Fotodiox has a new flash trigger system, the WonderBurst NEX, which features the unique NEX flash mount transmitter and a traditional hot shoe receiver. The wireless units feature 16 selectable channels and a 300′ range.
These are manual-only triggers and do not transmit TTL info and the manual flash sync speeds are limited to 1/160s. Still yet, it’s a very affordable system at only $40 for the transmitter and receiver package. Check it out here on Amazon.com.
