[QUOTE="WayneF, post: 451580, member: 12496"] No, for flash, the transmitter on the camera does not use a cable. It is in the hot shoe, and the hot shoe triggers it (same as if it were a hot shoe flash), causing it to send radio trigger signal to the receiver on the remote flash. But it is a simple on-off trigger signal, which cannot send complex TTL information to the flash, so it is manual flash mode only. (Before someone pipes up to say same, yes, there are other brands at greatly more cost that do try to approximate a TTL function in a remote trigger. But not for $25.) Guessing, I ASSUME (because of brand and appearance and price) that the kit trigger is this FC-16 one: [URL="http://www.amazon.com/Neewer-Multi-Channel-Wireless-Trigger-Shutter/dp/B00OUKQP1O/ref=sr_1_3?ie=UTF8&qid=1431441387&sr=8-3&keywords=neewer+trigger"]Amazon.com: Neewer FC-16 Multi-Channel 2.4GHz 3-IN-1 Wireless Flash/Studio Flash Trigger with Remote Shutter for Nikon D7100 D7000 D5100 D5000 D3200 D3100 D600 D90 D800E D800 D700 D300S D300 D200 D4 D3S D3X D2Xs: Camera & Photo[/URL] This separate trigger kit shows more cables than the big kit, but that might just be the picture? You only need the right cable for your camera model. Radio triggers have a transmitter unit and a receiver unit. Some are separate and dedicated TX and RX units like this one, or some (Yongnuo RF-603) are identical units with a switch to select which function to be. If you have two remote flashes, you need either two receivers, or, usually the second flash can be set to simple S1 optical slave mode, triggered in sync by the flash of the first manual flash. For flash use, the transmitter on the hot shoe, and the receiver on the flash foot. No cable. For camera remote shutter use, the opposite, transmitter held in hand with finger on button, and receiver parked on the hot shoe (just for convenience, it can also dangle on cord, the hot shoe is not "used" for shutter), with a cable to the camera socket to activate shutter. Half press of transmitter button should cause camera focus, same as always. The cable has to match the cameras socket, which vary with model. And my bet is that this mode will NOT also trigger another receiver on a remote flash. I guess it depends on price. My notion is that the flash diffusers are worthless, too tiny to do anything (not really any larger than the flash head). Soft light needs BIG, like an umbrella. The larger one might soften macro use a bit (a little larger would be better), but it's pointless at six feet. Just inexpensive items to add to the kit count. :) Opinions may vary, but when you try to examine the actual difference it makes, it is a very hard go. The main actual difference is to require a bit more flash power, which slightly raises the color temperature, a bit more red, warming, which we tend to like. But bounce flash is vastly better in that and all other ways. Another Opinion: Unless your goal is studio portraits (umbrellas), my guess is that we all use much more walk-around hot shoe flash ([URL="http://www.scantips.com/lights/flashbasics1d.html"]especially bounce flash indoors[/URL], which is the really good stuff, for good lighting, and for convenience).
