with digital SLR cameras.
