Wireless flash technology is starting to make its way into the world of macro photography and we've got a range of cameras and flashes that take advantage of this trend. Getting rid of the power pack and cord (from a traditional macro flash) reduces weight and removes potential connection problems at the camera's hot shoe. Cameras which feature wireless flash transmitters allow you to "re-purpose" the camera's built-in flash and use it to control and trigger an external flash. Proper exposure is assured as the camera uses the same flash metering system that it uses for attached flashes. Nikon has been adding the ability to work with wireless flashes to their mid and high end cameras for many years and Canon has recently started doing this as well. On these camera bodies, the wireless flash transmitter is enabled in the camera menu. To activate the transmitter, simply pop up the camera's built-in flash. Both Nikon and Canon offer a separate wireless flash transmitter for use on their cameras that do not have this feature built-in. Canon's is called the ST-E2 and Nikon's is the SU-800. Both models are lightweight and compact compared to traditional macro flash power packs. Please call us at 800-998-7765 with any questions. Wireless Macro Flashes Nikon was also the first to offer a wireless macro flash - The R1 Macro Flash system - which was announced back in Nov. 2005.The photo at right shows the Nikon mounting ring and flash heads that are part of the Nikon R1 Macro Flash kit. This flash can also be used with our R2 Dual Point Flash Bracket (as shown below) and the Nikon R200 flash heads are available separately. You can also save a few dollars by buying the R2 Bracket with (2) SB-R200 flashes as a kit. Metz is the first flash manufacturer to release a wireless macro flash that is designed to work with most cameras that have wireless capability. Instead of having multiple models for each camera manufacturer, the Metz MS-1 allows you to choose the camera brand in the flash setup menu. The MS-1 is a dual point flash with flash heads on both sides of the lens. Each flash head can swivel independently - straight forward or at either 10 or 20 degrees in towards the lens. Canon is on board as well with a small wireless flash - the 270EX II - which can be used on our R2 Dual Point Flash Bracket. The bracket allows the flash heads to be positioned in close to the lens for intraoral shots or spread out to the side for better anterior esthetic photos and lab communication. Unlike the Nikon R200, the Canon 270EX II flash can also be used on a camera hot shoe as a regular flash. The Nissin i40 is the latest small, wireless flash that can be used on the R2 bracket. It is available in Canon and Nikon versions and can be used with cameras that have wireless flash capability (either built-in or with external transmitters). The Nissin i40 costs a little bit more than the Canon 270EX II and Nikon SB-R200 flashes but the i40 beats them both in terms of power and flexibility: Camera Bodies with Wireless Flash Capability The following Canon and Nikon camera bodies (current and older) have the ability to control wireless flashes without the need for additional equipment. Other bodies would need a wireless flash transmitter. Canon cameras: 7D Mark II, 7D, 70D, 60D, Rebel T6s, Rebel T6i, Rebel T5i, Rebel T4i and Rebel T3i. All other Canon models need the Canon Speedlite Transmitter ST-E2. Nikon Cameras: D70, D70s, D80, D90, D200, D300, D300s, D7000, D7100, D7200, D600, D610, D700, D750, D800/D800E and D810. For other Nikon models, you need Nikon's SU-800 Wireless Speedlight Commander.
