Depending on what you’re trying to achieve: With Nikon CLS you can overpower ambient light creating dark dramatic backdrops, or dial in just enough flash to accent ambient light using high-speed sync for your outdoor settings, or set a manual shutter sync speed and aperture, then let NIKON CLS figure out “how much” to make perfect exposures. The beauty of CLS is Nikon removes most of the drudgery of trying to figure out multi flash exposures but still provides you an ability to control each flash output + other in camera settings (rear / front) curtain sync & high speed sync up to 1/8000 sec, depending on camera model.
Flexibility: Because the Nikon wireless system is wireless you have awesome flexibility for a number of flash settings and for exact flash placement, you are not stuck with the flashes on the end of the lens. It is enitrely possible to detach the SB-R200s and place them practically anywhere you require. Sometimes I like having one flash set to ½ under exposed and placed slightly behind and over of the flower, which will produce some nice rim lighting. You are limited only by your imagination, the Nikon CLS handles exposure precisely, leaving you to concentrate on the composition and effect you are looking for.
Ease of Use: As mentioned under flexibility, the Nikon wireless R1C1 or R1 is rather simple to use, once you have your flash set using the manual dials and the SU-800 set to match, It can be as easy as hitting the shutter button. Unless you change settings, the system remembers your groups and channel and is ready when you are. I normally make one test shot at the start of each session.
Battery Life: Those darn batteries. A possible downside to this system is they use an odd battery, not bad just different, although easy to find in most stores it is not as available as AA or AAA. Nikon choose to use CR123A. You need 1 battery per device, and I recommend you carry spares when out shooting. I can shoot all day on one set of batteries and still have power, the side story is the following day, you really don’t have a easy way of knowing the charge but will notice the recycle time of your SB-R200s increase as the batteries deplete. You can now find rechargeable replacements, but I have not tried them yet.

What to Carry: As my basic outing carry, I always bring an extra set of batteries both for the camera and the flash system. I also bring along one foot and sometimes the clamp if I am trying to get real creative.
Durability: Three years of solid use with no issues, never had a failure or breakage.
Problems I encountered: The only minor problem I encountered is attaching the adapter rings, especially if you use filters – binding, or the opposite of binding working loose allowing the flashes to rotate down – these are very small issues and are easily solvable.
What if you don’t have a compatible camera: Nikon offers a SC-30 TTL Cord which bridges the SU-800 to the flashes using a wired connection, allowing proper exposure control.
The beetle has both flash fill and ambient lighting.
Using The System in The Field: I currently have and use a Nikkor 105mm 2.8 Micro and a Nikkor 200mm f/4 Micro, The Nikon system integrates perfectly with my Nikon D500, D810 and macro lenses. Depending on your needs you can choose to set your rear / front curtain and sync speeds accordingly. But whatever you set your camera flash settings to the system handles the rest, simply turn on the flashes and SU800 when you are ready to take the picture. The SU800 is smart enough to go into sleep mode when not being used, saving battery and wakes when you use the camera. As mentioned before, you can adjust the output of each flash separately, that is; one flash can be in group A and the other in Group B and you can set group A for 1:3 flash output, or even dial in something like -.3EV. The other neat thing is the SU-800 can be used with almost any Nikon speedlights, great for remote control of multiple flashes like the SB-700, SB900/910 or even the new SB-5000.
Why go full System: You get a SU-800 for about $200.00 additional, and when you get into multi flash photography, the SU-800 is a wonderful compliment by reducing needless in camera settings + some cameras simply do not have pop up flash. The SU-800 offers a more professional approach to flash photography.
Ambient light pushed into dark:Nikon CLS SpeedLight can bring emphasis to the main subject by overpowering ambient light.
The Up Side to the R1C1 / R1 System: It is a easy to use, portable, macro solution that will in almost all situations improve on your already great macro photography. Even if you’re just a casual shooter, this system is a pleasure to use.
The Down Side to the System: It is expensive and is by far the one reason it is not as popular $700.00+ (see alternatives), although light it does add some weight to carry, some folks prefer natural light and rather be free of the added burden.
Alternatives: With sophisticated camera exposure metering system noqw in most cameras; the introduction of LEDs offer macro lighting capabilities on demand starting for as little as $30.00, and have various specialize interfaces for different cameras brands. One issue with ring light is your kind of stuck with the one size fits all, and loose the flexibility of light placement; but these may be worth a try.
