According to Lighting Rumours, a new flash has come out to challenge that of the Yongnuo line. Triopo recently announced the TR-981N and TR-981C for Nikon and Canon. The units have i-TTL or E-TTL control, manual adjustment and built-in optical slave cells. Beyond that though, they also sport HSS: which is awesome when you want to get a monolight look or overpower the sun. But that still means that Yongnuo has the advantage with their built in radio system.
The TR-981 features an LCD control panel on the back which is used to adjust settings: much like many other modern day flashes. It also has a PC sync port and a high voltage external power socket. According the manufacturer, the recycle time at full power is 2.9 seconds on new AAs, or 4–5 seconds with older batteries.
