Manual is a wonderful book!
Depends on who writes it.
Try reading the Sigma Flash manual and tell me how much you understand (or the other way round) from it. :sweat:
Its always good to read manual first no matter what equipment you buy because if you don't:
1. you might need a longer learning curve
2. you might not enjoy the full features available
3. you might not use it correctly
4. you might break it (ouch!)
Surprisingly, I found the need to read my 40D manual more so than when upgraded from 300D to 20D simply because the picture modes play a much more important role now and the Live View mode is definitely new as well as the C1, C2 and C3, HDR mode and the list goes on.
So yes, in this case, I read it thoroughly.
