very much appreciate if those who used it (mine bought from konota) can shed some light into the set up.
the spec. states should be used for 300mm and above, inorder for the angle of illumination to cover the angle of view.
tried with friend's d30 + 550ex + 70-200. base on the instruction sheet, it should be use with TTL, but all Canon's Digi cam works only with ETTL.
when mounted normal and took a shot @100 (100x1.6=160mm) pointing @ a wall @ 4-5m away, the flash falls on the top half of the photo.
will the flash falls back to centre as the distant between cam & subject increases? if so, what is the min. dist.?
