Hello Timz,
The S2000 is a very nice flash. When using wide angle is use it on full power manual. The TTL works great, when not doing wide angle i set my camera on 'fill-in flash' (don't know is this is translated correctly, but it is the mode were the camera decides how strong it needs to flash), and i practically never need to adjust anything. The flash is connected via the FO cable and works 100% of the time!!
Greating Danny.
