My Nikon Infrared Wireless Remote Control is a simple remote controller with the receiver built into the camera using the ML-L3 trigger that costs only $17.95 (US street price). Unfortunately, it’s line of sight and narrow infrared beam are overly restrictive, i.e. trying to discreetly point the trigger at the camera IR sensor in group and holiday family pictures or pointing at the tiny front/rear IR sensor when at odd angles to the camera, etc. and a very short line of sight range (approximately 16-feet), is likely to make you miss that precious shot.

The Nikon wireless (radio frequency) WR-R10/T10 combination remote control is a WHOPPING $162.90 (US street price) but I was willing to give it a chance. The WR-R10 is a Transceiver and the WR-T10 is a Transmitter trigger similar to the ML-L3. Build quality is also similar to the ML-L3 - it is solidly built and looks like it will last a long time and it is made in Japan. Hopefully, the button spring is of high quality and will last a long time too. The supplied owner’s manual is a horrible large piece of thin paper folded into numerous little squares in 7 different languages, and is a pain to use without a large and powerful loupe.
A CR2032 3V Lithium Battery (included) is required for the WR-T10 remote trigger and is expected to last for approximately 10,000 releases, the WR-R10 gets power from the camera’s battery. The WR-R10 Transceiver plugs directly into the accessory terminal on my D7200 but does not fit with a regular one piece L-Bracket mounted. However, with my 2-piece Kirk L-Bracket installed, if the side “L” bracket piece is removed it works fine with the camera bottom plate section installed, without any interference.

It also works just fine using a ball head in portrait orientation if you use the ball head portrait slot/grove. When you insert the WR-R10 into your camera and switch the camera's power ON a green LED light will blink quickly several times while it initiates (this only takes a few seconds), when completed the same LED will begin to blink once every 2-seconds for as long as the camera is turned on. The blinking green LED tells you it is working, but it can be distracting. The WR-R10 does extend from the camera about 1-inch so be careful not to hit it on anything because it looks like it could be easily damaged. Included for free is the WR-R10 Strap that is supposed to attach the WR-R10 to your camera strap when not being used, but would allow it to freely dangle and possibly be exposed to damage –I find it better to store it in a camera bag or shirt pocket.
There are three different radio frequencies to prevent any interference from other photographers using one, atomic (auto-setting) clocks, wireless on/off light triggers, etc. CH15 = 2.475GHz, CH10 = 2.450GHz, CH5 = 2.425GHz. It comes paired (synchronized) to channel 15. If changing frequencies the WR-R10 and WR-T10 must be frequency paired (synchronized), this is quickly done requiring only a few seconds and is easy to do. The WR-T10 remote trigger has an Fn button that can remotely control whatever function is assigned to the Fn button on your camera, IF you are using D4 and/or D800 Series cameras (Pro bodies).
If using a Nikon camera that has the 10-pin remote terminal (e.g. D810) you need to buy the WR-A10 Adapter ($59.00 US street price) or, for a better deal purchase the WR-R10/WR-T10/WR-A10 Wireless Remote Adapter Set that includes all three pieces (street price $179.99). For the advanced amateurs and professionals out there, when using a camera with the WR-A10 adapter you can control up to 64 devices!!!
