I have been using theD70s for a while. When I have needed to use a flash, it has been the built in one on the camera - I have found that this is not that great.
I am looking at buying a flash, obviously the recommended ones are your Speedlight SB - 400 & 600, BUT, they are very expensive. I have found a brand called Nissin, which "seem" good, and costs a lot less. They have models that are compatible with my camera, which seems perfect - My need for a flash is minimal, but I want a better quality one than what comes built in. Has anyone used this brand?, or do you have any suggestions?
