Nissin have released a new flash the Di866. Seems to have a lot going for it:
- Power level GN60
- Sub fill light (ala Metz)
- Colour LCD that rotates
- Full iTTL AWL CLS support!
- USB cable firmware upgrade
- Lower cost

Some minuses:
- Slow recycling
- Less zoom than SB900

Would be interested to try one out since it will only cost a touch more than an SB600. Anybody tried one?
