Which is the best frequency? US or CE?
Quote from PocketWizard website:
In North and South America (and some parts of Asia) we use the 340 –354 MHz range because it is the least crowded frequency range for ourclass of wireless triggering devices. Other choices like 433 MHz, 900– 930 MHz ISM band, or the 2.4 GHz band have many more interferingdevices on them.
In our research, we found millions of devices on these bands whereas between 340-354MHz there was much less crowding. A less crowdedfrequency improves reliability and reduces the possibility of missedshots due to interference.
USA Model = 344.0 MHz Frequency
CE Model = 433 MHz Frequency
The PocketWizard MiniTT1 Radio Slave Transmitter is part of an ultra-versatile radio slave system, and is dedicated specifically to the Canon E-TTL II flash control system. It simply slides directly into the camera's hot shoe, and there are no special settings to make or modes to call up. Use the camera, on-camera flash, or flash commander controls for flash compensation, zone and ratio control. It supports single or multiple dedicated flash units.
The MiniTT1 is the ideal addition to any Canon E-TTL II flash system. It works in combination with the MiniTT1 Transceiver, and since this system works on digital radio technology, it can support E-TTL operation up to an amazing 800', even around corners, out-of-sight, or in bright sunlight.
2 Channel Settings + Learn Mode
Each setting can be programmed to support up to 20 ControlTL channels for TTL photography, or 32 standard channels for manual flash photography. The MiniTT1 Transceiver also has a three-zone selector switch, which integrates with Canon zones and ratios. The Learn Mode allows the unit to detect the channel used by any other unit in the area.
Operates on the same channels as all other PocketWizards and will work with any unit you may already have.
HyperSync & High-Speed Sync Technology
Supports flash sync speeds of up to 1/500th sec. High-Speed Sync auto syncs flash system with the camera's shutter speed setting, up to 1/8000th.
Built-in Hot Shoe
Features a hot shoe on the top, so that you can still mount a flash unit directly onto the camera. This allows you to combine your remote flash with the on-camera flash, or use the on-camera flash for additional E-TTL II control only.
The MiniTT1 lies flat to stay out of the way and uses a flip-up antenna for additional range when needed.
Configurable and Upgradeable
The MiniTT1 features a mini-USB port, which makes it upgradeable and "future-proof" for continuous improvements and compatibility upgrades. The included PocketWizard Utility software allows you to select custom settings through the USB connection, and to set it to use specific channels used by other Pocked Wizard units.
Units sold in USA use 344.0 MHz for channels 1-16, and 346.5-354.0 MHz for channels 17-32
Units sold in Europe use 433.62 MHz for channels 1-16, and 434.22 for channels 17-32
USA and Euro models cannot converse with each other
