Bolt has put together this TTL Macro Ring Flash with Transceiver Set for Canon for photographers who require the ease of wireless triggering and TTL exposure control backed with options to expand the system.
Suitable for any type of work to illuminate up-close subjects, from flowers to food, utilizing multi-flash setups and flexible wireless communication, the package includes a Transceiver with stand and two VM-1010C Macro Flashes that attach to the included flash mounting ring. Each flash comes with flash stand, diffuser, shoe adapter, soft diffuser, and a nine-color gel filter set with pouch. A padded, zippered case is supplied for the package. Bolt also includes 52, 55, 58, 62, 67, 72, and 77mm lens adapters to accommodate most lenses.
Ideal for use as a small unit but even better used as one of up to eight flashes configured as a ring flash for small objects via the appropriate accessories, the VM-1010C TTL Macro Ring Flash from Bolt has a guide number of 33' and a color temperature of 5500K. The head also has an LED modeling light with an accuracy rating of CRI90 that means that you can also use it for video. The VM-1010C has a built-in wireless receiver that operates on the 2.4 GHz wavelength and accepts signals to trigger it and vary the power at distances up to 328'. The VM-1010 has output that's variable from 1/128 to 1/1 in Manual Mode and ±3 stops in TTL. It runs on four separately-purchased AAA batteries.
Working within the Canon TTL system, the VM-1020C Transceiver has 16 channels to prohibit interference from other shooters using radio systems. The Transceiver can control and trigger one or multiple Ring Flash units attached to the system's mounting ring, or off-camera using the 2.4GHz wireless radio operating frequency. Since it has a dedicated hot shoe, you can mount a Canon flash on it and shoot on-camera while controlling off-camera flashes. The VM-1020C Transceiver has three groups. Assigning ring flashes to separate groups allows you to light different parts of a large scene or work three individual setups from the camera. The VM-1020C Transceiver supports High-Speed Sync up to 1/8000 second for controlling bright backgrounds, shooting at wide apertures or creating an appealing background blur for creative effect. The VM-1010C runs on two easily-sourced AA batteries.
The flash can slide around the included ring for correct positioning. In fact, you can mount up to eight macro flashes and adjust their angles from -45 to 60 degrees.
