Re: wireless flash on NEX 7

All camera manufacturers use optical triggering for their remote flash systems, Sony, Nikon, Canon, and Olympus are ones I've used.

Only third-party products use radio frequencies. Look at the slave flashes, they have these little red windows that receive infra-red frequencies of light. They do not use radios.
