When selecting a wireless camera link size, power usage and ease of operation are important factors to consider. That is why I chose the Lectrosonics SR receiver paired with (2) Lectrosonics LMA Transmitters. This system provides a power friendly and high quality system. The Lectrosonics SR Batt sled allows for easy self powering with a Sony “L” Mount style battery for 10+ hours and Using I power 9v I can power each of my LMA Transmitters for 6+ hours. If you’d like assist in building a system I’d be happy to help it is super easy.
